Suggestions on re-doing my exhaust?

If you want two tailpipes out the back, just weld a pipe out the driver side w/o hooking it up.

It will do about as much good...

but, but, but.........that wouldn't let the blue smoke pour out evenly.
 
I've always loved the sound of an XKE. They used duals, no h- or x-pipe. There was usually a chambered muffler midway in the system with a small resonator at the rear. Here's a couple of clips.

Another inline with a great sound is the BMW M3. The stock M3 exhaust employs a crossover x-pipe just ahead of the middle muffler. Not really sure how this aftermarket system is laid out, but the sound is good.

Don't go too big on the pipes. Larger pipes (anything over 2") give a nice rumble at idle, but the smaller pipes (1 7/8" to 2") "sing" more nicely at higher rpm's.
 
I have a dual header with turbos run all the way to the rear bumper(2.25 pipe)-sounds great! I'll see if I can get some clips up here sometime. I think with regards to the backpressure thing, that most cams now take advantage of the scavenging to pull in the fresh intake charge so backpressue in theory would probably hinder that. The only problem I could forsee with too little backpressure would be that the engine would breathe better and may require more air/fuel to meet those demands. Two and a half pipe would just be a way to spend more on materials!
 
I backed my Mustang out of the shop for the first time under its own power last Friday. The exhaust is a single collector Clifford header ceramic coated inside and out to a 2.5" collector. The muffler is a turbo 2.5" single in with dual 2" tailpipes out finished with the classic flared/vented tips through the valence. I was surprised how quite it was. I am anxious to get it out on the street and get some revs going so you can really tell.

I will have some pics and movies coming soon, I hope.

Got my Purple Hornie put in a couple weeks back.. sounds pretty good. The only droning I hear is when I'm idling in gear, and even then it's not bad. The car is actually quieter than when I got it, since it had so many exhaust leaks. I've also heard the car take off from outside it, and it's really not unbearably loud. I kinda like the sound of it.. unlike the Slowmasters on my truck, which I can't stand the sound of. So I'd have to say I'd recommend the Purple Hornie if you were willing to go with a glasspack.
 
How long are those mufflers? I've found that I like the longer mufflers better. Quieter and less of a drone, plus they sound deeper.

I had a single 44" or so on for a while and loved it. Unfortunately, I hit a DEEP pothole and the clamp right behind the headpipe (it was a TIGHT slip fit) hit the edge and was jerked backwards a couple feet, along with the rest of the exhaust :shock:

So, there I was, dragging ten feet of pipe down the road at night and, joy of joys, it was raining. Stopped in front of some dude's house and looked around in the trunk. I had an socket set and a hacksaw, so I let the back hanger off and sawed the pipe in two before the rear axle, all by the glow of my cellphone. The car was so low that I couldn't just pull the pipe out. I was so mad that I left it there, so somebody has a really nice glasspack. I drove to my friend's house with 12" of pipe hanging down. After downing a couple of Excedrins, I borrowed some earplugs and drove home.

It sounded really good at idle, but was excruciatingly loud above 1000 rpm or so.
 
To J. Collins: Those vid clips are awesome! Is it really possible to get one of our FoMoCo 6's to sound like either the Jag or Beemer? I really have no idea. Since we've owned our '66 (bought it in '69), it's always worn stock mufflers. Also, there are no other modified sixes around for me to evaluate.

A couple of years ago, when the MCA held their national meet near us, we attended and I searched the whole place for any other 6's. Only found one! He had a pretty cool setup, with a Clifford header and (not sure what muffler), but his battery had gone dead, so he didn't get the car fired while we were there.

To CrashBob: You're crackin' me up!!!!!

To 66200i6 Ric: Do you know if Clifford still makes the single-outlet header, like you've got? My old catalog from them shows it, but the online cat only shows dual-outlets. Also, do you have your Turbo muffler transverse-mounted, behind the axle - stock-style?

This info is all very much appreciated, guys. I've made some poorly informed and costly mistakes in building my car, so I really want this step to be as right as possible, the first time.
 
I don't think they do, TDR. You would have to give them a call. I purchased mine years ago. I had the header ceramic coated inside and out right out of the box, at Performance Coatings in Auburn Wa. I went with the flat black ceramic in an attempt to keep the exhaust gases from cooling too quickly.

You can't go wrong going though Mike at Classic Inlines (Ford Six Performance). With what Mike has to offer, you could go either way, dual or single collector. I believe that Mike even offers the header coated as well (that's the way to go).

My muffler is installed transverse. I wanted as much clearance as possible. I haven't had a chance yet to get a clear view while it’s on the rack. I will have some pics and video of us leaving the shop very soon.

Ric,

I sure would like to see (and hear) your car. Please post that data when you have it available. Thanks.

Absolutely. The engines are the same configuration with the same firing order. The Jag duals are split 123 - 456 just like many of us have them. But the stock 4.2 liter XKE only uses a 1 7/8" pipe. That tends to push the pitch up just a little higher. IIRC, the M3 uses some smaller-than-you-might-think pipes as well.

I'll try to post some sound clips of the Locost tomorrow. Very similar.
 
I don't reckon they sound quite the same. OHC specs are likely a little different (probably more duration). There are plenty of cammed-up Ford sixes here that will confuse at first, sounding somewhat like a muffled 302C. The most descriptive word I have for the exhaust note is "lazy". It isn't in reality, but that is how it makes an impression.

I've heard a late model OHC Falcon with performance mods and a fairly regular exhaust, and it sort of sounded like the BMW (actually not that nice to my ears). A bit "tinny" when you pushed the clutch in to upshift.

The Jag note I can compare with some of the worked-over Nissan RB series (save for pipe size) and the closest otherwise I've found is the old Waggott DOHC heads.

Seems like everybody is focused on the exhaust as the only source of sound on a car. It's not.

A significant amount of sound can come from a vehicle's intake tract, especially if it has a fairly open design and high flow air filters (like K&Ns) or open velocity stacks on an individual runner intake design. The sound that comes from an engine with open stacks or K&Ns on an engine with each cylinder having its own dedicated carb throat is one that differs enormously from the sound you'd get from the same engine running an intake with all its cylinders drawing from a common carb breathing through a stock style air cleaner housing with a pleated paper element.

In other words, take a 6 cylinder Jag and it'll sound very different with an intake that feeds all of the cylinders off a single 2 barrel and some kind of enclosed American factory air cleaner with a snorkel and a paper element than it will with a trio of side draft Weber DCOEs and open stacks or K&Ns.

A part of the sound you hear comes from things like the valve train, too, though that's less of a factor than the intake.

The point here is that if you want your Ford Inline 6 to sound like a sporty Jag, then you need to duplicate not only the exhaust configuration, but also the intake configuration as best as you are able. That is a bit difficult if you are using a head with an integrally cast log intake manifold, but if you switch to one of Mike's new aluminum heads and go with the side-draft Weber intake, triple 2 barrel side draft throttle bodies with some low-restriction air filters in a wild looking EFI set up, then man, you might just be able to get something pretty close to the sound you are seeking.

:)

Then to complete the sound you need to mount some headers and an exhaust system that uses pipes and mufflers similar to what a souped up vintage Jag might have. I'd look for something as close to a vintage Abarth or Ansa system as I could find. Those things had a sound that was totally sweet.

:D

One last tip. The old Jag XKEs had some louvers in the hood that were probably there to allow hot engine compartment air to escape, but they also let some of that sweet, sweet intake roar out if they had one of the wilder intake set ups. I don't know if any of you would want to louver the hoods on your old Falcons and Mustangs, however.

:)
 
Ive got a rebuilt 200 that im running right now. I hooked up Hooker Dual exhaust headers with stainless pipes. I didnt use an H or X pipe either. I ran them straight back to dual flowmasters which are located just under the front seats. It sounds beautiful, sounds like a old race car. I would definitely lay the soundproofing down underneat the carpet though, the noise does get a little loud without it, almost too loud to hear the radio. I've heard a lot of talk about x and h pipes, but save some money and time, it sounds great with or without it.

Yeah, I can't hear my exhaust at all (18" glasspack).

All I hear is this strange wooshing spooling kinda sound.
 
I'll tell you what I have and love.

Pacemaker ceramic coated, dual out no port divider 2" pipes with generic turbo mufflers located where the V-8 GTs have them mounted stock.

I tried Flowmaster 50s and HATED them. The note was okay, but they resonated why too much when cruising around town and sounded very 'tinny' to me. On the highway, they were great, nice and quiet. Idle sounded nice, and WOT made me grin ear to ear, but the around town cruising noise (and I do me noise) was too much for me.

My generic turbo mufflers sound great all around. No resonance, quiet on the highway. A little more mellow and 'full' sounding and less "tin" noise. Doesn't sound quite so beefy at WOT, but still makes me smile.
 
Hey Cobra - where did you get those "generic turbos"?

I know what you mean about the resonating sound they made. Last year, my wife test drove an '07 Mustang California Special, which someone had goodied-up. Included in the mods were a couple of expensive-looking stainless steel cans up under the back. It sounded great when she fired it up and took off at full honk down the road, with an unlucky sales fella riding shotgun. They came back with the wife all grinning and the sales guy all white. When I drove it however, there was that "resonating" sound, at cruising speed. It was like a loud droning, which seemed to vibrate through the car's entire unibody. No way I could drive a car, which sounds like that.

Thanks for saving me from investing in Flowmasters. I just need to source some turbos.
