Headers and dual exhaust

Post #1 by 67drewstang » Mon Jul 01, 2013 11:31 pm

I am gradually upgrading my 200 ci I-6 1967 Mustang convertible. Since the exhaust is starting to go, I am considering installing headers and dual exhaust.

Anyone want to advocate for any particular brand of header? How about exhaust arrangement? I am looking for a nice sound and am not afraid of a little exhaust noise, as long as it doesn't sound like a tractor....

I have the 2" dual impostor stainless steel kit from Classic Inlines. Very nice had to modify some but that almost goes with everything.

I installed the SS header from mike and it sounds nice. Did have issues with the AC compressor mount, AC hisses and Alternator bracket. Not saying not to do it just be aware it requires some modifications. I still have not reconnected my AC. I need to have longer hoses made.

I would get the headers and down pipes with a x pipe from CI. Then have a shop do the rest after you install them. I have the whole kit from CI and the fit is not great. I still have to go to a shop and have the rebend on e of the pipes and do new pipes from the muffle back so the tuck up better. Plus my Ceramic coating is flaking off. Sent Mike an email but have not heard anything back about it. I think I will pull the headers off and wrap them since the coating in coming off.

You should have a high mount. The starter at the top of the bellhousing

I put Mike's dual headers on a few years ago and switched to the 429 CJ starter (smaller body) and have no problems with fitment or access. I did my own exhaust adding an H pipe and then Borlas before finishing with dual exhausts. I have not had a single problem with the system since day one. (I did have a crack at the H pipe which I touched up this summer) Even with my T5, I have plenty of clearance. Once you loop over the tranny, its all standard V8 exhaust from there out to the back end.
IMHO its the best thing (cheapest) upgrade for running and performance that you can do for your car. At first I regretted not getting the chrome exhausts (trumpets) but since time soothes all wounds, I am better off without it. I have the backup lights and it would just be too busy back there.

I'm running hooker headers to true dual flowmaster 40 mufflers and absolutely love it. There's a little bit of a drone once I'm going over 60 mph...but i like it :)

My 66 Mustang has a 200ci stock engine. Installed a single header from cjpony parts and replaced the stock 1.75" exhaust pipe with a 2" pipe, and installed a flowmaster 40 muffler. Great sound at idle and low-mid rpms. However I noticed an annoying drone sound at mid and high rpms. I installed a resonator between muffler and tail pipe. Drone is gone. I might try a dynomax turbo muffler w/o the resonator in the next few weeks.

I took my car to the muffler shop yesterday and installed true dual 1.75" exhaust pipes with 2 Flowmaster 40 and no resonator. The car has a nice rumble and sounds great, not too loud. It really sounds like a stock small block v8.

I replaced the Flowmaster 40 with Flowmaster 50. The 50 is not too loud compared to the 40s.
My advice is: if you want an aggressive sound, then get a Flowmaster 40 (add a resonator to get rid of the drone at mid-high RPMs). If you want a mild sound (a little louder than stock, but not loud), get a Flowmaster 50.
