Exhaust ideas?

[schaferstephen]

Hey all, got a question for yawl. Here's my current exhaust plan: I currently have a stock 200 I6. Eventually I'm going to cam it and add a later 250 head w/ port work and an offenhauser tri-carb setup but NOW, it's bone stock. Except for my beautiful CI headers! I have a Borla muffler on the way. I'm thinking that now, a dual exhaust is totally unnecessary. I have a Y-pipe. I'm thinking clamp the Y pipe on the headers, weld a 2.5 - 2" reducer on, and run a single 2" tailpipe back to the muffler. Later when I have my engine build completed (which won't be for a good while,) I'll go to a true-dual setup. What do yall think about this plan? I have friends that will help me with the hanging, welding, etc. which is why I'm considering this.

Now let me ask this.. What are the benefits/losses of running a side out right in front of the rear axle? From what I understand, Borla's don't have a whole lot of drone. I like this idea because it will be easier for us to do than fabricate a bend over the axle, and honestly... it looks SO COOL. What are some opinions on this?

'Preciate the help (again) yall!!

no other replies, I'll give it a shot -
I don't know...I guess (w/o much thought): blastin the pedestrians and right lane drivers, commin in yer own windows when they're down, less expense due to less pipe, need for customizing rather than off the shelf prts, less ground clearance, possibility for 'stains' on that side of the vehicle (depending on multiple factors)?...

That's what I am going to do on my '67 Mustang later this summer. Bone simple, the tone is controlled by the muffler that you chose. There are a lot of new vehicles that come with exhaust exits in front of the rear wheel now, so it's not completely a rebel move anymore. I do expect to lose ground clearance but that's OK, 99.3% of my driving is on open highway (long flat ND highway)

I am going with a single out on the passenger side, so if there is any loud noise I will be on the opposite side of the car from it

I have a Flowmaster 40 on a 2" pipe. It does not drone as others claim it will. It has a nice low rumble that gets big when I stand on the gas. I found that the noise level inside the car went down when I put a 6" extension with a turndown tip on the tailpipe to get it out just past the rear bumper.

I personally prefer an exhaust system that goes over the axle and out the back of the car...but that's me. I think I would run the duals now so you don't have to re-visit that again later.

What i'm intending to do, and have done on a couple other vehicles i've owned, is a single-in, dual-out Flowmaster, and I have the tips run behind the rear wheels and exiting down at an angle maybe 1/2" below the rear quarter tucked right behind the rear wheelwells... looked and sounded great on the S10 and Blazer, now going to go with the same idea on my Fairmont with my I6...

.... there is a single in, duel out flowmaster??.. haven't seen one of those - I was thinking of using a single 40 (as per Lidwig's post) .. do these dual-outs sound nicer?
I want something, again as per Ludwig, that gives a nice low rumble. I'd like to keep to original manifold but would consider headers - are they necessary for a nice burble???????

Thanks!

You might want to look at the exhaust system someone on this forum recently put on a Falcon Convertible (search the term David Vizard).

Thanks guys. I think what I'm gonna do is run it straight to the muffler with my friend, then go to an exhaust shop and have them finish it out over the axle.

This approach is pretty cool:
