Would a 3" exhaust with the set up on my other post work well with what I'm doing? I want to run the 3" exhaust that will have a X-pipe with super 40's or super 44's depending on my mood when I order them. This question is strickly for the purpose of performance. I know it should sound good.

Larger exhaust will not increase horsepower, but will allow what you have under the hood to be more "useful", in other words you won't loose as much horsepower with a lower back pressure. Routing exhaust pipe is a pain, and rather dual, versus single with a larger diameter might be the way to go.

So, it's safe to say I won't "lose" any horsepower either? That's the only thing I'm worried about. I plan to run dual exhaust with the x-pipe, as far as routing goes, that's what the exhuast shop is for!!!! I had dual 3" on my 82 cutlass and I wouldn't of done it myself for anything.

Horsepower loss is due to exhaust piping, you want to run (ex) open exhaust headers, you will realize almost zero horsepower loss.

What do you think if I were to bring the exhaust out in front the the rear tire? Think this would eliminate flow problems of going over the axle?

Take a crayon and draw a thick line down your exhaust until about the middle of the car.
Then start it up and go race a 1/4 mile.
Where ever the crayon is still left unmelted, is where it's safe to dump your exhaust off at.
My opinion only, though.

I believe having an X pipe and full exhaust is worth more horsepower than straight dual exhaust, however.

Oh yea, I'm all about the X-pipe.

That's the set-up I have on my Delta, only I have 2.5" x pipe with Super 40's

Sounds good, works good.

SPEEDROCKET

So you think a complete 2.5 will be totally adequate with out losing any power on this application then? If so I'll go with that. I just need to come up with something before I order the mufflers so that i get the right size.

X pipe equalizes the exhaust flow, so if you are going to have 400+ hp, 3 inch is fine

I'm hoping for about that much!!! Thats what's prompting this inquiry!!
