Total Exhaust Replacement

[hijinx]

After much research I just ordered a complete engine-back exhaust replacement from Houston Performance (great guys, can't say enough good things about them, they put up with my constant questions )

Here it is:

BBK Longtube headers
BBK Shortie H pipe w/cats
Magnaflow catback

All aftermarket from the engine back.
What kind of performance gains should I see? A mechanic friend of mine said about 10%, maybe more seeing as how it's all aftermarket... so 30 hp or so?

The car and all the mods are on the homepage in the sig.
I can't wait to hear this thing. Booyah!

Most I've ever seen posted was 7 HP from a full Bassini setup. Will probably sound good though.

I would say a minimum of 15 rwhp, maybe more. Let us know.

I'll go between both and say about 10HP. But I will agree that it's gonna sound bad a**.

I would say you are going to see quite a bit more than what others are saying, siply becuase of the longtube headers. I would guess between 20-25 hp total on this system, but what will really go up is your tq and thats what these engines need!

i agree w/ quicksnake, b/c of the longtubes. and as for the sound, i just replaced the mufflers w/ 2-chambers (make sure you get the delta flow ones if you get these) and that alone makes it sound pretty bad-ass.
