Exhaust for 5.7 TPI

[IROC-Z Man]

What would be the best exhaust set up for an 89 IROC-Z 350 TPI? Cuz i still have the stock Y pip exhaust and i like the turn downs so can i get a little advice?

Well i got the american thunder series flowmaster on mine but they arent turn downs its 3 inch straight out the back but it sounds awesome. need more info ill tell ya

BORLA is the best way to go, it sounds great throughout the rpm range. They're pricey but it's well worth it for a great exhaust system. I never liked the sound of flowmasters and all that other stuff personally...u get what you pay for. A flowmaster system that costs $350, will give u the performance and sound of a $350 exhaust system, and a $700 Borla system will give you the sound of a $700 exhaust system...simple as that.

The good thing about the borla's is that it'll never rust, and has a lifetime warranty.

There are cat backs out there that will perform just as good and maybe better than a Borla for alot less money. It kinda depends on the sound you want. Different setups have a different sound. What ever you get you want mandrel bends and no smaller than about 2.5 in pipe.

I was wondering if a true dual, x pipe , h pipe, or y pipe would be the best to go with for performance. Sound is ok i'm just looking for the best performance exhaust with as much as possible hp gains. I was told then bigger the back pressure then better
