just purchased 01 z06 with turbonicts t-60 turbo. car has 15,000 miles and quick shift and mod. clutch. Car is running 7lb. of boost.
told car would be pushing close to 500 rwhp but yet to have dyno. I have owned other vettes but never anything with a turbo. I have factory exhaust on it and i have been told certain exhaust could really restrict turbos performance. anyone with any advice please???

I have seen dyno graphs showing a 50 HP jump after installing Borla Stingers in a turbo-charged C5 that had a stock exhaust before. Of course, a free-flowing intake filter is also essential to "let her breathe". Although quite a few aftermarket cat-back exhaust systems produce much better flow than the OEM setup, I like the sound of the Borlas best of all.

Here's a link to various exhaust system sound clips:

I have the Borla Stingers on my car and I love the sound of them. I have yet to hear another too many exhaust systems that I like better than my own. I have a link to a sound clip of my car under my photo in my sig; check it out.

thanks for advice pay2play car sounds great
