    Best performanc exhaust?

    Let's put the sound question aside for this one. What is the best performance exhaust system on the market for an LS1? I've heard Borla, Pypes, Magnaflow and Flowmaster. Any thoughts?

    Flowmaster is at the bottom performance wise.

    Past that, it really depends on the sound.
    I personally like Magnaflow and the GMMG.

    It is argueably the loudest and best flowing cat back on the market till date. Hence the name "LOUDmouth," it doesnt have a muffler for gods sake. Going up a hill in 4th at 2K rpm is unbearably loud. I had to scream to my friend and couldnt listen to the radio. But around town its fine as long as u dont push it. Get ready for complaints and gettign pulled over like i did. (but no tickets, had nothing to charge me with) but from outside IT IS LOOOUUUDDD. I had my rev his car up to just 2.5K and it sounded like a nascar.

    The air lid is a must. I want the right exhaust to go with it. Never heard of corsa. Affordable?
