you'll need an O2 simulator, and it will probably sound ricey. i would go high flow instead but that is because i'm a left wing environmentalist...

I did it with my borla and it sounded like a truck. Then I put on a high flow cat and it sounds decent now. It could be the exhaust helps too. I think it would probally sound good with a fowmaster.1999 Firebird Black<br />A4 3.08 gears<br />Mods: Carbon Fiber Whisper Lid, Raised Air Box, K&N Air Filter, Direct Hits Ignition, Flowmaster American Thunder 3\", 160 Degree Hypertech Thermostat, SLP Fan Switch, 3\" High Flow Cat<br /><a href=\"http://www.cardomain.com/member_pages/view_page.pl?page_id=273903\" target=\"_blank\">My car on Cardomain</a>Comment
