Just wondering if anyone that is running an offroad x pipe with an aftermarket catback,has done anything to improve noise levels inside the car. I've put some sound deadening in my trunk, and it's helped a little, but my car still roars at highway speeds. It sucks when my girl is in the car, but I don't mind it to much when I'm driving alone. I'm thinking of putting some high flow cats to quiet it down. Any advice Guys???
Keep the girl and the exhaust...just explain your "NO TALKING in the Cobra" rule! It gets even louder with a gear, I used to just turn the radio off and enjoy the engine/exhaust sound above 55 mph. Catted-pipe will quiet things down and may return a little torque, sell your Bassani on eBay for 60-75% of it's cost.
