Ok guys. I have a question for the lot of you. I have a '01 C70 Coupe HPT. I want some more out of it. But I DO NOT want to play with the computer. This car already can cruise at 130mph on the freeway without breaking a sweat. I was thinking of putting on that cat back exhaust system from IPD part #WS2188SS. The car has a bit of turbo lag that needs to go, and the exhaust would alleviate that some....correct?? Is the IPD a good system to get. How loud does it make the car?? I don't want to announce myself when I pound on the throttle. I like the sleeper nature of the car and want to keep it that way. A little more rumble than it has now is fine but not like these darn Hondas I see running around here. I can hear them a block away. Are there any other products besides IPD that I should know about?? Thanks for your input.
