Hello supra owners, I own a 94TT auto for over 3 years now. It a great car. The car is stock, the only mod i have is a Greddy turbo timer and a K&N air filter. The car is now 99k mile I commute to work, sad huh? Anyway, I have a few questions: I want to get a Greddy SP exaust, but afraid that it will sound like one of those Civic. How does it actually sound like?? I also looked at the HKS Super Dragger are there any differences. I actually dont like to see such a BIG canister under the car. Will I be noticed the increase in power? Oh, and how easy it is to get it to installed. I like to do the installation myself to save some money. Please advise.
