Top Speed or Fast Intentions???

That being said, the FI TDX system is a truly top notch exhaust, made right here in the USA by Tony. It does produce more power than the TS exhaust, and personally, I think it looks better. It's really down to what you are looking for in the exhausts - they both sound different, and if power doesn't really matter to you, then the only variables are sound and price.
