I am looking at getting some Hi-Flo cats. I am looking at the UR (Ultimate Racing) Cats and the RT (Random Technology) Cats. Which one????? I do want a louder sound and do not want to worry about check lights or running too lean or rich if possible. Besides the $100 price difference, what's the difference and which one should I go with???

 

Why don't u try the Ultimate Racing we haven't heard any problem or not many people have used it yet

 

...I just put on the helix test pipes. No lights came on and the sound is great. Going back out to the track tonight to see if they make any difference on my time.

 

IMO - The Crawford's are the hot setup.
