Whats Up!

Which Y-Pipe do you guys highly recommend? Stillen or Cattman? I heard that the installation of the STillen is more difficult because it requires some modification. Is that true?

Has anyone heard of the RT cat? Anyone using it? What I ultimately want to do is install a Y-Pipe, high flow cat, and a cat back exhaust. Just want to get the right combination.

Y with GReddy (straight thru muffler) is loud even with RT Cat.

 

Go with the Cattman Y, its SS but i tink it goes for 500. You can always get the aluminized one and have it jet-coated. I'd say at least 40% of us here have the Y-Pipe, check out the sigs. Yes, we have heard of the R/T cat, again many here use that with the Y-pipe. With that combo expect gains around 10-15hp increase.

 

I'm one of those running the RT Cat. Gave me another .1-.2sec in the 1/4 runs.

That was my 1st exhaust upgrade. Everybody at one of the Solo races loved the sound it made with the other stock pieces.

Next was the Cattman SS Y-pipe. BIG improvement but doesn't fit to the RT Cat flanges.

My b-pipe is on the way along with some custom welding to fix the RT prob. Keeping the stock muffler.

Should be a potent combo without much more noice (I hope)
I'll see if I can run 14.7 or less with the cold temp now...
