what company makes the best high flow cats? Im loooking for a set of cats for my o.x pipe just to pass emissions. Also does anybody make a "fake" cat already hollowed out? In Ct they plug in a computer for emissions, but also look under, so as long as Ihave a cat of some sort I should pass

 

I live in CT too. I have the Bassani X-Pipe with High flow cats although it sounds like you already have an or-xpipe, not sure they will fit. Also, I don't think they really look under the car, just find a shady shop that does the test and you should be straight.

 

Yea i already do have the o.r x pipe. As long as they dont look under Im guessing i should pass. Im thinkin I can weld heat sheilds on and if they look under they may think it has cats.

 

for just emissions find two cheap catco cats or something and just punch them out, if you were to run it with high flows random tech makes the best hands down but there expensive, pypes are also real good.

 

SLP makes a good one too.

 

^just dont buy their x-pipe with them, unless you actually like hearing it scrape over speed bumps

 

just use the high flows, unless you like the o/r sound, theres not much hp gain.

 

I see you have the SLP X pipe too. I have it and i guess im lucky enough that there aren't very many speed bumps at all where I live.

 

im taking it to the exhaust shop when im home in june and having them modify the pipe from the manifold to the cats...the pipe is too long and forces the entire exhaust to hang low

my UPR x is just like that, the down-pipe section is too long so it sits too low. mine is all dented from hitting speed bumps
