ok I dont know to much about these but does the rs*r dp delete the cat or will it use it,? If yall could please let me know im trying to decide what to get and im not sure thanks guys

 

well that pipe is the best quality item i have ever installed. yes it does delete the cat. in fact
it goes from the turbo all the way to the middle pipe as one peice.fits like a glove and it retains the stock exhust dounut at the turbo.very fast spool up. i love it

 

So you couldnt run a cat at all then huh???

 

I have the RSR Turbo back setup (downpipe and catback) on my car and I love it. The dp is one piece including cat delete. Therefore, no need for a cat.

 

did you have to run a O2 sim

 

From the pics it looks like there is a tube for the second o2 sensor (mechanical o2 fix)

 

after installing the system, the CEL came on and I did use an O2 simulator to rid this problem. The CEL light never came on since.

 

ok great, perrin sells the sims right???

 

I bought mine on ebay...
