Hi Guys, just wondering if anyone is running the stock cat back but with aftermarket o2, dump and cat pipes? Was wondering if those mods with a tune will still yeild good numbers?

Well infact its not a standard cat back the rear muffler is modified similar to the 'works' replacement muffler.

Is anyone running stock CB and o2, dump, cat or test pipe with a tune?? please let me know your experiances and numbers etc..

Thanks

i am also thinking about doing the same thing

We actually had a customer that run that same set-up for month and made about 360hp on a Jestr tune .







on a side note we'll have some O2/DP in a few days
