Re: CAT Delete but keep piping?

it will increase performance but you will need to either get an o2 sim or tune out the o2 sensor thats after the cat because it will throw the sensor off and cause a check light to come on. or you could do it and just leave the light on. but yes, it will increase both performance and exhaust tone will become a lil deeper but may casue a lil more rasp.

i don't have a cat and learned to deal with the light being on. also i have pacesetters and magnaflow without the cat and i really dont get much for rasp until about 4k....

Did you notice any gain or loudness?

If you run a Summit Turbo muffler you won't have any rasp, I have a VS cam , RK sport headers, 3" piping all the way to a 3" cutout (closed currently) and to a 3" in and 3'" out, Summit Turbo muffler with a 3" turn down on the drivers side. No rasp and I shift at 6000 rpms. One might here it chirp 2nd and 3rd gear , but thats about it.
