Looking to purchase a catless downpipe for my 07 Saturn Sky Redline!

Let me know what you have and how much you'd like!


Thank You!

You are looking for a test pipe. If you just do that it will throw a check engine light for O2 sensor. Just buy a high flow cat or take your cat off and gut it out. Would be easier.

Wouldn't i be better off going up to a 3"? I assume our stock downpipe is only 2.5"

Unless you use a larger turbo and or tune, the size increase isn't going to get you anything.

Get a high flow CAT and then tune.

You are correct. If it's a catless DP you are looking for, then that is what you should be looking for. Just make sure you do your homework and research regarding Tunes,CELs , etc.,etc.

Most common are Solo,Werks, others I believe were\are available at one point.

The Home of WERKSracing products!

I have a Solo catless, and I love it.
