Has anyone put on an aftermarket exhaust? Wondering if any problems will occur like any codes?
Thanks

I have had an aftermarket catback for over a year and a half with no issues at all. I would suggest an aftermarket air intake as well to get a better sound.

Steve what exhaust is that? Who did you get it from and if you don't mind what did you pay for it.

I got it from a seller on Alibaba but it doesn't seem to exist anymore. I only paid $300 but the shipping was $350.

Do you have any pics with it on the car?

Is that Mt Cheam in the background? LOL.

I am running HKS, no problems, no codes.

I'm running a muffler delete. No issues. No codes.

Ive got the ebay special installed.... Car hasn't blown up yet

If I were to do it again I would go with muffler delete like nabbun!

It sounds so amazing. And, it's weight reduction off the rear end so it doesn't have the battery pack squat anymore!

does having any of these exhaust effect the mpg?

My exhaust had no impact on mpg, negative nor positive.... Ymmv

Same for me, no noticeable impact on MPG
