Exhaust

[jasonmatei]

Is it bad if I do a complete straight pipe? Will there be any issues with the O2 sensors or anything? Part of my muffler has a hole in it and I kind of like the noise and I always wanted to straight pipe it. So let me know. Thanks in advance

Hi Jason

A straight pipe will not affect your O2/emissions functionality, as long as you are talking about the middle or rear mufflers. Cats in front is a different story. ;-)

So if I take the rear muffler out, will it be noticeably louder ?

Yes it will. If you leave the center section and delete the mufflers it will be louder. If you remove the cats or gut them I think you have to retune the ecu and maybe even do an O2 delete in the ecu on the rear 2 O2 sensors. Not sure on that last bit just repeating what I have read. This guy says its all stock except for muffler delete. https://www.youtube.com/watch?v=0ddCze7CyCc

You can take off the mufflers (straight pipe them) but it might drone like crazy at certain rmps. Like everyone else said ditching the cats will mean some fixes
