Exhaust info for a noob
Thanks for the encouragement. I wasn't sure about the exhaust gas issue as the cuts would put the end pieces right near the front of the trunk, but I hear ya. In researching noise, it seems like there's a pretty big difference in reported noise from running without mufflers but with a resonator depending on whether or not you run headers or have stock Logs. You are speaking from your experience with headers and race cats right?

Been thinking about a muffler-ectomy myself. I've got a OE manifolds, power-pipe, resonator. I've heard a few sound clips of similar without mufflers and seems to be livable. My goal is weight loss and a touch more sound. So...if I simply make cuts as show below and pop off the mufflers, can anyone see a reason to finish off the pipes more elaborately than just leaving them as-is? Aside from aesthetics at the rear, any reason to spend the money to add new sections of pipe to carry the exhaust back out to diffuser location?
I toyed with it. But cut-outs adds cost, complexity, and weight. I need to get to my local exhaust guy and get a quote for just bending some tube and adding new tips. Ideally done with v-bands to quick-ish disconnect or come sale time. Will see what they say.

Based on my experience (with other cars), I agree with BLKROKT: the fumes can get nauseating at stop lights or during heavy traffic, and TBH, dumps don't necessarily "sound" that good (if that matters to you) except at WOT which is usually only at the track. V-band connections are super nice, but gonna be $$$ too. Just sayin'

Hello all. I installed x-pipe instead of the resonator on my C63. Now the oil temperature rises to 120 degrees when I go. It used to be 105-110. Why can it be?

So I got my resonator deleted and replaced with straight pipe near the back. That's what I thought we had talked about here and it turns it outo it was actually the secondary cat delete and I ended up getting the wrong thing removed. Lol
To be honest though I do like the sound of it still though so not sure what I should do now and if I screwed up or what...I guess I can get it put back and remove the secondary cat as talked about....advice?
I hope I didn't lose power going this route...if that's the case then I am gonna have the resonator put back in....fml

You did the wrong thing.... I think you researched so much you made it harder than it needed to be. I am the same way. Enjoying this thread. Do you still have your Car?
