UPDATED EXHAUST !

Nothing crazy

Just got my resonator and second cats deleted about 2 days ago.
For those looking to do this I highly recommend it. For the first day sound difference will be minimal, it will be about the 3rd day youll really hear the change, and boy is it music to my ears! IMO it could be louder

I dont think there are any power gains but definitely better throttle response specially in the high rpm's..

some pics:





I have to laugh at myself with my mini cell phone shoots

I actually thought this pic was cool if u notice there was a car passing by on the street..

Depending on the shop, res deletes run 30-60 dollars. I honestly will not pay more than 50 dollars. They just cut it out and weld in a straight pipe, it's relatively easy for most shops. I had mine done for 40 dollars.

is that the catalytic converter in the middle (after the resonators)? I dont think the 05 kompressors have resonators at least from what i saw of my underside today when getting my oil done

the giant thing in the middle is the resonator for the M272 C230. and the thing you see getting cut are the secondary cat.

the M271 C230k doesn't have a resonator. only a primary and a secondary.

it shouldn't. the sensor is behind the primary cat before the secondary.

Absolutely no error codes (knock on wood) as long as you dont take off the primary cats youll be fine, only those have an o2sensor on them.

I will be making a video soon but when its done breakin in, shes still getting grumpier

hands down today was my favorite commute to work

I paid 150 for the whole thing, two cats and a resonator delete, I also believe I got stainless steel piping.

I am sure some have gotten the same mod for much cheaper but there's a shop I rather pay a little extra and keep my bussiness with.

"annoyance" and "self-righteousness", amoung others...
I have res delete w/ flowmaster 50 series, so curious/reluctant all at the same time, as I don't want it too loud (could always delete 2nd cats and put an aftermarket resonator back on)... but did originally just have res delete so I know what that sounds like, so Im also anxious to hear it.

whatever I can do to get the throatiest sound possible.

perhaps deleting the second cats will unlock some more throat that I seek, as its borderline a little too monotone right now. i want to hear more rumble...

okay for all you m272 owners! IT AIN'T NO SECONDARY CATS!!!! THEY ARE JUST SMALL *** RESONATORS!! we basically have two cats and 3 resonators. I just got my straight pipe done and the shop owner thought it was a cat as well but it turns out those two lil midget looking cats are just resonators. So it's not illegal. =)

yeah it got it done! it sounds just a tad bit louder and i get a little raspy noise around 3.5-4k rpm =( but after driving for a while, the noise goes away. i'm pretty happy but could be louder.

and about the secondary cats... iono the guy doing my muffler didn't want to take off those secondary cats cause of it being illegal but did it anyways but later when he was looking at it, he said they were basically resonators and not cats =/ hmmm.... but aither way i got it straight piped from the primary cats!

secondary is only meant to be a semi noise & pollution filter. it does look like a resonator from inside somewhat.
