Resonator Removal?

Where is the best place to take my car to get the resonator removed? I live in the Houston area. My car has a Remus muffler on it and I want it to sound a bit deeper. Will removing it make a noticeable difference in the tone?

A million people have done this since the Remus is so quiet, any local exhaust shop can do it for like 30-40 bucks.

Oh i dont know about your exhaust, but i heard the remus on a X5 with them removed, it sounded WACK..... By the way, does anyone know if a car without resonaters will pass inspection, or if it will mess with the O2 sensor

Keep in mind the effect differs from each model...

I removed the resonator from my 330Ci and it sounds different than the resonator removed from my buddy's 323i.

I want to have my resonators removed also. I have an AC-S Exhaust system and it is just way way too quiet for my tastes. I don't think it will mess with the O2 sensors. They are on the exhaust manifold ahead of the resonators.

Yup the sensors are up front..........you can chop those Ressies off without a problem.

There are pre-cat and post-cat O2 sensors. Located on the exhaust manifold/(headers correct term?)

I think I may have worded it wrong, they are "ahead" meaning towards the front of the car, before the resonators.

I removed one, but will get the second one removed as well. I think it sounds just fine with one removed, deep and not too loud but just right. However on the track I want some more noise out of the car and therfore I will remove my second one as well.

No butt-dyno performance gains...

323s/328s are quieter in stock form than 325s/330s...

Not sure if it will get "louder" if you only remove a resonator and still have the stock "exhaust"/muffler. It'll definitely be louder with an aftermarket "exhaust"/muffler though...

I removed one resonator, the 2nd one which is closest to the muffler, and I love it with my Dinan "exhaust"... ask Hamann99 what he thinks of my setup.

For those considering doing this, start with the 2nd resonator...
