the meistershaft SR pipes dont need to be welded, a regular xpipe does need to be welded. Putting the mufflers back on will help reduce the drone and the vibrations. Like I said the best sound IMO is performance mufflers and leave the resonator on, gives nice growl and inside isnt affected barely at all if any. The resonator does 60% of the noise reduction if not more, the mufflers dont do as much

im officially slapping back on my mufflers. I've actually grown accustomed to the drone but after being the driver for lunch with my co-workers, I realized noone will be able to sit in my car (which might not be a bad thing but then taking my mom on her errands comes to mind). Funny thing is my sister dropped by to visit today and was trying to convince me to keep it cus she loved the sound haha.

18 for city and 25 mile for highway. you are not losing much, but incrementaly it does add up with the high gas price. if the sound you like to acheive is worth it then stick to it.

I think Mixfruit got exhaust mods that would calculate for his little drop in MPG. I am not sure but maybe he can tell you if he does or not.

Well, you should always check your tires. But if you think you couldn't get your MPG down to 15 with full-on aggressive driving, try it! When you pull out a stop-light at a "normal" clip, you're often getting < 10 MPG until you're in 4th gear. If you do a lot of city driving and little highway to average it out, you're going to have a very hard time getting above 20 unless you drive with a very light foot off the line. I think it would be very easy to get below 15.

so i noticed on cold start ups theres a noticeable amount of debris coming out from my exhaust. is it because i no longer have a resonator?

Mixedfruits

isnt resonators just for sound pressure? and making it not so loud

bringtherain

i thought it had some filters as well. not quite sure tho hence the question. the smoke and debris coming out the rear and worrisome

Mixedfruits

should be no big deal

When i had my w204 this had to be my favorite mod ! It wasn't too expensive and gave me lots of ummmm pleasure listening to the roar the times when i " floored " the car I say go for it !

I have an x-pipe and magnaflow mufflers, and I totally agree with everything you've said, bringtherain. I LOVE the sound outside, but the in-cabin noise is unbearable (at some RPMs). NOTE: Unbearable might be an exaggeration. It embarrasses me to have guests that are not car enthusiasts in the car even if they don't mind it.

I was going to put my mufflers back on, but unfortunately, I was missing the hanger with the 2 rubber pieces for my left muffler. If anybody has one, I'd love to buy it just in case I ever need it. That very same day, I was talking with a few buddies, and they said keep the mufflers on and dynomat the trunk. So with some help, I had my trunk dynomatted the same day.

I was somewhat disappointed, because the in-cabin noise was more-or-less the same. It might have been slightly quieter, but not enough to amaze me. I haven't driven a lot since I had my trunk dynomatted two weeks ago. College keeps me off the road and in the study room.
