I have a 2014 ML63 with the performance package and am looking for options to upgrade the exhaust. Any recommendations?

Also does upgrading exhaust void the warranty?

Hi i have deleted my resonator and replaced it with straight pipe. it sounds perfect, how it should sound at idle sounds stock, but when full throttle beast wakes up.

you can do a resonator delete and do a exhaust cutout sounds even better

I would not buy an exhaust. I removed the resonator and straight piped to the stock muffler, it was well worth it and the ML63 sounds night and day better. No drone at all, and in my opinion the SUV should have come this way from the factory.

Do you have any pictures of your setup

scottiekay

there is nothing really to show a pic of other then the resonator ( center of the car ) was removed and replaced with straight pipes. should not cost you any more then $200 for the work to be done from a muffler shop and the level of fun goes to a 10 from a 6.

did you use 3" stainless?

scottiekay

I think they did, I forget the specific's of the inches but it was stainless because it was more $ for that. regardless it will the cheapest thing you can do to make that car sound mean. The guys at the muffler shop could not believe how much louder it got by just removing that resonator.

+1 for the res delete.
I just had this done on my ML63 and it sounds perfect.

Had mine done yesterday. Pretty quiet at idle and normal driving. No drone. A little loud on wot but I'll probably stay with it.

Let us know what you think. I did it to my SL55 that I had for years and never reverted to stock. The ML, however, is a little louder.

Center resonator removed, 2 1/2" electric cut outs installed with x-pipe. Closed idle sounds close to stock, Much loader when stepped into. Cut outs opened releases hounds of hell. X-pipe smooths out sound. Downpipes next.

I have these downpipe and highly recommend them. They fit perfectly, no check engine light and sound amazing.

I just deleted the resonators on my 2013. Quite tame on idle and light throttle, super mean when giving it gas. My wife definitely noticed and commented that its 'very aggressive' - however, we'll stick with it for now.

what is the gain of going to the cat'ed downpipes? At $2500 plus install I hope it's noticeable

Any videos of this, It must be mega

I never dyno'd my car. Rado says, "+18 horsepower and +26 ft./lbs. of torque."

Large part of the cost are the 300 cell metallic GESi Ultra High Output catalytic converters. I wanted something that doesn't trigger a check engine light without having to modify my ECU or

400 cell ceramic from Magnaflow are cheaper around $130 each and will eliminate a check engine light as well, but I prefer the GESi.

Sounds awesome, i was your first like on the video...lol. What wheels are those they look great? Last question what is the stock width on our 21" wheels are they 9.5 / 10 or 10.5?

Robert Lewis

Rotiform SPF 22X10. I believe stock was 21x10.5

Stock are 21*10

Supermax!

You can remove resonator and still pass smog. It's the catalytic converters that are on the down pipes that will impact smog.

Supermax!
