Performance Mods
Hey, any of you folks with ML550s do any performance upgrades: chip tune, headers, intake, blower, etc. My 2008 needs some added life.

Thinking of doing a ML63 catback exhaust and an aftermarket intake. Looking to try and get close to 400 horses.
Chip probably wouldn't do much since it's a N/A engine. Wonder if the headers from the ML63 would work?

eurocharged tune, true dual exhaust with highflow cats. I did that to my c55 and picked up quite a lot of power

Also, how long did it take you to do?

OK here is how I see it. If you want a subtle change this is the mod you want to do. If you want a drastic change the OEM cans/mufflers have to go and replaced with straight through cans.
At start up the tone is definitely deeper. But just when it starts up. Once at idle it sounds as it did before.
From a stop with 25%-50% on the gas pedal that's where you hear the most improvement in sound. Its a deep grunt & rumble. You will love it. I would say 20% increase in sound.
At WOT again it's louder. Not a deep grunt like described from a stop at partial throttle. It's a pitch louder. A GOOD louder. 10% Increase in sound.
At cruising speed on the highway or on any local road. Once the gas pedal is steady it's like you never removed the resonators. You would never know. It sounds just like it did before. Absolutely no cabin noise or droning.
I paid to much IMHO. But time and location was an issue for me. I paid $150. Just to much for 2 x 1.5ft of pipe and an 1.5hrs of work.
But oh well. I'm enjoying it.

Material for pipe
Did you have them replace the resonator with an aluminum or steel pipe and did it require any Mandrel bending?

Thanks
Thanks for the update, have a local shop that will probably do it for cheap. Will stop by and see if they will use stainless steel or aluminum. The last time I had them do this for me on another car it was a 3.5" x 2' cutout and they only charged me $50 but that was many years ago and they used aluminum.

Kudos. Sounds more serious. Owner enhancements is what makes a car more personal and fun to drive.
I have an observation that might help, albeit slight but the exhaust pipes forward of the cut outs have a section where the pipes come closer together. Replacing that as well with an X pipe or a true cross over could add some extra power and can quell popping sounds on decal as well as +mpg.

Im not looking for vastly improved mileage, better proformance without trashing the motor. Dont trash diesels, tuned right and they're sleepers with great mileage. Would like to get a better growel out of the exhaust also.

in that case, maybe ask volkswagen to do it. apparently they know what they are doing
