Hey,

So I currently have Weistec DPs installed on my car and it's loud. It's also quite raspy and sounds like a diesel truck when I'm idling. To be 100% honest, it doesn't sound 'sophisticated' at all. I do love the sound it makes under full acceleration.

I am looking to smooth out the sound a little bit and wanted to hear your recommendations.

Would an X-Pipe do the trick? How about an H-Pipe? I don't know much about exhausts.

Also for reference, I do have the PE.

Here is how it currently sounds:


I appreciate everyone's input.

Thanks

Your car already has an H-Pipe.

Did you take out the secondary cats aswell?

Guilty

lol, thx. I literally know nothing about the exhaust on this car.

any suggestions?

Guilty

No. I just have catless downpipes.

vaelin

Dunno, sounds great to me.

AutoTalent

I think you should a do a muffler delete

iTrader: (1)

use some vibrant racing straight through muffler to smooth out the sound. Removing mufflers will make it worst.

Astolfo

Man that sounds really good. Is it much louder inside?

Mr. J

I think it sounds badass. You should wait a couple weeks and see if it grows on you before changing anything.

How much does it tame the exhaust when you close the valves?

SBH-

sounds incredible !

Guilty

Lol guys!! Come on.

Yes it's 40% louder inside.

I want a sound closer to this:
I know the mustang (yes yikes) has a flat NA v8 crank etc but what can I do to get something closer to that sound?

Don't treat me like I'm crazy!

Guilty

I've never heard about this before. Thanks for your input shardul. AutoTalent was just kidding about the muffler delete. They are the ones that installed my DPs

Turbod cars are just never going to sound like that. If sound is most important, a w204 with straight pipes is what you need.

Guilty

Thanks, and yes I understand that. I'd still like to know if I can install an x-pipe on my car. If yes, any tips on the install? What should I expect? Would it interfere with the Performance Exhaust valves?

thanks and my apologies for the silly questions. i'd like to know as much as I can before butchering my exhaust.

If you already have an H-pipe, an X pipe really won't do anything.

And that's not something you simply just throw on the car. That's exhaust shop work.

You're really over reacting to this. Just chill on it for a few weeks and see if you grow to like it. It sounds good to me and pretty much everyone that's heard it on the video. You might be being a little unfair to it right now. You're definitely being unrealistic if you think you're going to get it to sound ANYTHING like a 5.2L N/A V8 w/ a flatplane crank that's spinning to 9k.

Guilty

Hey sean!

Well I've had it for 2 months now and it doesn't seem to be growing on me

It sounds too rough in my opinion. I keep comparing it to my old M156 CL63 where I replaced the OEM resonator by the one from the CLK63 BS. THAT sounded amazing. I know it's unfair but I can't help it.

I always strive to keep the OEM tone. Right now, it's obvious that I've done something to the exhaust and I feel like it makes it a "rice" car. I just want to tame the sound a little bit, make it a little smoother.

What does everyone think of shardul's suggestion where he said:

Guilty

Yes. I knew that. Obviously I'm not going to weld an x-pipe by myyelf on a jack in my garage

I was going to forward the tips to the shop that'll be performing the work since it'll probably be the first car of its kind where they'll be doing this mod.

It's a (very) expensive alternative, but you should consider downpipes with high-flow cats. Or you can return back to stock and remove the secondary cat (v-banded so you can swap back) - I think that's the best solution for those that want a bit more noise without dealing with the DP install, noise, and smell.

If those options are a no go, then I'd look into an axle back exhaust with OEM DP's.

Guilty

That is indeed a very pricey alternative. I already paid $2800 to have these downpipes installed (including $1k in labor dropping the tranny). Reversing it would be counter productive. I'm also about to spend another 2k to get it retuned to get rid of the check engine light. Overall, I spent over 145k on this car due to an expensive out-of-pocket repair. I can't afford much more

I picked my car up yesterday after having the AWE Track Edition exhaust fitted to the factory dump pipes.

I am extremely happy with the new tone my car now produces.

In 'Park' it rumbles like you would expect a V8 too and no droning on the highway.

sean1.8t

Hmm... My bad on telling you that you were over-reacting then. I didn't know that you had this done months ago. Just thought it was a 'few days old' kind of thing.

I'd suggest searching in your area for a highly reputable muffler shop and explain to them what you want and they might have the best answer believe it or not.

Doesn't necessarily need to be highly reputable either. Sometimes you just need to find a guy that's been working on exhausts for 20+ years.

Shardul is probably right on, but I'm always loathe to do away with AMG mufflers. Millions went into making them sound the way they do (with the rest of the OEM equipment), some part of which you changed. I would go for a complimentary change that retains the AMG mufflers and gets you closer to where you want to be. I would first do the X-pipe, as smoothing out the exhaust sound is the exact function of an X-pipe. An H-pipe IN THEORY serves the same purpose, but it produces that American Muscle Car sound that you think (and I agree) doesn't befit your Mercedes. See more here...http://www.autoanything.com/exhausts...pipe-vs-h-pipe.

My guess is, MB put the H-pipe in to increase the rumble, given the cats in the downpipes. You removed the cats in the downpipes, so now you have too much rumble. I would do an X-pipe first, and only if that didn't work would I touch the AMG back boxes.

Good luck.

Here's the sound if you keep the standard downpipes and remove the rear mufflers:
