I'm looking to grab a set of LTHs, however, is ther esomebody who's had a setup that doesn't drone?

Does LTH with OEM Catback Drone? I've heard it does and doesn't, but, it's also ridiculously loud IIRC, no?

Thanks in Advance!

It's loud on cold starts. But when it warms up, it's a tad louder than stock and with an X-pipe, it should be close to drone-free with the OEM catback. Make sure you have a resonator for the least drone. The best headers are MBH.

I am Jeff

I have zero drone with my MHP/ARH LT headers with 200 cel cats and xpipe setup. IMHO, Best sounding setup that I've heard of so far. My 18 month child has no problem sleeping in the car while I'm driving.

Is there a real difference between the MHP and the MBH Headers?

That's what I was looking at. Headers w/ 200CEL Cats w/ X-Pipe.

How is the start-up on your vehicle? Is it as loud as the other ones too? The initial "Bark"?

Phil Chow

If I rock MBH Headers with the 200CEL Cats & X-Pipe, do they delete the Resonator? They shouldn't right?

The Resonator is further back?

So your setup is LT's>200 cell cats>x pipe >stock mufflers?

Kriston

if your running stock mufflers, keep your resonator in place. Its loud with the stock catback. Best solution is to run an aftermarket catback IE: Eisenmann or Akrapovic, which are known to tone the raspiness of the LTH's down.


Search my threads I have posted videos of how this sounds on my car. and entire video in the Video section as well.

I run the same setup as Jeff. Sounds awesome when you feed it the fuel, almost quiet as stock cruising. Been on a few two thousand mile trips, ZERO drone.
Cold starts have some anger to them lol, but settles down quickly to a nice rumble..

I have catless LTH and catless X-pipe with stock resonators and mufflers. Sounds great under load and acceleration with zero drone on highway until about 80mph where you'll hear a bit of it.

Phil Chow

The Akrapovic seems to change the sound of the AMG too much. Not to mention the crazy price, haha.

I plan on keeping the stock resonator and everything in if I get the LTH. Did you run your Eisenmann with LTHs?

Are you or Jeff able to take a video of any chance? That's good to hear there's no drone though. I've heard it both ways, where some people say it drones, and some people say it doesn't.

Is the bark during a cold start just the initial one? And then it quiets down as the car warms up, correct?

I assume that it'd be even quieter, if I run HFCs too right? I need HFCs to pass my Inspections here anyways.

Do you have any drone in the 50MPH range? I find most cars that I've had, it drones right around like the 2,000 - 2,500 RPM Range, can anybody confirm that there's no drone within that range?

Thanks again for everybody's help/assistance!

Phil Chow

Anybody else able to chime in?

my set up is the MBH lth, all cats deleted, resonator deleted, mbh x pipe and stock mufflers, no drone and IMO its still relatively quiet under 2500 rpm
