Not bad. I'd live to see a straight pipe video.

VividRacing

Hopefully someone does it!

What do you guys mean straight pipe video?

VividRacing

I guess we're kind of assuming this video is just a new axle back system. It would likely be much louder if they were aftermarket headers.

Just sounds a bit louder, deeper and tamed compare to stock. Not the lethal monstrosity music we get from the LTH

C-63AMG

What's LTH?

whoadude

long tube headers

C-63AMG

Thanks bud - wtf are they

VividRacing

The part of the exhaust system between the head of the motor and the mufflers pretty much.

Some companies have midpipes and xpipes that go in between the headers and muffler sections but it all depends on the manufacture

Thanks Vivid, Thanks cool,

I've removed my secondary cats and replaced with an X pipe and I've removed my resonators and replaced with straight pipes but still not happy.

Will remove the X pipe and replace with straight pipes and hopefully will stick with that.

Are these headers expensive?

VividRacing

I'll shoot you a PM with special pricing on our headers!

Removing the xpipe will cause it to sound a lot more uneven if that's the sound you're looking for but you will lose a bit of power

C-63AMG

So are headers the things that come off the engine or are they the pipes between the primary cats and the tips? Bit confused. I read that link and seems to be the things that come off the engine but not sure

VividRacing

it is the part that comes off the engine, I'm sending you a PM with a link to some pictures!

C-63AMG

I know removing the xpipe will cause maybe 5hp loss from what I've read but when I did the staight pipe resonator delete it was loud but only at certain revs and at certain speeds and I wanted louder.

So I did the secondary cat delete with an X pipe and that kind of gave it a more constant loudness but it was more refined although at all revs instead of just at certain revs. Now I want pure LOUD so have been recommended to remove the xpipe and replace it with straight pipes.

C-63AMG

Thanks Vivid

VividRacing

Go with our headers, you will get the PURE LOUD sound you are looking for!

Check out my YT channel. I don't actually "broadcast" anything so most of my videos are of my exhaust setup.

Lol headers are expensive but if LOUD is what you want then go for it! and just add a custom made H pipe on the resonator area. Try to make the H pipe connecting pipe 1.75" only. This set up will probably be so loud you ll hear the AMG roar in your sleeps hahaha

natman316

that sounds good but not as good as stock imo...

that diffuser though....only if it were around 1500 wink wink

Sorry quick question...are you saying if you had LTHs on your car and then add an H-pipe this would be louder than just the LTHs? Sorry I'm also new to this. I thought the H-pipe would calm it down a little....Any info would be greatly appreciated. Thanks for your time.

Finally some questions i have a little insight on!

Okay guys, from personal experience, straight pipes/secondaries and straight pipe/resonators will sound cheap. LTH and stock exhaust will sound much louder than stock.

Most people with LTH replace the secondaries with an x pipe to tame it a little bit more since most LTH remove the primary cats also. It is CRAZY loud, and if you straight pipe the whole way, it'll be obnoxiously monstrous. Not for everyone, but it will get you some unwanted attention and not the good kind. Cold starts will wake up anyone living within 400 feet of you haha. If you plan on deleting the primary cats, a tune will be needed to disengage the CEL. It'll also give you a nice boost of 16-18 Hp i believe. LTH and a tune are one of the biggest power gainers for our cars.
This is a members c63 ( edition1 ) with LTH vs a p31 c63. So you can get an idea of how much power you will gain.

My current Set up is Kleeman headers, *not long tube*, no primary cats, no secondaries ( replaced with straight pipes) and my resonators have a custom H pipe with 1" piping connecting the two banks. Sounds like a corvette with cams lol. I'll put up a video in a couple hours.

If you don't want to go the obnoxious route, i'd just replace the secondaries with straight pipes and an H pipe in place of the resonators. You will want an X or H pipe to connect the banks so you don't lose much back pressure an equal out both banks.

Hp gains/losses with secondaries and resonators will, i have to emphasis this because it's been such a big debate *** WILL NOT BE NOTICEABLE NO MATTER WHAT SET UP YOU CHOOSE*** straight pipes or x pipes, it might feel smoother but the gains/losses are so minimal it wont do squat on the track or road.

On topic: Nice exhaust, but not for me. I like the AMG rawness the c63 has, this tames it too much.

MagasC63

Wow thank you for that info...I appreciate your time and input. Cheers
