As I said, yes, but I believe only on my car.

chubbs - Installation was "ballpark" from what I have seen here so no issue with that, but my overall installation was more complex than normal because I wanted cats. Call Richard at Dyno-Comp...I'd rather he discuss pricing with you.

BerBer63

There's no such thing as ballpark....it been as low as 600 to as high as 1600. Fair enough tho, glad your enjoying it.

bhamg

Sorry, there is such a thing as ballpark. You were unfortunately quoted $1,600, I personally have never seen labor quoted on this job as over $1k...so throwing away the outlier makes ballpark between $600 and $1k...YMMV.

Why did you want cats? Do you think you will be inspected and/or were you concerned about noise?

bhamg

It was two things - noise control (I wanted to eliminate the chance of any drone at highway cruising speeds) and (not wanting to get on a high horse here, but...) being socially responsible, especially here in SoCal.

Even Money

Very nice. I need to move to the SW..one to find better weather and second to be closer to the shops and parts that I would like to visit. Maybe it's time to drive to Scottsdale then back up the pac coast highway?

Back to the headers, would there be any benefit to replacing the stock resonators/h tube with something similar, but w/ more flow and sound suppression, assuming no cats? And would using a header wrap do anything to improve the heat retention?

Again, great headers and results!

Even Money

One more...is there a deal with the headers and this custome renntech tune?

bhamg

EM - Thanks. What I know about the MBH headers is specific to my own application (with cats). The exhaust note under a wide range of throttle application ended up being about as perfect for me as I could possibly have expected but I wanted it somewhat on the quiet side. Perhaps Hooley can jump in here...or maybe you should call him and/or Richard and see what they think. They must have some ideas but I'm not sure what is out there that would provide both more power and additional sound suppression. I recall a prior discussion about coating SS headers with no particular consensus reached...personally there is no way I'd wrap these, but that's just me. I will say this - when I throw the hood open after a hot drive the engine bay seems to cool down faster than before.

bhamg

Here is how it was done on my car. (Sorry about the iPhone photos). No one actually knew exactly where the cats would be going until the headers went on...then test pipes were fitted in place of the cats for dyno testing and tuning. The cats replaced the test pipes at the end for more dyno runs and I drove away with the cats installed. The (removable) CA-legal cats were installed where you see the test pipes in the first photo. The second photo shows the compact size of the new cats vs the OE cats. Hope that helps.

edit - The site is not allowing the upload of these photos so here they are on another thread. (Post #43).

fantastic results, is it me or the exhaust tips sticks out a lot more?

I was thinking about that the other day. I took a cruise up to San Gabriel canyon (wanted to take angeles crest hwy but its been closed for a while) with my GF last weekend, and thought to myself how awesome it would be if a bunch of c63's and various AMG's just rolled up through the canyons.

Brian GT PRO

Looks like they did a great job for you! I was confused about the use of the cats, now I get it, you now have highflow aftermarket cats that slide on after the merge collector. Very nice, kuddos.

bhamg

Nope. still the same as before, but your comment reminds me of this from rarfinancial:

bhamg

Some day this summer we'll do it.

bhamg

Thanks Brian! One small correction...I don't believe there is any such thing as a "high-flow CA-legal" cat. They look like they might be but they are not. As I understand it, in order to be CA-certified, the cat must be manufactured to a completely different standard (additional precious metal washes etc.) so that it is more efficient - cleaner - as well as longer lasting. They look very cool installed but I am still down ~ 20WHP with them on.

bhamg

Give Richard at Dyno-Comp a call. If you end up doing it be sure to pass through Las Vegas on your way back!

Sincity

Yeah.....we'll hear him passing through.

Bhamg: How long is that CAT? Vibrant makes a slick SS resonator that is 12" long from end-to-end.

bhamg

Interesting...I just checked it out, good find...I think the cat is maybe 9-10" in length.

How is the Fit and finish of the MBH LTH's? Did the installation go smoothly?

Raleighc63

Do you have any pics of the headers?

MBH motorsports

With long tube headers, weather it be for the 55's or the 63's or 500's. Installation is strait forward. You have to disconnect the the steering shaft (1 bolt). Once that is out the headers just slide into place. Bolt the header down and reconnect the steering shaft.

All tubes are capped and purge welded. Then finished with our Scoth-Brite finish. Or by request a matte metal finish.

I personally Inspect every set of headers that is made. I make sure the header flanges are cleaned up and ported out.

_AMG_

Sounds pretty straight forward.
Saw a picture of your LTH's, the quality and welds look top notch.
AND THE SOUND...

2010c63amg

how much is the header tune combo?

MBH motorsports

I've got a bunch of pics from fabrication to final product. Some maybe of the CLS/E63, but the design is basically the same. I will PM you some more pics if you like? However if one looks a bit different its because its the other 63 model. It should give you a full grasp as to what goes into these headers from beginning to end.
