does anyone make one? I'm not aware of anyone who does. Your only option may be to remove yours (or order a new set) and pound out the cats. Fitment should be perfect!

And if you do it to a new set, you can send them out for ceramic coating before install.

Quick Google search just returned quite a few results - so yes, it looks like they exist.

well how about that! Looks like n63 intake may be selling re-selling the arm product, as they post the exact same gains. And the arm gains posted are on a stage 2 vehicle with a cold air intake and 93 tune, so take all that with a grain of salt. It will be smaller gains for sure without supporting mods and a tune to take advantage of them.

Of course, if the major motivation for the downpipes is aural gratification, then carry on!

As an aside, in googling available products, many suppliers seem not to differentiate between 550 and 650, and even 750 in some cases, and they also don't seem to have a different product for the N63 versus the N63TU. Whether that is because all those cars use exactly the same size downpipe, or because they don't know the difference or care about the difference, will be determined as people start getting into downpipes. Personally, I would be very interested in a proven, ceramic coated downpipe! the stage 2 tunes that are becoming available have some very impressive gains!

Still looking...

I've noticed the same thing cited in first paragraph on some of the tuner's sites. When dyno data is published to the web, it sometimes lacks details about the full scope of mods, whether it is stage 1 or stage II etc.

With respect to ceramic- I have in my hands (in my trunk, actually) ceramic coated AR downpipe. The ceramic option is noted on most vendors' pages. Of course, not having installed it yet I can't provide longevity data, but it looks well done.

I also found the same frustration when looking into applications/cross-compatibility. I think the main factor is laziness- er prioritization based on market size- among vendors. Different pages show compatibility across 5 and 6 platforms, and/or between S63 and N63 or N63TU, and others don't.

In the end, I pinged the manufacturer and while there was a short wait did get a direct response that provided the asked-for part number for my application, which I then took to a retail vendor.

I suppose there's a certain PITA factor to be expected with aspirational Marque...but I don't much like it. And dealing with installers has been a complete joke thus far so I guess I'll be busting the wrenches out.

Maybe it would foster more "real information" if the Commercial classified was more closely managed.

IMHO, there should be a cap on the number of times a thread can be bumped without adding actual information. Listing a product or claiming a sale of some sort and then bumping for months...there's no there, there. Should get maybe three or four bumps and if there hasn't been a reply or inquiry posted by a different party- thread closed.

Since the post you quoted, I determined that the downpipes for the N63 and N63tu are compatible - they are the same between 550 and 650, not sure about 750. I almost purchased the ceramic coated AR downpipes with hi flow cats - they are dreamy . I will probably add them next spring to keep me from getting bored.

Please keep us updated on your install and results!
