Very nice! I have the same ones. Fitment was perfect to give you the heads up. No rust either

Just to let you know these are "very similar" to the Macht Schnell downpipes (if you catch my drift)

Seems to me that these BMS pipes are the best bang for the buck pipes and im sure they will hold up just fine. Definitely my next power adder in addition to my JB4 and Meth set up

I think BMS said they were not going to do a catted version.

Catted DPs are overrated....you can still get CEL's and the dealer is still going to bust your balls if they find them during a warranty issue. C@tlless is the way to go....more power as well.

I think the only reason people want a catted version is for emissions purposes in some states or to reduce the smell/noise/raspy tones.

I agree the catted versions should be avoided, they tend to fail over-time, and really defeat the purpose of replacing the downpipes, which is to remove the biggest restriction, the cats.

I feel they are thinking of emissions primarily, but don't realize they can fail with the catted DPs....and yes, the main cats are huge restrictions.

You (Jeff) know this, but (for others) if you leave the secondary cats in place the rasp really isn't present and the smell is minimal.

Yeah please keep me posted and please note what to watch out for!
I've seen some instruction videos and you gotta move aside steering rods and stuff which I really don't want me messing around with...

Thanks in advance!

That reminds me of a couple years ago when I was still somewhat into the Audi scene and I was helping my brother diagnose an issue with his B5 A4 QT.He was having low boost issues and blowing white smoke. Pulled the turbo several times and found nothing wrong with it. It was a brand new ATP turbo that we installed a couple thousand miles prior to the issues. We checked several other things including changing injectors etc. and could not diagnose the issue. Even enlisted the help of some of his local friends who were supposed to Audi gurus. I mentioned to them that I thought the HFC may be the problem and they all dismissed me. Well after pulling the turbo a final time we decided to remove the HFC and inspect it. Upon a visual inspection we found the honey comb material completely FUBARD. It pretty much became dislodged and clogged the exhaust path and melted. This caused the back pressure which ion turn resulted in low boost and seals blowing oil.

I'm going to have to bookmark these bms dp. I love the quality of the tig welds but I'm not ready to go catless just yet bc of the smell and I'm also still under warranty. I have heard allegedly thought that with a quality protune you can minimize the obnoxious gasses.
