Anybody have or had mbrp race axle back? Just wondering if it’s any louder then npp track mode

It's louder. The race axle back is literally a muffler delete with what looks to be a Helmholtz section.

Will be considerably louder and as said above it's basically a muffler delete with a resonator to control drone. I recommend MBRP stuff from my Mustang but in this case was going to be too loud.

Thanks for the feedback.. I figured it would b a lil louder but wanted to get info if anyone knew if it was significantly louder than npp track mode. People keep thinking npp open means it’s straight pipe but It still loses some through the muffler because of the baffles... I don’t want to waste my money if it isn’t notibly louder, but also live in California so cant go too loud.. thought I would start off with mbrp race axle back and then if I think can go louder I move up to mid pipes... anyways thanks again for the info

I have the MBRP axle back, while driving its WOT or even just cruising there is 0 drone. When you get on it though it sounds amazing in my opinion. I'll be adding E85 and TSP 1 7/8th headers next month so it'll definitely be loud. If you want I can get some sound clips

It’s kinda hard to judge actual sound level through videos. I’ve been able to watch enough videos to know I like the sound, but how loud it actualy would b in person is the hard part... did you have npp before? If so, is the mbrp noticeably a good amount louder than when in trackmode on stock

Agreed, I’ve got the cat back race series. Sounds amazing and after you get headers + Cat delete if you choose that route it’s insanely loud. The cat back is the same price if not cheaper when I looked. If you ever get under your car you’ll a lot of the piping is clamped down restricting a lot of air flow. I’d suggest the cat back personally

My only problem is living in Bay Area California.. if I go too loud I take chance of non fix it ticket.. so I thought I would do the axle back first, if that wasn’t too loud then I would do the rest of cat back... I’m just tryn to confirm if just the axle back alone is any good amount louder than track mode on stock

Lol I just got the race MBRP I hope I didn't go too far. I also have Kooks 1 7\8 LT with catless midpipes. O well, YOLO.

My car did not come with the NPP, my father has NPP on his and with his valves on and us driving next to each other you can't hear his car over mine. I would say it's definitely louder than the stock NPP on track mode. Once I get the headers installed I know it'll definitely be a lot louder.

Thank you.. that’s probly the best scenario possible to answer my question

Yeah I probably should have started with that. I know videos do not do justice but i can do a start up video side by side as well. If I was in the area i'd show you but were a couple thousand miles apart lol

I have an A8, would I need a tune for AFM with this exhaust? I've heard they don't sound great with AFM kicks in. I planned on picking these up from local store this week
