DME Tune and SSR Downpipes - 20k miles

No issues so far. No CEL other than a recall for the gas tank sensor.

Stage 1 or stage 2?

Stage 2. I think you have to run stage 2 with catless downpipes but I could be wrong

Do you also have intakes? Have you dyno'd to see what your gains are?

No I did not get intakes. They're more just for sound really. I haven't done a dyno yet

I also have a '19 M5C.

I ran the BPM Stage 1 w/AWE catback Switchpath for ~6000 miles - no issues or problem.

I recently installed (~2000 miles) the AA High-flow catted primary DP + AA catless secondaries, Project Gamma front mount intakes, and BPM Stage 2…holy $hit what a difference.

Sound wise - its deeper and more aggressive but reasonably tame unless exhaust valves are open or WOT. Intakes make no difference for power, but the jet engine sound is intoxicating.

Haven't dyno'd yet but I just purchased a draggy so we'll see 🤞

As far as Stage 1/2, you can run Stage 1 with or without changing DPs, but you definitely need to run high-flow catted or catless DPs for Stage 2 to account for increased boost.

Sounds like an amazing setup. How do you like the project gamma intakes so far

I think they're great, especially for the price point…I know some are concerned with water but I haven't had any issues nor do I think I will. A lot of folks have strong opinions about which intake is best, and I'm sure there are differences, but for the 90% of us who aren't chasing big numbers or those who really care about carbon fiber under the hood, I don't think it really matters. But what do I know 🤷*♂️

How is the quality on the AA downpipes because I was thinking about a set of them myself?

They are 400 cell, which is more restrictive. For that kind of money, I’d buy Fabspeed or Keller that use HJS 200 cell cats. HJS are the best but also the most expensive cats. There is are a couple of others that may have generic 200 or 300 cell metallic core cats that would be good alternatives to AA. One is Redstar. The other is Evolution Raceworks.

Definitely a variety of options out there…I can't comment on which is better or why, but I went with AA because of a hookup and I ran some AA parts in my F82. I also went with AA because they guarantee no CEL - could simply be marketing but I haven't had one so that's a plus for me (yes, I could have a CEL coded out but I'd prefer not to).

As far as cat cell#, I'm not sure it makes too much difference for the majority of us….with 400 cell supporting up to 850hp it was good enough for me.

Overall sound impression is that its marginally louder with valves open or at WOT but that's about it…biggest benefit IMO is allowing a Stage 2 tune.

I have definitely been considering the Redstars but not the ERs because of a lot of issues that I’ve read about the fitment with them and if anyone else has any feedback about Redstar I would love to know!

How did you like the Awe switchpath before adding Dps. Also comparing with Comp exhaust.

Redstar also uses HJS cats (not an alternative). High quality materials, welds, etc. customer service is amazing. Can't imagine any other brand being better.

[pbonsalb]

If Redstar uses HJS then the top choices and also top dollar would be Fabspeed, Redstar and Keller since all use HJS. I have not compared prices on all 3 but would guess all are about $4k.

You still running this? About to buy a pre LCI with a very similar setup and need it as my daily. Therefore want to ensure some reliability. Curious if you could shed some light on how things have gone for you
