Anyone have catless downpipes paired with AA single midpipe? Or thoughts on this setup?

I'd imagine this to sound almost identical to Valvetronic + MAD dps (the midpipes sound almost identical).

My guess, it will be too loud for me. Go for the catless downpipe first. If it’s not loud enough, then you can install the midpipe.

The AWE is money, and I love how it integrates with the drive modes so you can easily run it quiet if needed

I would honestly say do the opposite first, because the single midpipe completely changes the tone of the exhaust. You should first decide if you like the tone, then perhaps make it louder. At least IMO

The only issue which is basically why we get exhausts, it doesn't sound as good as AWE and I guess eisenmann race. Too much rasp and crackling, the turbo back video is insanely loud. My apologies when you search G80 on fabspeed.com it still showed the F80 exhaust and I thought it was $4,000 for G80.Even $4,700 isn't bad for a good product but if AWE with 2nd cat delete gets us there then that's even better. I'm just annoyed that I wouldn't be able to jack up my car and do it in my own driveway, but fabspeed and eisenmann you could.

This one is pretty good if you want more sound!

I have a video of a guy here that has Mad catless Downpipes on the AA single midpipe. Perfect angle on the car when he accelerated. You can hear it under load and going through a couple gears. However I do not have the video uploaded anywhere lol. I'll throw it on my Instagram and send you the link.

The car in video has Mad Catless Downpipes with AA single midpipe and stock rear axle back.

Love it! Will high flow catted DP give similar result? Don't want to deal with CEL.

No idea what the catted downpipes sound like. I will be doing this exact setup except with the resonated version of the AA single midpipe. And I'll be unlocking the DME and won't have to deal with check engine lights.

Good plan

[anakratis]

Need MAD to come out with catted downpipes ASAP

This is absolutely awesome but too loud for me haha. I wonder how the 400 cell AA downpipes would sound like...

You guys realize that catless downpipe on today's cars may cause overboost and cause the throttle valve to partially shut and pull timing? This is Inherent to small quick spooling turbos of today where as years ago larger turbos were used thus more lag.

It's interesting that many years ago, power gains were mostly discussed when talking about downpipes and exhausts. But now it's almost all about sound.

Not when you unlock the DME and go for a full tune.

Are you speaking from actual experience on this platform? Because lots of folks here say that the overboosting and throttle closure settles out after the car has had a chance to adapt. Of course the flash tune will take care of it immediately.

Small quick spooling turbos are not really new, unless you're comparing to 20 years ago. And if you want to make big power then you still want to remove restriction in the exhaust. Just need some sort of tune because the ECU is too smart these days and tries to make consistent power.

Can you show me where they actually made decent power without any tune after adaptation? Even earlier versions of tunes have some difficulty tuning this out. I remember I had this same exact issue with several newer turbocharged cars, even with a tune.

I remember a catless downpipe on my old evo ix's, wrx, sr20det, srt4, etc. there was at least 20-30 hp gain with quicker spool and no issues with overboosting, unless I installed a bleeder valve or an electronic boost controller and went too aggressive. But that was mitigated by mechanical internal adjustable wastgates whereas todays cars are electronically controlled.

Of course, but I was talking stock tune. And most ppl aren't willing to send their DME to Russia.

Agreed, I say go VT Midpipe + Valve Controller first, then consider DPs.

That is what I have/had but with VV mid's and didn't like it. Waiting on catted dp's to arrive. May even add a resonator to the mid pipe to calm things down more.
