On my c63s with a tune and no DPs vs a tune WITH DPs, other than spool and sound are there REAL quantifiable gains with these? Like 30WHP? Or is it more like 10 and a lot of sound lol?

i have tune and downpipes and I don't think the downpipes make significantly more power, I got them both at the same time, but looking at dyno graphs it is really more of a sound thing. But totally worth it for that.

Sanch

Mainly sound

I think response to as you can hear the turbos spool as aftermarket downpipes are free flowing.

DaveS550

Darn /: so they don't provide a big power increase? For $3,000 basically I'll pass...

brad65ford

I've been on the fence myself for a high flow catted dp but they are just under 2k. With a performance exhaust most would agree it makes the exhaust sound like crap. Mind you the other after market exhausts other there do sound very good with dp's. Personally after looking at Eurocharged recent post about turbo upgrades for 4k its a no brainer for increase in power versus dp's imho.

DaveS550

You mean downpipes sound bad with the Mercedes AMG performance exhaust? Because my car has that exhaust...

AutoTalent

There definitely is an increase in power in addition to the sound. You can do the FI catless DPs for $1250 shipped which we have in stock

Night and and day for me. Plus sound is perfect

brad65ford

this is the consensus sounds like a diesel truck at idle lol. Once DP'd, personally believe Akrapovic sounds the best though they carry a high price range. Haven't heard to many catted down pipe's with stock performance exhaust, assuming it wouldn't be to bad.

jkob5

would have to disagree. Idle sounds great on my catless DP with stock amg exhaust. definitely subjective though.

brad65ford

Totally agree sound is subjective. Though I don't think you'll find someone that doesn't like the akrapovic exhaust with dp's ;-)

So I pulled the trigger today at Eurocharged Orlando for some Armytrix DPs and their tune

Going to be installed and flashed on 8/9!!

I had dp tune and exhaust done 2 weeks ago. The power difference is substantial. The sound is also much better in my opinion. I spent about 8500 total and feel it was well worth the money.
There is a small odor without the cats but not bad unless in a confined space.

black63s

Did you do the armytrix system?

AMG 17GT

Not sure what that sounds like exactly. My subjectivity says not good at all.

G8rh8rtampa

No I had mine done custom by c2design in Tampa. Chris does great work. www.c2dusa.com

brad65ford

Does sounds a little odd. But in this video they sounds good.

jkob5

yeah the sound doesn't sound true to ear, especially the fist part where the camera is below the car. It sounds closer to real life when I pick up the camera, even then my phone cannot get a good recording. I didn't help anything by filming it in a garage either. I recorded some driving sounds, but all the gopro picked up was wind noise.
