Josh / Eric / Anyone who can...any way to get some pictures of the cutout from the underside? I'm really liking the template...makes it look very do-able. How did you guys smooth out the burrs / make it all look smooth? Does the cutout edge need to be painted, or does it disappear once the tips are installed?

Just need to know if it's the right size in the right place.

Also, has anyone tried this exhaust with a catted downpipe? I may get a stage 2 tune at some point, which requires a high-flow downpipe, but I wouldn't want to ruin the sound that this exhaust was designed to have.

And how aggressive is the sound? I'm looking for something that's subtly noticeable. Basically, I don't want it to sound like I modded my car with a loud exhaust, I want it to sound like it came with an aggressive exhaust note from the factory.

Josh/AWE Could you follow up?

Dark: I haven't experienced our system on a DP-equipped vehicle. The note this system provides would not give you the aforementioned "loud" presentation. It's very controlled and depends on the throttle input. Your aforementioned idea of the diffuser swap should happen quite smoothly seeing you're basically all set up to do so.

I looked under every rock to see if I had any images from directly underneath, but I don't unfortunately. Take a peek at the install guide right here, I think it will help give you a visual for your questions.

Is this what you're looking for?



As far as noise, for me, the AWE exuast is perfect. The only complaint that I have is the same complaint that I have with every turbocharged BMW combined with a sport exhaust: at cold start it's a touch annoying. When the wastegates are cycling like mad, for the first 20-30 seconds of a cold start, Turbo BMWs sound like a wildebeest fart. The same is true with the shop 135i (Catless DP, Factory 1 Series M Couple quad exhaust with center cat). It sounds like a$$ at first then smooths out to an awesome sound.

this is easily the nicest quad setup for the F30. If i had the money I'd be all over this...maybe when the price drops

I have this exhaust and it's absolutely wonderful

Everyone seems to love the exhaust so much with their factory cat. I'm a bit worried with my catless downpipe...
