Did they remove the secondary catalytic converters? 10hp/11tq delta for just a muffler is pretty sweet and it looks to be throughout the entire RPM range.

The secondary cats are still on the car. There are two mufflers that were made for the car, not some universal muffler!

This is for the E90's. Mine is a 2009. Don't know if it will fit the E92. I'll have to ask them. As far as price, I Borla won't know until October.

There's a sharp bend in the pipe where in goes into the rear muffler. If they were made for this car, why wasn't it brought in on the forward side of the muffler?? Can you tell me more about how these were custom made for this car?

They used the stock pipe and muffler lay out. The mufflers were made for the car. Borla didn't use universal mufflers and bend pipe to make this system. I am on my way to pick up my car; can't wait! I'll post after I get my car.

The stock pipe and muffler layout has it going in the forward side, and out the rearward side, no bends.. Enjoy the new exhaust, sounds good.

Picked up my car, and it is AWESOME! The system will take about 500 miles to break in completely. It is not too aggressive, but definitely has an exhaust note to it. I can actually feel the power difference. Cruising on the freeway was where it was really noticeable.

As far as any other information fits 2008-12 E90's with the 3.0. As far as price, I was told it will be a few weeks, mid October.

I've had my system on for 1,000 miles and it has finally broken in and there is a sound difference. It is louder, but not too loud. It is also very throaty. Couldn't have asked for anything more re: sound. The fit and finish is superb.
