This exhaust is a must for all the free flow your turbos deserve. I have a set of stage 4 turbos and this was the last piece of the puzzle for my exhaust setup. Really gives the car an aggressive tone and so much more fun to drive. Highly recommend.

I have a set of catless downpipes and this set up and my 135i sounds amazing!!!!!!

Installed on a 2009 E88 BMW Convertible and it bolted up easily. Remove the chassis stiffening cross brace and it is a direct replacement on the 135i. Sound is throaty, yet doesn't drone on the highway or off load. There are two places that could use relief as they hit the chassis in two fixed spots, however, the chassis brace holds it tight so there is no banging under the car. Tips line up perfectly in the bumper recess and they look great on the car. Again; great sound when you want it, not overly loud when you don't. Beautifully made.

It’s what I wanted sounds good, loud! Love it

All the weld look quality and provides a great bolt on delete option
