I'm looking to install Performance Exhaust on my 128i...how does it sound compared to stock, will I hear a noticeable difference?

It sounds great! You'll never regret going with it.

Find this link below with 2 different users who have installed Magnaflow and Performance exhaust. Give you a picture of both exhausts on the 128i. Enjoy!

if you remove the cats will you be legal and pass emissions testing? if so, I would say its worth it. The CATs and headers are normally what is restrictive. Also, which cats? Does your car have two sets(secondary and primary), and if so, which ones do you want to remove?

the BMW PE for the 128i is just a muffler, probably overpriced, but I've really enjoyed it. I installed myself, and isn't too bad. No welding is required, there's a decent DIY on this forum.
The sound isn't too aggressive, but not soft either, really think the PE should come with sports package.

Secondary cat? Yes
a bit More loud & more power - up 10 hp
Its a bit tricky for 128i due to the placement of the cats, a shop will have to bend or get ~60degree pipes


emission issues shouldn't be a problem. Just warm up the car for 20 min. Also for Ontario, i dont need to do emissions for 2 more years, you probably for 5 more , incase u want headers down the line.

Btw, saw your car again on near at the Finch Go.
