128 PE to 135i N55 engine
Good morning,
Wondering if anybody here installed a 128i PE to a 135i N55 engine. How was it? Thank you

my recommendation is to do a secondary cat delete and upgrade the axle-back. EG. you can do a PE mod to your current muffler, or replace with something like a Magnaflow which is what I did. note that an axle-back upgrade or a secondary cat delete without each other wont be that loud. this is what my setup sounds like (magnaflow muffler + secondary cat delete) note that the flyby/takeoff video is much louder in person, but this is what you can expect your car to sound like more or less. |

It can be done, but be aware that the exhaust pipe diameter is smaller on a 128i than the 135i. So you will be making your flow more restrictive.
