Exhaust Set Up for N54

I just wanna see what you guys are running on your 335i or 135i. Want some opinions on what I should do to mine!

Do the PE mod. Basically inside the exhaust you replace the two outer perforated pipes with straight pipes. Do a YouTube search for some inspiration.

Does the pe mod sound better than just removing the mufflers and doing a straight pipe?

Muffler Delete is way too loud like in SoCal cops can’t stand it. PE is a good mod but buy an extra valve for the right side

I don’t think you have an n54 if you have a 335is, you’ll have an n55 engine, the twin scroll turbo. In the mean time, before you get an exagust you can unplug the exhaust vavle in the trunk that will give you a better grumble below 3k rpm.

The 335is was built with the N54 because that was the easiest way to turn up the boost gauge and get more power. BMW have some of the laziest engineers in the business

Hey bro I know my car it’s the last actual twin turbo not twin scroll. The previous owner did it already.
