what kind of dual exhaust system do you guys think would work on my 525?

i think a muffler bypass sounds good on the 525. its cheaper than buying an aftermarket muffler too (assuming you don't get quad tips) keep the resonator but replace the muffler with straight pipes - http://forums.e60.net/index.php?s=&s...dpost&p=294275

What a great pic man! That's gonna help me a lot with my project. I drive a lot. I am happy with my 22 mpg in the city of miami. I was thinking to get a 545 but........ it's a lot of fuel for me! I will try that. Let's see. But, thanks for the pics and the link man. This forum is greattt!
