i live in lafayette, ca....about 15 miles from san ramon, near walnut creek and pleasant hill. I own a 1990 bmw 535i. Would this exhaust system work with my car? Would there be any difference if i put in the M5 exhaust into my 535i? I want it to be a little louder and a little extra power wouldnt hurt either. How does the M5 exhaust sound in comparison to the stock 535i exhaust system? -Zoeb wcplaya9@home.com 1990 535i 5-speed Sharked
