hello everybody. i did some research and couldn't find much on exhaust. i have a 1990 535i with a b&b tri-flow catback exhaust system (came with the car). the exhaust creates a low tone, and is the right amount of loud for me, noticeable but not screaming. my problem is that the exhaust is not throaty, has no vibrato, isn't "burly" enough for me. i know it's a big 6 (3.5L) and has enough motor to make a throaty sound, just not like a v8. i was thinking about removing the resonators, but i'm afriad that will just make it louder and more raspy, not throaty. i also considered putting on dual 50 series flowmasters to some camero tips right under the bumper(so it's not so noticable). i believe that will give me a more throaty sound, and not too loud. i know it's almost a crime to put american muffers on instead of a performance car-specific perfomance exhaust, but i'm just not satisfied with the tone. also considered removing the cat. what kind of exhaust set-up should be done to give me a more throaty sound in your opinion?

***sorry for the paragraph, but it should make for good reseach for others intersted in exhaust options.***
