Resonators for OEM M5 Exhaust

747flyboy · 02-07-2013, 11:23 AM

Guys, I need a serious advise....I installed OEM M5 exhaust to 2011 550i F10 M package with custom made free flow Exhaust Manifold (downpipes) matched with a software.
The power gains and band are immense and so is the sound.
The noise is a Love or hate relationship.
I am seeking an advise to what to do to tone the sound level down a bit..I donnot want to basterise the OEM exhaust....Therefore my best option seems to be couple resonators within the Xpipe section. I would greatly appreciate if you guys can tell me what are the best resonators money can buy to match with this beautiful 3" OEM M5 exhaust or any other ideas to quite down this beast.

Do you have an M5 badge on the car?

I dont.....its a 550i M package with a quad round M5 OEM exhaust that makes a lot of noise and power.

I'm curious as to why you didn't look into an aftermarket exhaust? I haven't priced the stock BMW M5 exhaust system, but I'd have to guess it's more expensive than many of the replacements? Ahh, it just dawned on me that you probably got the stock system from an M5 owner who replaced his? I'd be interested in a sound clip from your car with the de-cated downpipes, something I've thought of doing with my stock exhaust. I don't have any resonator suggestions, other than to call one of the aftermarket exhaust companies for their input.

Used their products on a few cars and a JK Jeep. Very good quality and a good vendor. Well known with the foreign turbo car crowd (Subaru WRX, Honda, etc.).
