Maybe I'm in the minority here, but I say skip any "dummy", non-functional parts.

Im with you all the way... I love the quads but would only want if worked.

This is a terrible idea in my opinion. Go for the quad exhaust or stay stock, single pipe. Its like putting an M5 badge on a 525...not cool. again, just my opinion...

+1 personally I wouldnt do a dummy quad. honestly for your 550 I would recommend the RPI exhaust (which we have in stock) for the guaranteed power gains, but its a dual exhaust. if you do want to go quad, Id recommend a custom setup. just my opinion.

Would look weird with smoke coming out of one side

however which ever you choose please do let us know, and of course pics please!!


good luck

yeh or even this

Why do so many ppl seem to be against dummy quads? its an inexpensive way of filling up the quad cutoff on the M5 rear and it makes it easy if you want to go back to stock before selling

+1 not a big deal to me either.....m5 bumper looks way better than the stock and Mtech, so you have to do something to fill in the right side.....

honestly it didn't bother me one bit when i had my dummies.....and not a single person knew anyways.....

but whatever floats your boat....in terms of functionality and "being a poser," with all these people putting on "replica" parts, debadging, M5 parts and such, what's the difference.....

yeah I just got the car few weeks ago so not sure if I'm ready to mod just yet, just gathering ideas on what to mod. I believe I want to do the sprint booster first, then maybe white angel eyes but that about it on the list, well also maybe the quad LOOK without paying the high price of exhaust and sound. if you don't mind, how much did your dummies cost? and where you had it done? picture?
