I made a purchase today... a set of 06 SL 55 mufflers... haha
wish me luck, hope it sounds good....


plus, the downpipes will give me some of the performance with the tune.
maybe, i will hold off on resonators.. we shall see!
The sound definitely changed, but not tremendously. I might just do straight pipe it!
The muffler design is actually crazy, it is straight through with out no restriction, but all that other parts are for insulation only.
I might put these guys for sale soon, they are already pipes to put on w221! Anyone? Lol
