[s-cars] [Es2] S2 Muffler for tight fit/clearance

[Matt twentyV]

Ben, I have a 3" system from 2Bennett that is just a single rear muffler and has a nicely balanced sound.  OTOH, I have an 034 3" system on our urS6, it has a center resonator and is much louder.

It must be the selection of the rear muffler.  I'll try to see if there are any vendor markings on the coupes 2B muffler tonight.  If you are contemplating cutting and welding, you might consider just replacing the rear box.

BTW, I found the overall fitment of the 2B system on the coupe to be much better than the 034 system on the urS6.  The 2B system fits neatly up into the underbody and doesn't rub anywhere.
