i just ordered mine w very attractive price for E rear SPORT muffler and E center pipe set up.
Now i m already thinking abt. changing it to E Race muffler...but prefer 4x102mm round tips more...because my mechanic has told me that its rather quite after their installation.
but matter of fact, i hav not driven or heard of it yet since my car is still at the garage for installing a new hood and i m only just back from a long trip, but from the comment made by the installer, 1st impression is rather surprisingly quite for this setup (E sport rear muffler +center pipe), so i m a bit disappointed to hear that becoz i thought this set up should be as loud as the E race rear muffler. Of course i will listen to it myself to confirm.
