    anything will sound good on your 3.1, seriously. even straight piped those things sound pretty good. we got ripped off with the crappy 3.8 exhaust note.

    you can fit pretty much any muffler you want so long as the inlet and outlet sizing is correct.

    or tthis guy

    MagnaFlow Performance Muffler 10434: eBay Motors (item 390195567166 end time May-20-10 02:09:55 PDT)

    I agree the local shop sometimes sells stuffs better than the branded ones but installation and fixing charges are not that reasonable, even after discounts.
