:oops: thot about that fuel cell, but I had already put a new tank in w/ dual pick ups out the back of it, thus ending my tailpipe dreams. remains to be seen how loud it`s going to be. put two 3.5" bullet roundy round mufflers -w/ a 3.5 spiral core tack welded 1/2 in and 1/2 out of each one. dunno, hope it`s not deafening----bob
