Went to get estimates on exhaust
Yes, it's quite shocking, isn't it! The only guy in town who would do it quoted me $700, and he said at that price he would do it in his spare time (he originally wanted $800).
Welding is not necessary, but I chose to weld mine. I got blinded by T304 glitter, and went with the Pypes system. As someone on the board aptly put it, it's the stuff new curse words come from. I haven't used the Summit / Jegs kit, but my extensive research showed it was not bad at all to install. As for the included mufflers with that kit, they are SO cheap it's almost silly NOT to get them, if you aren't sure. At the time I checked, I think it was only $20.00 more for the pair. Then again, Thrush welded are pretty cheap, and people seem to love those.
There are several threads here with sound bites of different mufflers. I find FABO's implementation of the normally good vBulletin search feature to be infuriating, so good luck.
