I went to two exhaust shops to find out about making custom piping. I have a 92 lude si 4ws. One wanted $120 and one wanted $160, this is just for mandrel bent catback piping (bpipe). How is this price? I am in SoCal if antyone can recomend a shop. Also, the guy for $120 said he will use aluminium, is this best material to use?

BTW the piping is 2.25"

 

around here in ND i got an estimate for my hatch crush bent 2.25 for 105 goes on tuesday or wednes day. but those seem like decent prices. Hopefully they'll do a good job for you
later
