New Exhaust for my Duster?
It'll say "Edelbrock Performer" right on it or what ever manufacturer it is except stock OE.
Learn to weld yourself. Your first expense is the welder. I grabed mine from Sears and started to weld after reading the booklet and with a few scrap meatl things around, started to learn.
IF it looks like fidos *** when your done, that is OK. Just get the metal hot and make sure theres good penatration of the welding material and the two parts your joing together.
Worst casue....you do it again. LEarn, save money in the long run, maybe.... charge your freinds cheap fee's for more welding material.
Lots-o-places make headers, but the best ones to purchase and use are very expensive while the $99 - $159 dollor units are all the same for the most part and they all stink with 3 out of 4 tubes on the drivers side going under the steering linkage and THEY WILL get dented and flattened out.
Hooker, Dyno Max, Headman, Summit, The list is long.
