i need to know how broke im gonna be

For putting in a new muffler...$60 is what my brother paid for his install. But if a full cat-back system...will be around $100 or so.

$5 a weld.

Its cheaper to have them built it , then YOU install it yourself.

i got all of my parts in today so im getting it installed soon, i got the 2 90* mandrel bends, how many welds will there be?

I got my exhaust done for $160 at a no name shop but I had to provide the flex pipe and used my old cat. this was from the manifold back
