I'm getting a custom piping from a muffler shop. I have gotten 2" DC 4-1 headers, 2.25" carsound cat, 2.25" 22" resonator, n 2.25 oval magnaflow muffler. My question is do i need any mendrel bend before i bring it to the shop to get them all installed/welded on? If so how many do i need and what kind of angle do i need? 180/45/90? Would it be better to have these? thanks alot guys :D i'll let u updated once done.

 

Do you guys know how much muffler shops usually charge to do the custom piping and install the pieces and welding them together?

 

bring your stuff to the shop and they bend the pipe for you....i took two mufflers and a cat to a place called tuffy and they did single pipe to a Y pipe and dual exhaust, bent all the pipe over the LCA's for $100
