i have bought a magnaflow muffler for my ss/sc, its a 2.5 in and 2.5 out, i want to get the stock exhaust cut where it slims down to 2.25in and replace it with a 2.5 pipe from there and over the axel to the mufflier. Does anyoen know these dimensions of the pipe lenghts and bend angles so i can have my brother inlaw weld and bend pipe at his shop to complete this.

if anyone can help out that would be sweet as i dont care to pay midas 200 for this

 

I had a guy at a muffler shop quote me 140 bucks for a entire custom cat back....

He only charged me 40 to have my dp welded up, so no more than 60 or so to have some pipes welded in... Find a local muffler shop...
