Exhaust quote: Good or Bad?

Okay guys, I just got back from the exhaust shop. He gave me a quote and I wanted to run it by you guys to get input from experts. He quoted 265.85 to cut from a few inches before the 3rd cat back off, and put an x-pipe there with two 2" pipes running through the stock tunnel in the tank and around the pumpkin, one pipe on each side to the back to weld in two mufflers( I provide those). He said he'd need two 15' lengths of pipe, $39/each, he'd make his own x-pipe. An example I was shown looked like 4 90 degree bends cut and welded together, and aluminized pipe coated with some heat paint or something like that. He says 15$ for misc hangers and the rest for labor. Bring it in the morning and he'd have it ready by noon. He also said i'd need to find mufflers that have a center output and offset output and that the output pipe would necessitate having the exhaust hang down at an angle on each side toward the center. He said that two inch pipe is all that would fit through the tank tunnel without rubbing. Now the plans for this car are to rebuild the block with forged everything, P&P'd NPI heads with custom cams, and the 9# AED kit ( unless better and more economical(read: cheaper) kits can be suggested). Will two 2" pipes support the flow I need without causing extreme bottlenecking/backpressure or should i try to convince him to go bigger. My mechanic says 2.5 inch is too big and will kill low end but later on (money providing) i plan to grab a set of kooks 2.5" headers and custom downpipes with aftermarket cats. Should I go with this deal or what? Any input would be great. Thx in advance

good price for the work, but I would use a Dr. Gas X pipe, and 2.25 pipe after the X

i think thats a decent price...but too small for your future plans. you'd need AT LEAST 2.25 if not 2.5 to let it breathe properly. people have done 2.5" just fine..he's just intimidated

2.5 all the way with 2 40 series flowmasters up front

It's so hard to find good help these days. It took me a week to convience a shop that this exhaust could be done.
In fact to have the same put on my cat I had to bring in the bird to prove to them it could be done.

My exhaust guy charged me $325 for 2.5" pipes from the first cats back to the mufflers (true duals, no x pipe)... he hung Borla muffler back where the stock ones are, only at a 45 degree angle to keep the pipe straighter... i lucked out and got the Borlas for the same price as dynomax the whole job was $600...
