I need a local shop that I can trust to modify exhaust piping to match this new cat-back system to my existing cat piping sections. It would be nice to see some of the shop's past exhaust work.
thanks!

I just bought this dual 2.5" cat-back system from techtonics.

I don't think anyone in the area has a mandrel bend machine

 

There's one in Suffolk. Let me find out.

 

i know of two that did but both had to stop doing exhaust work because they got caught "altering" smog related components

 

i have'nt heard anyone in the are having a mandrel bender...i could be wrong though. last time i asked around ~1year ago no one had one. gl and post if you do find one

p.s.
bring it over my apt. i got a hammer some jb weld duct tape...DIY! lol

 

Hey, if it comes down to it.. I have a dremel tool. I may not need a shop with a bender. I'll fit the new exhaust and see what all is needed. I might only need to cut a small section out of the pipe, etc. In that case, I only need to find a shop that tig welds. I'm still waiting for http://www.ngpracing.com/ to send me the new exhaust. I bought it through them but was told they would direct ship from techtonics. Now they're saying it's being shipped to them.. then to me.

 

S4 dual side by side's

S4 single 3" all the way back

 

Why do you say that? You must be thinking of the typical dual 2.25". I currently have 2.5 inch APR downpipes (two turbos) merging to single APR 3" cat-back exhaust. The techtonics system is the only dual system available that's 2.5", and it uses straight thru borla mufflers. The APR mufflers have baffles with a bunch of small holes drilled in them.

The reason I'm replacing the apr system is seeing people gain 45hp with exhaust dumps, while people with other systems don't gain near as much. That tells me the apr mufflers must be restrictive. Not to mention, the cross section area of single 3" pipe is 7 square inches, while dual 2.5" pipes have a total cross sectional area of 9.81 square inches.
