Does anyone know where i can buy a big, preferably stainless dump pipe from the stock twin turbos? Would like one without the provision fro the stock wastegate and egbv, so just 2 turbine outlets into one to replace the first cat.

Anyone seen any around the net?

Cheers - Gene

Get one fabbed up. Take it to a shop, show em what you want, where you want it to dump to, etc and let them at it.

Custom will definitely be cheaper. Some companies have the nerve to charge 400-500 bones for a straightforward pipe that dumps under the car.....actually, the same goes for all the other exhaust parts like mufflers and downpipes, etc... hmmm

Are you going side-exit?

i made mine for $50 out of 304ss... but i knew a welder/fab guy... still 150 should get the job done


-cardboard copy of the top of your downpipe's flange.......free

-8"x8"x3/8" plate of 304.......few bucks at a fab shop

-plate cut with torch to rough shape of template......few bucks

-1' piece of 3.5"ss pipe.......few bucks from internet or shop

-hour under car with the flange bolted tight to get the right angle cut into the end of your pipe and to mark them so they line up......free

-getting the pipe and flange TACKED together so you can test the fit......few bucks

-getting it seam-welded when it fits......few bucks

-hacksawing the excess off level when it fits right......free

-couple days work... open dump sound, power, and spool........priceless

ive run mine for 3 years now with no problems... a little loud for my taste but it will easily outspool the full 4" mandrel exhaust i made (and this is only on factory twins)... main reason, though, is for the added ground clearance...

btw... you could do this whole project in a saturday if the even if you had to drive back and forth to the welder/fab guy a couple times... give them a heads up and have the template ready in the morning...
