this is a used twinscroll pipe kit i used on my girls car. its made from 1.25 sch10 stainless steel. flanges are all 1/2 thick stainless steel. the gate flanges are for 44mm tile gates (gates are not for sale). the up pipe uses a standard header gasket and the other is a divided t4. this kit will fit most t4 flanged turbos. the down pipe is 3.5 16ga stainless that reduces down to 3inch at the flange. it has the borg doughnut style flange on it now that i can swap out to fit what ever turbo you want if you don't want the s366. the side dumps exit the bumper and i have a stainless steel plate i made that bolts threw the bumper to keep it from melting or burning. you don't have to go threw the bumper, you could point them down as well to have them dump just under the lip. i also can throw in the intercooler pipes to that are in the engine bay. it should get you close to any intercooler you would have. they need a new paint job but other then that the should work well. the tb side has a maf flange on it and a tial 50mm flange. any questions feel free to ask. asking 1800$ also have a borg s366 for sale. turbo is in good working order and would keep it if it would work on our new compound set up but i need something real big with a huge ar housing. this has a divided .95 housing on it. its a 66mm inducer. any questions feel free to ask. oh and the bow comes off and compressor will be shave and cleaned to look good when sold. asking 600$
