In reference to these dumps .they appear to rejoin after only only a few inches .

what a lot of people dont understand about the design concept behind the dumps is removal of heat
Its excessive heat that kills factory turbos . to get the huge torque gains from twim pipes they need to be BIG

so you need twin 2.5 inch dumps and i would run them at least half way down the car before re-joining .

ALL the flow probs come from having excessivly large pipe after that .rejoin then 3 inch and you can still run 10 psi boost .

i do and easily still make 300 rwhp at 15 psi with an auto .so around 320 with a manual
