I am currently running an aussie DP and Mongoose 2.5" exhaust, and i am really tired of the intense drone. I. Have a perfectly fine stock exhaust lyiing around, and with minor mods it can bolt strait up to the aussie dp. With the standalone ecu, the car is now putting out 250hp at the wheels at 15psi boost. Can i expect noticable power loss with the stock exhaust?

driving you might not notice it. it will be about a 7-10 HP loss
