Exhaust on, just another boost leak to sort

20vcqdriver · 15-07-09, 11:45 AM

Well had the exhaust done yesterday and it sounds much better on full bore (if I could hear it over the boost leak..yes its that bad), but still quiet when cruising. Much deeper note now.
Had a long chat wth Pipewerx's Ian Birch who said 3" unnecessay and boomy unless running over 400bhp. 2.5" is good to 300bhp and with a 3" downpipe to my now 2.5" exhaust I can get to 360bhp before backpressure becomes an issue with the freeflow boxes i have. So job done... Also managed to reduce the bend at the rear to help gas flow.
Now to locate this flaming boost leak.... always something to sort on this heap...

nice bit of kit from Pipeworx there. Ian Birch certainly is a bit of a Jedi Master and he's located in a great part of the country too. Well worth a day out for an exhaust and a pub lunch to pass the time
