Guest Usmann A Posted June 12, 2004 Share Posted June 12, 2004 Hi Dave, From what I understand/read, there arent may pros and cons regarding this topic. I think the main factor is the noise appeal, as long as the gate is allowed to dump excess pressure freely, than I think, the rest is choice. If you want sound go for dump tube, Link to comment Share on other sites More sharing options...
dude Posted June 12, 2004 Share Posted June 12, 2004 Normal thinking is that slightly more powre is available with an atmospheric dump , dont ask me why just what i was told Dude:flame Dev Link to comment Share on other sites More sharing options...
Ian C Posted June 13, 2004 Share Posted June 13, 2004 Blending the wastegate gas flow back into the main exhaust pipe causes turbulence (varying on how smooth the blend is), which increases backpressure. That's about it really. -Ian Link to comment Share on other sites More sharing options...

Wez Posted June 13, 2004 Share Posted June 13, 2004 Not really, I also had a small silencer fitted to my dump tube as some tracks you will fail the noise regs. Link to comment Share on other sites More sharing options...
