TIM 5O Posted February 9, 2012 Share Posted February 9, 2012 Looking at improving my exhaust on 2.0 VX either a complete system or just collector and box without cat Link to comment Share on other sites More sharing options...

k.russell Posted February 15, 2012 Share Posted February 15, 2012 Tim.you say improving, in what respect. is it a noise thing or looking for more power. what do you have on now, manifold silencer etc. i have a JPE manifold, that is a longer than standard primary 4 into 1 and a part built silencer that i could perhaps finish, but not imediately. here is a pic of the manifold the silencer would be a copy of this, as fitted to my car now get in touch if you would be interested.

Lee Fowler Posted February 15, 2012 Share Posted February 15, 2012 If you are going to change you really should be thinking 4-2-1. Lee Link to comment Share on other sites More sharing options...

keybaud Posted February 15, 2012 Share Posted February 15, 2012 Quoting Lee Fowler: If you are going to change you really should be thinking 4-2-1. Lee What are the benefits of a 4-2-1 Vs a 4-1? Link to comment Share on other sites More sharing options...
Stationary M25 Traveller Posted February 15, 2012 Share Posted February 15, 2012 Better gas flow resulting in a lot more mid-range torque Link to comment Share on other sites More sharing options...
Lee Fowler Posted February 15, 2012 Share Posted February 15, 2012 *arrowup*. 4-1 for peak power and race. Lee Link to comment Share on other sites More sharing options...
TIM 5O Posted February 16, 2012 Author Share Posted February 16, 2012 Sorry for delay in reply to my original post but have been away without web access The current system I have is 4 into 1 but the collector and silencer need replacement for both noise and efficiency the manifold I have has the longer primary like JPE car only running standard with 208 taper TB kit Lee - thanks for info K Russell- thanks for offer Link to comment Share on other sites More sharing options...
andy_h Posted February 16, 2012 Share Posted February 16, 2012 He has a 2.0VX, torque isnt' an issue 😬 K. Russel, Is that a re-packable type? Depending on price I may be interested in second dibs after Tim. Link to comment Share on other sites More sharing options...
