Brilliant I'll have one of those Vocky, well something made locally as close as possible, maybe it'll give 4 BHP   I've read that the 2.4 intake is the way to go, but I've got a lot of homework to do with the remapping and where the sensors go etc   I can't find any detailed info on the stock NA specs, anyone know where I can find it, I like playing with calculations   Hope to get it on a track next month, can't wait.

Have a look at Mark Verboom Speedster site and you will find details as he made some measurement.

Nice one thanks Vocky, great system you've got there, is that a Cat2 after the U bend.

 

The pre a post sensors are so close to each other did you have any dramas with that

 

first sensor is for idle mixture, second is for AFR gauge, no post cat sensor with Webcon throttle bodies ECU

 

It was the only place I could squeeze a cat, it took two weeks to build the exhaust system to ensure it still fitted inside the OEM heatshield

With exhaust manifold pairing I found there was no straightforward answer to which would be best. Like a lot of tuning it will improve in some areas of the rpm range and loose in others. I know 2bular were developing a very long runner 4-1 (that never got off the ground) so this could also be an option.

Here is the weapon r (tusudo) manifold modified by 2bular to fit the exhaust system:
