Hi There,

Looking at buying j's Racing header and will purchase a highflow cat with a dual 70mm spoon exhaust.
Am I buying the right exhaust for this header and what realistic gains will i get with this setup in Rear wheel Horsepower?

If anyone can also give me a good price on j's Header wil be much appreciated

Cheers
Russ

 

i think the 70mm is perfect for that setup. as far as gains i would suspect you would see possibly more midrange than higher hp's. as a N/A street car im sure the midrange is what you would benefit from more. need to find some dyno graphs of the header on a s2k then you will be able to tell what kind of gains your looking at. i would do a quick google search or do a search on here to see if you can find any info.


but def a nice header and exhaust setup. you should post some sound clips once you put it all on.

 

Thank you,

Im also ordering Brian Crower stage 2 Cam from the states.

Then putting a carbon fibre Bonnet.

My car sould be ready by febuary as somone dented my car at a carpark so im getting my panel sprayed also.

If anyone can save me money on j's header much appreciated.
