header pipe ?

[hippy440]

I know somebody just asked almost the same question but here goes I have a 440 with 11:1 piston and a small cam i have a white bros r4 silencer, now i want to upgrade the header, does anybody make one that will fit my silencer that's on my stock header? does a bigger header make a difference on a 440? I called white bros. they said they only sell the header in the complete system.:confused:

It would be more beneficial for you to Ebay your R4, and then buy a complete race system. Such as the Curtis Sparks X-6 or the White Brothers Pro Meg system. You won't gain much with your current setup and a header because the midpipe will still be the stock size.

Put you a powerbong on that sucka....:devil
