i may be mixing up my asp's but i'm sure i remember reading it was a copy of the one mike kojima got burns to make for him?

Would be great if Jamie tested that header and a 4-1 on that motor.

Doctor G can you share those tri-y specs please? also which touring car were they for?

and there is more to jamie's numbers than just the header

Yep the deluxe Snickers 4-1 is the Burns copy, the 4-2-1 budget is not a copy but a Snickers original initially made to fit a P10 but with a bit of crossmember massage does fit the B13/B14.

No. Same header/person. Snickers is his screen name, ASP (Advance Street Performance is/was the business name of his company.

ASP budget header 4-2-1

ASP tripple stepped header 4-2-1

ASP 4-1 header

He makes difference variations, it just depends on your setup/goals.

P.S. Snickers/Charles has not been with ASP for 2-1/2 years now.

thanks a lot

The gains from bigtube are clear but what would happen in a stock bore engine?

I'm about to replace my cheap ebay header for a tri y soon
