Exhaust set up for 450 hp

ciara · 06-03-2002, 04:40 PM

I currently have open headers on my car. It is a 351 windsor. It has about 450 flywheel hp. What kind of setup should I use. It is drag only. I have heard of X pipe, H pipe. What diameter pipe should I run? What is a good set up and will it help my hp?

Drag car only....open long tube headers will give you best results. No X or H pipes....

That's not true, that's old school thinking. It's been proven over and over, an X-pipe will make more hp/tq than open headers on moderate hp drag cars. I'm not talking top fuel race cars, rails, or 1000 hp beasts. With 450 flywheel hp, an X-pipe and 3 inch exhaust will suit you best IMO.
