The Stovebolt Site Forums The Shop Area The HiPo Shop exhaust question

everything I find on the internet states that on dual exhaust you need the primary pipes to be equal lengths. my question what do you do after the headers on a 292? I have the dual long tube headers which I want to use an x pipe and dual mufflers with pipes out the sides. does the equal length apply after the headers?

I believe it's for the V series engines. To help promote scavenging of the exhaust gasses. X pipes = more top end pull if you have the ponies to worry about it. On a stock/mild build I wouldn't waste the money as there will be little to no noticeable benefit. Not trying to burst your bubble.

The equal length is for the header tubes. Good luck with your project.

The X-pipe, while arguably not a performance advantage in this case as Hollow65 states, will help mellow the tone of the exhaust. Consider a H-pipe, should be an easier install and more cost effective.

If you want the classic old school sound neither are needed.

Should sound awesome either way.

great! that is what I needed to know.
thanks

I just run an H about 1 foot past the headers. Crossmember kinda dictates what I can do. Still got the 2 piece driveshaft also and pushin over 700hp and 600ftlbs. The x does sound cool at high rpm though.
