416EX Pipe??

[ride red]

I have a 416 kit in my 400EX with just a Yoshimura slip on, on it right now and have been drag racin it. I was wandering if I put a full system on it like a X-6 Sparks if I would notice a big difference or if I'm just waisten my money...thanks

i think it might help some but it would help a lot if you added a cam and ported the head.

Don't change the pipe until you do some more engine work. Cam and porting most of all.

yes you will notice a difference, but you will ntoice more with a good port job.

get the pipe, a fcr39 carb, port the head and slap in a cam, then you'll see a MAJOR difference
