Factory b pipe 650 vs 701

[surferdude345]

what is the major difference between the 650 and 701 pipe?

 

[Matt_E]

I believe the 650 Chamber is smaller.

I posted this on the other "ban friendly" forum before...

Pictured here is my limited SJ chamber (top) and the 650 SJ chamber (bottom).

The other diff is the 2-1 manifold has slightly smaller ports...but can easily be opened up to work on 701 (61x or 62T).

Has anybody run that 650 chamber on a 701 before? If so, how was it?

I'm running a coffman 650 pipe on my 61x. I had to port the exhaust manifold to match up with the 701 ports and it hits! I would never consider spending 500 bucks on a B-pipe when this one works just about the same imo

I thought I remember reading the 650 chamber works well for a stroker.

I would think that the size of the 650 chamber is about the same size as a mod. So it prolly would work well for a stroker Robert. Just a guess though...

Looks like it will fit better compared too comparing both chambers side by side(no banging the chamber in, etc..)!!!!!
