650 protec pipe on 701

[RiverWF]

I have this 650 square nose with a pro tec pipe on it. Is this specifically for the 650 or would It also work on a 701?

What 701? 61x or 62T? You may have issues with bolt hole size on a 62T and may need to open/port match the manifold to the cylinder on either 701 application.

I run one on a ported 64X 760. I love this pipe. Just make sure all of the mounting hardware/ rubber grommets are in good condition. I just replaced all my mounting bolts and grommets this winter. These pipes can come loose and cause issues if not monitored and inspected regularly. Good, solid and new hardware eliminates most concerns.

Also, some of the pipes I have seen have one mounting tab to the head and some have two. However, the manifold and pipe appear to be the same. They make really good power and sound really good as well.

Hey did you have to port your exhaust manifold when switching to the 701? Or just run it as is? Thanks!

I stumbled on this and have same exact situation. Pro tec 650 exhaust tryng to swap it to the 701 62t. Did you ever succeed in this if so any issues with fitment?

I ended up just getting the protec 62t manifold so I could try running the bigger bolts that go with the 62t cylinders and figured everything would just be an easier install... But wow, was not the case. The 62t manifold route was still a pain in the ***. The holes just did not want to line up. I ended up having to do a combo of the larger bolts and then a few of the smaller ones from the 650 cylinder manifold with helicoils. Depending on the 650 chamber you also might need to drill out a hole in the new manifold.

If I did it again, I'd just try and port match the 650 manifold and use helicoils.

But to answer the question of how it runs without port matching, I do not know. Just figured I'd share my troubles with getting the 62t manifold.

Thank you for the response. I have same exact dilemma. But sounds like its a bit of a job. I was hoping bolt on.wouldnt you have been able to just use the pro tech “muffler” pipe and clamp that to the 701 factory head pipe
