7.7 and RD Logics

[Brushlessboy]

Hey guys and girls. I have a Cen 7.7 in my Savage ss, as I'm sure some of you know, and it has an RD Logics 4 outlet pipe on it. During run in everything was going sweet but now I've started tuning it to go, I'm having trouble with it. I know the four pipes aren't good for back pressure but I thought the .46 would be enough for it.
Could I be right in saying I need to change the pipe?
I'm going to block 1, then 2 holes with bluetak to see if it becomes tuneable.
Do you think I'm on the right track or should I be looking for leaks somewhere?

Evening Brushless.....I was thing the same thing and plug up a couple holes in the pipe. I am a fan of old fashion tuned pipes myself.....I would try that and if it does not work.....try swapping it out. If it still being buggersome.....start checking for air leaks and holes in fuel lines.

I saw pics of your truck with that pipe and was wondering how you were able to run it. I was never able to get an OS.30 to run with one of those.

I think you're on the right track by plugging holes, but the overall design of the pipe still leaves me with a question mark. Let us know how it works out.
