Anybody have experience with manual transmission 6.4, I want to install a down pipe with my new 59 72 turbos. Wanted to get opinions on what brands might fit the best, I know some grinding might be necessary, but wanted to keep it at a minimum. Already tried a afe 2 piece it bolted up but hit the firewall pretty bad and was pinched between the bellhop sing and frame. So ordered a sdp hopefully it will be closer.

I have high powers on mine and every downpipe I tried was a disaster. But since yours is still a factory style turbo you should have better luck. If I were you I would cancel the sdp one cause mine went right into the bell housing. But it fit the best by the firewall. I found out in the past that a flo pro fit the best. I had one on my stock turbos and cleared perfectly. Right now my downpipe is mangled down to 3" in some spots. I had to beat the living crap out of it. I saved my sdp one cause I'm gonna modify it to fit around the bell housing when I get time.

I have an sdp one that I never got around to but was told would be the best option for zf6 trucks. Went to a single from midwest now so I am gonna have to modify everything.

I had a diamond eye one on my stock setup. That fit pretty good once I dented it for the bellhousing. The sdp I would say is the best fitting one out there. There was a rumor not long ago that RCD was making one for the 6 speed crowd. Maybe give them a shout and see.
Lol well I would have modified the afe but it went right into the fire wall and everywhere else. So if the sdp clears the firewall I'll be fine modifing down low.. Thanks for all the input. Another question how do you guys like driving a 6 speed with all the power compared to a auto. Obviously they shift like tractors lol
