U8RSAND-Az Posted April 17, 2004 Report Share Posted April 17, 2004 Hey guys what is the hot set up for big engine in frame drag pipes? I have a 496cc T-Rex with 35mm PWKs, stock 89 frame using late model a-arm conversion and a Clark 5.5 gal gas tank. From what I gather most of the people on the West Coast run CPIs. What else is out there and is there any thing better or worse? Quote Link to comment Share on other sites More sharing options...
Screamin_Banshee Posted April 17, 2004 Report Share Posted April 17, 2004 CPI seems to be the choice of most ppl, when it comes to Inframes. I am sure there are others, I am not sure of... Maybe Shearer? Maybe Rocket? Quote Link to comment Share on other sites More sharing options...

I've never met or talked to Mike, but I've heard for some locals that he knows his shit. Quote Link to comment Share on other sites More sharing options...
350duner Posted April 18, 2004 Report Share Posted April 18, 2004 I'm not sure if CPI makes in-frame big bore pipes. Their standard inframes stick out pretty far as it is! Mike says if your bike is over 450cc the big bores will give you a few extra hp. They can custom make pipes to your motor which is a good way to go. My motor builder has Mike custom build pipes for his fastest bikes. You give them all the specs on the motor and they'll build pipes that will make it run like a raped ape. I have a custom CPI in-frame on my 350r and it helped a lot over the LRD big bore I was running. Quote Link to comment Share on other sites More sharing options...
