I got my new Sprint 77 Dom pipe today and all I can say is WOW. I had a xcan with 6" stingers on before and Sprint 77's pipe is night and day difference. I will get some video with my speed gun, but with the xcan I was hitting 36 MPH with stock gearing and a Zenoah 26 with a 28.5 big bore kit. Im going to guess I am now hitting 40-42 MPH now with the new pipe. BTW I am running a MT with the big tires so 40-42 I feel is pretty damn fast for its size and weight. I also notice a big difference is accleration compared to the xcan. If anyone is on the fence about buying a pipe from Sprint 77, BUY IT !!!!!!


Thanks for the great pipe Sprint 77 and hope to do business again.

man, those pipes really rock ha.. i have a 28.5 on a cy bottom end with an X-can and it does no justice.. try to get some speed runs with that thing. love watchin speed runs
 
Seems to move pretty good.... go get a speed gun to clock it to see how fast it goes. I picked mine up used from someone off Craigslist for like 40 bucks.
 
I got mine today as well. It's one heck of a pipe with a very smart layout. This pipe is just as good if not better in terms of quality compared to other pipes. I highly recommend this pipe.
 
I have one on my all alum mt also, AWESOME pipe.


fits inside the chassis / under the body also, very nice pipe.


look at moo's video's for the performance... :eek:


and sprint's workmanship is very good.
 
fellows thanks. Suggestion though for now is to run a nylock nut on the bottom bracket and run it a little loose. the Redcat is flexing so much that my pipe is acting like a chassis brace and the bracket is taking all the punishment. I am trying to come up with couple different rear brace ideas, if anyone has a Idea they like to show me that is cool too. I have a few good ones but trying to keep it simple so is affordable to everyone.
 
Hey Sprint, I found out the hard way as my mount tab snapped off. Is it really an issue to run without it? Even running with it loose is gonna create some stress on the pipe so I am currently running without the 3rd mouunting point (the tab). I don't think it will cause any issue soon and am going to have a buddy weld it back on. Did you get anywhere with your rear brace design? PM me if you have any for sale.
 
the easiest I'd think would be a 5mm plate of 7075 that bolts underneath and runs back to engine side of the fuel tank the width of the rear diff mounting area.


side note:I kept having the exhaust bolts work loose so drilled small holes in the heads and tie wired the buggers on...they don't seem to move now (a tip from slawhammer from LSF)

How about rebending the flange so you can put a rubber gromet between the pipe and the brace. The rubber gromet should act like a shock to take some stress off the exhaust mounting flange.
 
My tab broke also so I cut down a 2" pipe coupler and used a 3" band clamp to secure it thru the rear support brace on the truck. Added a few small pieces of rubber under it and it seems to be "ok" for now. The rubber clamp and rubber spacers allow a little "give" but the pipe is solid now! Well, at least that's how us "HACKS" do it! I kinda copied it from the Samba mount on FGSupply's site.

That would help. I might raise the braket up without jig changes to try that.


The real problem is the rear flex in the first place that is causing it.


I realy like Slammer design, He said was to hard for him to make them in Production. I may PM him again and see if he might like to contract the Job out, or work with him somehow.


I have one other way I like but waiting on machine shop to get back with quote on the DWG . It intails both tube fab work and CNC machining.
