CPI and Shearer for sure.

i wouldn’t pass on Pro Circuits either as they are great pipe

[Schweet97Z]

Put on smaller carbs and run PT Mids or SLP’s

Shearers are the best pipes money can buy

[B-shop164]

Shearer are the best ? Not to big for that setup?

[Ayesully810]

If your cylinders arent ported out too much you will like em.  they hit really hard and rev good.  if they are ported out a lot the bottom end will suck just know that.  if so, that mixed with 35mm carbs and shearers it will likely be a turd on the low end

so the shearers are the best and they are better than the t5 on a setup like this

[Toybreaker]

Shearer and CPI are top end,

dirt and flat track are all pretty much top end racing

 

So Yes Shearer and CPI pipes are TOP END pipes so they would be better than T-5's for what you plan on doing with your bike.

What kind of dirt flat track racing are you doing.

 

Everyone here is assuming your running oval.... which in that case they would be right

If your racing in tighter tracks with hard turns and hairpins... your going to find yourself fighting the motor if its too top end oriented.

^ that. How big of a track? 1/2 mile ovals, go Shearers or CPI. The CPI will have a tad bit more grunt if you need it to come out of the turn harder. If you're running real short tracks or twisty TT stuff, try a set of SLP's or PT's. T5's are a little lazy for my taste.

I use for long oval  track and for ice racing oval , i will change my pipe for a cpi or a shearer 🤭

[ZillaFreak]

Why do people continue to compare drag pipes (shearer, CPI, etc) to a garbage pipe (T5)? They are not same pipe and not designed close to the same thing.

Can you run of pipes for that kind of racing . Top end benefits with better torque
