Nope

Buy the one 100% designed and 100% made in the USA and you'll have 10 more horsepower.

My first Banshee had the original FMF gold pipe, they was a little better than FMF Fatty and T5's before and after porting.

Didn't you win the stock swinger class and the 5000 KOTR money.

I thought the King Of The River races down at Whitefield was a good indicator to how the pipes stack up in the real world!

It's been my experience the shape of the exhaust port dictates the reliability of the engine. OEM cylinders with wide, square exhaust ports will catch the rings, A wide squared off exhaust port on a Cheetah Cub/DM will take out the intake bridge eventually. A cheap Chinese crank with the 29L rods have no reliability at all. It's best to use a builder, they will sell parts that are reliable and known to be good, along with port jobs that will last a lifetime.

They look a lot like the T4's I had, T4's made 68hp on my stock stoke and bore engine.

What was you looking at? LED's come on 700ish rpms earlier. Awesome.

The Redline Servals have been peaking around 9900-10000 with Sniper and Shearer pipes, different porting on this engine?

Runs 11 and 13 LED Runs 6 and 8 Sniper

Why are you making all new stamps when you already have dies and stamps made?

Twister cylinders have a bolt on flange made of thin steel tubing, my flanges are 43 millimeter ID. My 10 mill DM was ported by Mccoy, it made 140 with 43 millimeter ID exhaust flanges. My builder would not waste time putting a big flange on a big Twister cylinder when the head studs block off the triple ports.

Just want to make sure I understand the new pipes, My stock bore stock stroke (350) gets the same pipes as my 7 mill bigbore Twister (568)?

My pipes are for a 4 mill engine. 1-1\16 is one size smaller than my Shearer pipes.

I've had OOF and in-frame Grand River pipes on my bike, both caused my engine to overheat severely. The in-frames came with Pro circuit tailpipes and silencers and the OOF's had 7\8 OD stingers. I had both pipes on the dyno and had been tuned to 13.5. My engine never overheated again after I put Shearers on it. Don't Pro circuit pipes have a 7/8 OD stinger and tailpipe too?????? I don't think he understands that a 4 mill 73 bore engine puts off a lot more heat than a 4 mill 64 bore.
