After testing of the 3 pipes made by Power Pros (Trinity,CT,ATVRacing/Hetrick),,
I like the Trinity.
The CT gave a cpl hundred more rpm's, but is very hard to tune to if you have race porting.
The ATV Racing/Hetrick (same pipe) runs fine, but testing proved the Trinity to give better low end. Top end was the same.
I've been fighting to get 1-2 tenths of a second (in my testing spot, it's like 75 ft.) for years, the Trinity was 3 tenths faster out of the hole. I was impressed.
