I know this is a hard question to get an answer that everybody argues on but who has the best drag porting RDZ, K&T, Herrjuggs, etc....... just wanted to see who has a better reputation as fardrag raceing.
The welds on shearers are good just like cpi's but if your bike is all top end you should which over to shearers cuz those pipes are ment for top end I have a friend that has cpi's n another that has shearers there's not that much of a difference. But there is a difference you can feel and it does matter on porting intake n exhaust
