Over time I have tested most every exhaust system on most every size engine. I have yet to be impressed, either on the dyno or on the street.

I have seen a 3K exhaust system cost an engine 20HP, or a set of cheap headers add 2HP to another. I have yet to see the gains that make the drone at cruise speeds or the cost worth it.

This year ALL of my updated engines were fitted with OE mufflers, I carried out the development for my engine program and apply what works.

If you like sound, go for it. If you want less weight, go for it.. If you want HP, reconsider.
