Good article about X-Pipe & H-Pipe exhausts

Postby brian on Mon Jan 05, 2009 11:01 am

My new car has an X-pipe exhaust configuration. I was wondering what the differences were between X and H pipe setups. This explains it pretty well.

Although they are not Pontiac G8 cars. Gives you good info on their characteristics.

My opinion, you get more flow out of the X pipe(depending on diameter of the joint).
H Pipes would cause a slight restriction due to the 90 degree bend for both sides of the pipe being connected. This probably helps in noise reduction or baffling.

I fear no man nor women, only God Almighty! Proverbs 1:7(KJV): "The fear of the LORD is the beginning of knowledge: but fools despise wisdom and instruction."
