Re: h pipe or x pipe

How do you pass emissions with true duals, and what about the o2 sensor after the cat?

its easy you have one high flow cat befor the o2 sensor that sensor is only reading one side of the engine so you will pass, I do nad my cats is no longer than my hand and you can see the sun right through the inside.

Re: h pipe or x pipe

the x-pipe is known to produce more torque, and the H-pipe more horsepower gains.

they both equalize exhaust pressures = less snap, crackle, and pop as compared to true duals.

you have your information mixed up
