Exhaust question?

Shamrock

Cool. Where in the first pic is the x and the h pipe? How can a CBE be dual or single? Don't only the TP's determine that. Is the stock dual? This is the Remus CBE

No thats the akrapovice cat back. so basically all test pipes are is about a 1 foot length of pipe that connect the headers to the cat back. they take the place of the stock cat. after that is the "Y pipe" which is shapped just like the name implies. now some exhaust systems connect to the stock y pipe and some replace it. in the case of that akrapovic, it replaces it. whereas the topspeed catback pictured bellow it bolts onto the factory y pipe.

in the picture of the akro system u can see the "H" pipe connecting the 2 sides of the exhaust between the flex pipes and the resonater. this evens out the exhaust pressures in both sides of the exhaust.

here is an "H" pipe and an "X" pipe beside each other:




as the name implies, one is shape like an "H" and one is shaped like an "X". there is really no advantage to one over the other. they are just different ways to do the same job.
basically if you get test pipes, any system that is a "true dual" will bolt up to it.
