DG pipes

[slaughter]

so i have been looking to get a new expansion pipe for my tri-z i wanted to know what the differences between the DG pipes are Factory Race pipe,extreme exhaust, and the national exhaust pipe
is there any difference other then price oo yea and the works pro pipe

[tecat-z]

They all have the same dimensions. And actually work well on Tri-z's regardless of preferred finish.

[slaughter]

is that all the different names are is just the different finish

i know the expansion chamber on my DG pipe on my 250r is bigger from the exhaust port to the actual chamber.. other than that didn't notice much differences.. but thats on a honda.. I would hope there are some improvements to the factory design other than being shiny lol
