y pipe = good mod? what's your opinion...
 

Hi guys,

I did some search on the y pipe mod and now I would like to know your opinion about it??? People who has installed it on their Z, did you notice a difference in performance or you would say that I should spend my money on an other mod???

Will I see a gain from installing an HR y pipe on a DE 05z? Will this gain be similar to an aftermarket y pipe like JIC, AAM or tanabe???

thanks
