ive decided to purchase the slp loud mouth 1 system tomorrow and i was looking into as well replacing the factory y pipe with the slp y pipe i was just wondering if it would make alot of difference in sound and power for the money or if i should keep the factory y ... thanks for your help in advance

 

The factory y-pipe is flat and has some flow restrictions, the slp y-pipe is a little more "free" flowing so it is worth the money and will bolt up to the factory cats easy.

 

love the rims joe
