I just was wondering if these systems are that much better than stock. Don't really want to spend the money for the DMC or Big Gun systems.

I used to have the FMF Powercore 4 but changed to the IDS2 with 18 discs. It really pulled better from low to mid to top. I run a 155 main with K&N and 6 1 inch holes in the airbox lid (I live in the Philippines where it's warm around 90f) and Web Cam 450/451 grind. The IDS2 has good power,quality, sound and price.

 

I RUN THE IDS-2 SUPER TRAPP PIPE JUST THE END PEICE, WITH 8 DISC, IT LOOKS GOOD, SOUNDS GOOD,
AND RUNS GOOD. PAID $194. THE MORE DISC YOU USE
THE MORE TOP END YOU GET, AND TAKES AWAY FROM
THE BOTTOM END.
