slip on or full system

[pauls400ex]

basically right now, i have a stock 05, and i was going to mod it a little, im thinkin about pipe, kn, jet, and airlid and thats basically it so i got the money to get a slip on or full exhaust, im just wondering if it would be worth it to buy the full system?

if you ever plan on doing any motor work such as cam, port and polish, 416,426,440 etc... go ahead and get the full you wont notice much power over a slip-on now but when you get some more motor mods that full system will really shine

sparks, hmf, yoshi, Lrd have about the best you can get
