i was at ace hardware today with a friend, and picked up a 1.5" pvc pipe end. i took of the resonator and stuck it on to imitate the stage 2 GFI minus stage 1 pipe and filter. Didn't notice anything different except maybe more of that whistling haha. oh well no harm done cost 99cents lol. wouldn't use it for permanent solution, it fits snug but never know. well back to stock. i guess im gonna spend the money on something else.

 

get spectre parts for the GF, cost me less than 50.00 shipped from amazon.com if you need part numbers, let me know
