i have a few questions:
1. i have a 4.7 do i still need 3.0 pipe size...i believe i do?
2. Do these kits have to be welded on or can they just be clamped on?
3. Will this truly make my truck louder, i have the gibson supertruck and am wondering if it is worth doing?
THANKS for your help!

 

can be welded or clamped. I love mine and it is 3" also

 

Doesn't a cutout screw up idling and stuff like that because there is no back pressure? I want to get one too, but I don't want to go cheap on something like that. Is there a specific company that is known for cutouts, or that anybody has had good experiences with?

 

no it doesnt screw up idle. dmh is a damn good cutout, once i smog mine next month im getting one....damn CA
