It might run rich/lean but not bad enough to hirt if only for a little while.

Why do you want to gut them??

bc they seem to fail anyway so might as well just remove before that happens. also, free alil more flow and power.
Since mine are new and we smog test out here that is not an option for me. I will say if they fail again before I sell her I will take her to an exhaust shop and have them weld in flanges and add aftermarket high flows with a "test" pipe option.

i dont have a v but reg 4.6 and mine are gutted and no ses light since i use the spark plug non fouler trick. and it does make it look blow by when i down shift all the way down to 1st but thats just the unburnt gas. x pipe no res to two moroso sprial flo mufflers is what im runnung as far as exhaust, its loud but not to look at me while idling or cruising. sounds like a pisse off cobra

Gutted mine two years ago...WAAAY too much $$ for new GM Replacements, and easier than trying to cut and weld in aftermarket cats, due to them manifold placement. Added Magnaflow tru-flow x-pipe, and two Magnaflow mufflers. Ran rich for a couple weeks, then added a FULL Spectre Intake...seems good, and its been like that for 2 years! NO ISSUES!

mine is done, just postd the new dyno vids. if I could figure out how to get the sheets from my phone to upload on here I would. have both before and after the dsteck tune. oddly enough, EXACT same numbers, but SO MUCH better looking graph.
