you wouldnt notice the difference because you can count the hp gain on one hand alone. if you have the bullets thier pretty much straight pipe with a resonater. your only restriction would be your cats if you opted for them. why not give me the money so i can be faster

I think it would affect your tune.
I just installed my LG system,no cats b&b route 66,i scanned the car with the stock tune.The car is extremely rich..o2s read .985 across the rpms,(was .910 with stock exhaust and gutted cats .880 to .900 is ideal,thats .985 is hella rich,rich kills power,at the 1/4 mile,my times did not even change.I'm still waiting for my tunner to arrive so i can get the power out of my headers.
Your cutouts would have to be after the o2 sensors,if there is any flow change (minimal i bet),it would affect your tune on the rich side.I wouldn't waste my time with them.Just my opinion.

I do not think it will get any louder with the cutout or you would gain enough power to make it worth it. I just took off my B&B's this weekend and put my stock Z06 mufflers back on to modify some things. The car sounds like it does not even have a cam anymore. The B&B's only have 8 inch long bullet sections which does very little muffling of sound or restriction of flow.
