^ then your screwed LOL any down stream o2 sensors will need to stay there otherwise your truck will run rich and get horable MPG I think you can just traight pipe it and just weld a bung on there for the o2 sensor in close to the same place.

 

There isn't any testing around here thankfully so I might just take em off. But would that make it too loud is what I'm worried about??

 

no, it wont be that loud hell some people say it gets quieter lol.

 

What do you mean by downstream o2 sensors?? U mentioned them once before. I know there are none AFTER the cat but I didn't notice more than 1 on them

 

is there any noise ordanances around where you live? check into that there are a few up here in Maine luckly i can keep it quiet most of the times unless i get mad then my shift point goes from 1,600 to 2k

 

Only in summit county. Which is the next county over. And ironically home of summit racing. Where I drive to once in a great while. Noise wouldn't be my concern I guess because if it's THAT overpowering I could always throw on a muffler

 

down stream = after cat

i have to say my truck is the loudest on campus and i go past the police at the maximum level of loudness? LOL
and they just sit there now if i had a v8 with the same set up i would get pulled over for sure.
some POS Chevy blasted by me one day with i doubt any exhaust and it hurt my ears when it went by almost like a harly with no pipes on ouch

 

Okay so there's none of those. I don't really know what that means though. Would there be a difference in gas mileage if I ran straight pipe as opposed to how it is now?? I think I already asked that LOL I just want to make sure I have the answers straight before I screw anything up

 

If you gut the cat, does that affect the fuel efficiency or horsepower? I have two cats and something else between cats and the muffler. What is that?

 

My truck has the 2 cats but theres nothing between the cat and muffler?? Idk I haven't been under any but mine. And I wouldn't think you would. Gutting em is the same as tearing em out except it looks like they're still there. But I'd wait on one of them to reply. They know more than me :p
