How long have you let it idle for? Have you driven it at all? FYI - the computer needs some time to relearn with the new exhaust, especially O/R mid-pipe. good luck

You NEED to install the front O2 sensors. Your computer uses those to manage your a/f and timing.

You can do away with the rears (pretty much have to with O/R) but the fronts play a crucial role in your entire engine management system.

i fix the idling problem i cut the wires for the o2s and made them longer and the idling is good.the exhasut is loud but just found out why the guys at the shop forgot to weld the middle pipe for the h pipe.the one that connects both of them together.at least the summit o/r h pipe is like that.does anyone have similar exhaust and had any trouble??what i mean this exhaust is still loud and want to know if u guys had trouble with the law??

I Havent gotten any warnings or and trouble from cops with my setup with single chambers.Car is loud as hell to and all ive gotten is compliments from cops.If the car is driven daily though you WILLLLLLLLLLL get tired of how loud it is!You can hear my cams so much better with this setup now to.

O/R H w/ 1 chambers = after a while.

There are days I wish my exhaust was more quiet. And then I wake up the next day and wish it was louder. I think I may buy a Mac H section so I can swap between prochamber and H pipe whenever I feel like it.

hey were thinking about putting 2 of the stock cats back in it will that help???we need to get it a lttle less quieter.

I've got O/R X with 2 chambers for over a year, sounds just loud enough

You will have to add a little bit if pipe if just switching mufflers because the 1 chamber muffler is half the size of the 2 chamber one.Unless you just switch the whole catback

well, we traded mufflers. i installed the 1 chambers in my car but installed my tailpipes back on.(i had turndowns). he has my 2 chamber flos and the car sounds pretty good now. i like how hes sounds better. my sounds nice but i thought it was going to be louder.its still good
