Hey guys, don't want to annoy anyone with a repeated question here so I did some searching first. I got my magnaflow put on last week and I'm looking into some pacesetter long tubes. I think I want to take out the cats and get an ory. I was just wondering what exactly I have to buy besides the headers and y pipe. 02 simulators? And can a shop install them fine? I just wanna do setup all in one shot to save some money.

Thanks.

 

Yeah, o2 sims if you dont have a tuning option. Maybe some new GM MLS gaskets. Band clamps. Youll have better luck in the external engine section.
