Had a play with the front y pipe 2 day on the v6 gen8. There is 4 cats 2 on each side. With o2 sensors on both sides of the front set of cats. This ezhaust will probly only be in place for a few months...
So i unbolted the ypipe and removed the 2 rear cats. Straped on my m3 breathing mask n in got a large drill i use to hang pipe farm gates with est 20mm by 400mm long. Drilled at the internals of the cats n shock it all out.. easy as that.
Bolted back up no codes. N iv thrashed it..
Sounds good under boot. But where it goes 2in1 its restricted compaird to the size of the factory pipe. .. i think the pipe was est 56mm id. Or round 61. 62mm od whicht i recon isnt bad size for factory.
Yea so the 2in1 restricts alot and the rear muffler deffnatly is doing its factory job. It may be a bit loud if i replace the factory muffler with a free flow i dont know. I down want it 2 be loud on cruze mode, but i want it 2 flow.
Going to have 2 build from the conection back from the ypipe in 2.5" with a slielt free flow muffler im thinking. Gessing that bolwar type.
