Regarding Trifecta tunes I guess time will tell.
I personally went with CIA's catted DP wi cutout;unfortunately it's still in the trunk awaiting a tune,etc.-I hope I don't have to leave the cutout open to save my cat,lol.

GM stage tune is 12.8-13.0 A/F not really rich enough to clog a cat but if you hit COT protection it will run a 11.2 A/F.

Thanks 4 the info.I'm planning to keep stock catback-should flow well and sound good w/o drawing too much (unwanted) attention.Plus I can use that money elsewhere
