I have a CPT66 I purchased from Cotton's this summer, less than 100 miles on it. It is a Turbonetics, polished housing, set up for for an ATR with an external gate. 3 inch in 2 out. I'm considering going even bigger. It is still on the car and I've been considering selling it. I could let it go for 800.00 plus shipping. Would have liked to do a partial trade for T67Q trim or PT70. Phil
