Doug Thorley THY-323Y-C Fitment

[NC_John]

I have my doug thorley THY-323Y-C's temporarily hung on my 6.7 stroker.

I'm using the CPP sheetmetal mounts and dirty dingo sliders.

They fit really good and look fantastic. Build quality is great, 16 ga with nice thick flanges. Ceramic coating looks really good.

I can fit my entire hand between the engine mount and the header pipe on both sides and frame clearance is just as good. The only issue on mine is the passenger side is hitting the firewall but that could easily be fixed by just inching the engine forward a tad (I have it really set back). We ran these on the dyno and there were no issues with plug wires although I think a stock set won't fit.

I ordered a set of Speed Engineering long tubes and hope they fit as well. I am sure they won't look as good...
