It's a bit backwards :P but I got a killer deal on brand new LTH's and the y pipe is more than half the price as the CBE's. It probably won't be installed until Feb unfortunately because I'll still be out of the country till then. It will be like christmas... funded by me and for me.

And please don't take anything to heart because we both know our answers are hypothetical until proven. I also completely agree that LTH's are not worth it for most people and "similar" gains can be achieved going a different route. IMHO, nothing beats the sound of a nice car that has a full exhaust setup with long tube headers. That scavenging sound, the crackles, and burbles to my ears are priceless.
