Hooker LT , Hooker OFP and Mufflex 4"?
Should flow good?
What do I do to get rid of raspyness? Why is this a LS1 problem? Y-pipe?

Thanks!!
I plan on adding a cat to this, so it'll probably eliminate any rasp, and cut down on drone.
Thanks!

How about a 4" cat on my mufflex catback... does anyone make a cat that big?
Has anyone added resonators to their exhaust? Did you dyno? I wonder how much hp loss you get, and if it's worth being quieter on the highway (less drone too I'd imagine)...
Thanks!
