2 1/4 with flow 40 with cats(DUALS)

This is what I would go with. If you are running the computer, you will need the feedback to work correctly. what is the engine out of?

Not to mention passing inspection depending on where you are.....Anything over 2 1/4 with or without cats is a waste till you break about 400 HP

man redxblaze, we agree about everything

not only is it a waste to do it, its a waste of torque. Sure its cool to say ive got 3" duals, but its gonna kill your torque. You might make 5-10 more horse above 6000 RPM, but I dont think youll ever see that anyway. :thumbup: Flowmasters ARE the way to go though. 40 series rule!!:headbang:

Definitely, only point I'd argue is the flowmasters..Yes they have a distictive sound but as far as numbers go the Ultraflow Dynomax's meet and or beat them in the numbers game..Just my 2 cents......
