I recently purchased a pair of CFR slip ons, big sucker air cleaner and Dobeck Gen 3 electronic fuel infection module. The dobeck is already preprogrammed for Stage 1 and very easy to install. The new air cleaner was a snap to install as well and finally the easiest thing to install was the CFR slip ons.

The look and sound of the pipes is amazing if you like a low rumble and then listen to them roar when you you get on the gas. Everything I was hoping for and then some.... I have noticed my MPG going up since installing the above items and the Dobeck tuner is very easy to adjust if necessary, very much like adjusting a carburetor by hitting a few buttons on the module. No hooking up to a computer and remapping, etc. Very happy with results.

 

Do you have the CFR's on a stock exhaust with the cat in place?

 

Yes, still stock exhaust with cat in place.
