I have received my crawford intake plenum, crawford hi-flo cats and fujitsubo y-pipe. but i'm still waiting for the fujitsubo exhaust. the exhaust should be here next month.
so my question is, if you were me, would you install the cats, plenum and y-pipe first or would you rather wait till the exhaust arrived and install them together at once?
thanks for you opinions..

 

I would do one at a time.....so incase you screw something up and its not running right...u can go back to the last thing u added or changed....and say.."where did i F*** up?" ....so go ahead and start

 

Do the plenum first (I think you may already have). Then have the exhaust side of the mods done by a pro. The bolts on the cats are a PITA to get to w/o the proper tools and the y-pipe is 2/3 of the way off when you install the cats, might as well just go ahead and remove the remaining 2 bolts and swap the y-pipe out at the same time.

 

Have to agree -- Having a pro do exhaust will save you a ton of hassle and it's usually pretty cheap for bolt on parts. When I had mine done, it was a joke how fast he had it all together. That is, unless you have a full hydraulic lift in your garage...
