exhaust ideas for turbo foxbody
Currently running a 5.3 with 76mm tubonetics turbo and 4inch down pipe. should I just run a 4 inch exhaust all the way thru, or 4inches about halfway then 3inch to 3 1/2 till the muffler to create some back pressure? Im not using a catalytic converter just straight thru piping. Thanks in advance

just to create back pressure due to not having a catalytic converter. But your right with boost think im going to run a 4inch downpipe and 4 inches all the way thru.

Just run the biggest diameter tube you can fit. Typically though 3.5" all the way back is OK. A 4" system is OK but it will be harder to route between the engine and frame rails.
