4 Blackwing Gigs Throttle Body Install

[DesertRJ]

I have the JB4 and new colder plugs. It was a night/day difference. I want downpipes too. I thought the TB would complement these mods, but not sure how much.

With increased airflow I'd imagine it'd be even more pronounced is my guess.

I haven’t bought DP yet… I want catless, the one with cats throws codes anyway, might as well go all out

Any issues on the stock cats with the jb4?
