Ordered the rest of my exhaust components yesterday, I’ll have everything by the end of the month; got a Blackhorse Racing stainless header, ZZP flexpipe (really nicely made downpipe flange with curved flexpipe), and two mild steel 02 bungs, one of which will be filled with my downstream O2 sensor, and the other one reserved for a wideband O2 sensor for an AFR gauge... all pipe will be 2.25” from the manifold to muffler, which should be adequate for up to ~ 235whp I think? (what the LSJ community says at least)... with the exhaust upgrades paired with my existing intake upgrades the engine *should* make between 160 and 170bhp
