a 42/48 getting full boost at 4500 on a b16 ??? id think theres something up with your charge pipes. i dont see how this has anything to do with your exhaust. just un hook it and run it open down pipe

it would affect it if there was an exhaust leak before the turbo

Take off the mbc and see if the boost is steady.

it wasn't even before the mbc was on, and took just as long to spool too :-[

alright, i went out and started taking stuff apart. i found a small exhaust leak where the wastegate bolts onto the mani. cleaned it up, and bolted the fucker on as tight as i could, and it's still the same. i'm not using the gasket that came w/ it because everyone says that they just burn off. so i dk what to try next ???
