Yes it will fit just fine. The difference in the 2.4s is the downpipe.
Ive ran a zzp shorty and zzp midlength with zero issues. Though the JBP did not fit my 2.4 auto it hit on the coolant crossover pipe. And to my knowledge the 2.4 exhaust manifold is the same as an LSJ one. Even for an auto.
But im currently running the zzp shorty which is intended for use on an LSJ L61 car and it fits perfectly fine.
Honestly unless your worried about your warranty theres much better headers out there than the GMPP one and I do suggest you look into one of the many options.
