Was fitment alright on your GS430 or did you have to mod them a little?

the OBX are copies of the S & S (Jbrady helped get made), which then were bought by PPE to fix the fitment issues and cracking issues. the obx are replicas and junk

Don't just say they fit differently and throw out some imoji's. Go into detail if you will about whats actually different between the gs400 and gs430 fitment. Because I'm at a loss. Are the exhaust ports further apart, the cylinder heads angled differently, the transmission bell housing wider? Not to be hostile but...

Hey, you're right. Here is some info..
I believe the Runners/O2 bung holes are different. the runners are of the same configuration for an LS/SC vehicle ( steering knuckle clearance, O2 bung hole positions)
but for a GS 400/430 if you look on the FIGS Website, you will notice that the selections for the header options are separated by year and make.
I know for a fact that the LS400 headers will not fit on the GS400. it sounds crazy but the headers for both cars are built differently even though they share the same engine. I learned the hard way.
if you are looking for a set perhaps it is best to contact PPE for further information. Make sure you do your research before you buy on here.
and PLEASE, DO NOT buy OBX brand headers. you will regret it later.
