Question regarding what parts from Gen1 will fit Gen2
 

I did some research and found out the following will not fit from Gen 1:

1. EL headers will not fit, some UEL headers such as Tomei will fit.
2. OEM styled exhausts will not fit, can styled ones might.
3. Strut bars will not, ones with brake cylinder brace definitely wont.

Does anyone know if the following will fit:

1. Cusco engine room power brace
2. Cusco underbody braces
3. Any rear frame bar
4. HKS hi power exhaust
5. Sway bars?

the overall chassis didn't change much if at all, so while i don't believe anyone's specifically confirmed any of the body-specific stuff, i believe just about anything south of the engine ought to fit.

but the strut bar above the motor might not clear due to the motor revision. i know the front strut towers changed some.

OEM style exhausts fit just fine, as long as they’re catbacks, not axlebacks.

The only catback exhaust I’ve heard of so far that doesn’t fit is Xforce, because their midpipe to muffler flange sticks out way to the left hand side of the car and digs into the rear bumper aero skirt

Header outlet flange / Overpipe inlet flange is clocked different than Gen1. Some Gen1 parts will "work" with some rotation of the parts. This rotation could cause interference on others.

Rear diffuser sits in much deeper than gen1 so any muffler or tip that exits at an angle risk some interference with the inside of the bumper/diffuser.
