does anybody know what size aftermarket exhaust i can put in? I've been told 2.25in is the biggest but i just would like to hear from everyone else.
And the best way to PlastiDip your rims.
i'm on a budget and the car has 220k miles

 

--- Leave it stock bro. Enjoy it while it's still good. Just some good advice. But there's plenty threads on here about that. Good luck bro! Hope it all turns out satisfactorily for you.

 

You could put however large of an exhaust you would want really, but I would think if its N/A you really wont benefit from anything much larger than 2.5''

Also just remove your wheels, clean them thoroughly, then spray them with plastidip after taping off the tire.

That or just try to get some newer OEM lexus wheels like IS300 17s or 3rd gen GS wheels, they will end up looking a lot better than the factory 16s.
