Alright, So i been looking around for parts and i noticed the base tl doesn't have alot of parts besides some basic parts. I want the Tanabe Exhaust and the Eibach anti-roll kit and some other parts as well. Would these fit a base model?

 

Not sure if those are considered "Type-s" parts but you can probably find those parts to put on your base model.

 

I'd imagine, for the most part, the -P & TypeS are predominantly the same for parts compatibility.
I could see some specific items relating to TypeS specific engine parts being an issue, but suspension-wise, should all be compatible.

 

AFAIK: CAI, TB and MF spacers are the parts that are not interchangeable between base and S.

 

Tanabe exhaust, & eibach roll kit will work.
I'm looking to get the Tanabe medallion touring cat back exhaust (part # T70078) for mine, so far I got quoted for $1295.
