What stuff from the acura legend is compatible on the the 1st gen 3.2 TLs?

Ive heard some intakes are, but what about exhaust, etc?

 

Ya the intake is. If the exhaust isn't just get a universal one.

 

No im talking about headers, and other things like Y pipes....

 

Most likely not. Engines are similar, but those kind of parts are made specific for the cars.

 

Its possible since they are the same engine and chassis. But... the big question is.. did emissions rules affect the HIE (headers, intake, exhaust) at all. It is quite possible that certain changes were made. (To improve emissions, new equipment etc)
