Does anyone know for sure if the exhaust from the cat to the Y (just before the mufflers) is the same on the TL vs the TL Type S? I'm interested to know if the tubing, resonator, and mid-muffler is the same between the two cars.

 

from my knowledge, its just the tips.

 

I can tell you for sure that the resonator is the same between the base and type s

 

i think its only the tips that are different

 

Tips-y.

 

Just the tips...

 

C'mon baby, just the tip.

 

The rear mufflers are the same too? I always thought stock TLS mufflers were louder than base.

 

Just the tip baby, please.

here... type s muffler. i know theres one with a base muffler too but im not gonna do everything for you

 

Thanks guys!

 

Looks like not only the mufflers but the cats are also different on the type-s compared to the base. They have a lower cell count which increases the air flow.

 

^correct, on the primary cats. the two near the heads.

Base TL has a cell count of 900
Type-s has a cell count of 600

But the OP was talking more about the factory "catback"
the tubing after the Jpipe.
