I am debating whether to get the Tsudo Axleback exhaust system for my TL type S or just going to an exhaust shop and getting mufflers welded on. Which one should I go for?

 

just go to an exhaust shop.

 

exhaust shop

 

Any ideas on which muffler I should go for? Or just what brand sounds best on the TL (I know it's personal opinion on what sounds the best)

 

ALL mufflers work the same/built the same; a chamber with baffles.

you wont know how it sounds until you put it on the car.......as you said, it's personal and subjective.
i feel if you put any kind of after market muffler on, you'll enjoy it...
dont over think this

 

How about a rear muffler delete?
