so i want to change the muffler on my 03 tl with something more interesting. the stock ones are totally silent. the canadian tire near my house has sales on flowmaster universal series for 120$ plus labour. reviews for these mufflers generally say that it makes a deep non-ricer sound. i just wanted to know for this car i can just replace the muffler without having to touch anything else right? no ecu mod or anything? so it will just be that 120 plus labour and nothing else? thanks.

 

nothing else needs to be done.

 

well you would need 2 mufflers so 240 plus

 

...and those will be welded on, not bolted on.

 

thanks for the replies totally forgot there are 2 mufflers. i decided to keep the 240 and spend it on hid fogs and tints. im doing them now actually hopefully will finish soon and ill post up pics. not sure if i should do 3000k or 6000k

 

3000k are yellowish good contrast to the stock looks good.
If you go with 6k sometimes having a whiter/bluer light on your fogs than your headlight makes it look off.

 

Just do a mid-muffler delete if you want it to sound better.

 

yeah...until you install headers. Now it's raspy/crappy around 2.5k RPMS
