Any one know of any issues or performance problems with a 99 OEM cat back exhaust being placed on a 2003 TL-S?

 

For comparison purposes this is a pic of the TL-S exhaust. I think the TL-S exhaust is more free flowing then the 99 exhaust.

Pic:

 

The purpose is to go to a free flowing exhaust not go away from one

 

idk. that looks exactly like my '99's exhaust. maybe they have different diameter piping but watever the deal is if you feel your exhaust is cloggy in any way get rid of the cat (unless your state doesnt allow you) or get a new cat//higher flow/hollowed out. I have reason to believe mine is

 

sry to hijack the thread but which one in that pic is the cat?

 

None of those cans pictured are the cat. The two on the long pipes are the resonators. The cat goes right before those two.

 

alright good, couse i removed the big one thinkiong it was the resonator lol and i was hopeong i didnt remove the cat. yes i am a noob sometimes haha

 

Thank you for the response, however i need a definate answer so i know to trade my exhaust or not for a 99 OEM System...

 

the 99 or TLP exhausts do not match up with the TLS catalytic converter. This is why I couldn't get the Comptech catback to fit on my TLP.

if you do get it to fit, i wouldnt expect many problems. i know there were some members who were running superchargers with their stock catback with no problems. to that effect, the power made from a TLS should flow fine through a stock catback, TLP or TLS

 

I donno but I have a 99 TL with an Apexi WS2 supposedly for the 02-03 TL-S bolted up to my 99 with no problem.

 

I would not put a TL-P exhaust on a TL-S. The TL-S has has a 30% more free flowing exhaust over the TL-P

As far as fitment, something would need to be done to make it fit.
