What kind of performance cat is made for an 03 TL-S..i know there is one for the 3rd gen but didnt know if they made one for 2nd...

 

Try Random Technology. They make one for 2nd Gen.

 

what gains does the high flow car provide?

 

A high flow Cat won't help out much at all unless you have FI. It may give you a small gain up in the higher RPM's like a catback exhaust does, but those gains are minimal, 5whp. not worth the money unless you are FI IMO.

 

I heard that you lose power down low with the RT cat

 

I have heard the same and would have to agreed with that train of thought. considering you will lose a little low end torque when adding a catback and gain soem up high, I bet it is the same situation with a high flow or Bigger cat.

 

i feel theres room for an aftermarket cat without sacrificing power... but it will come at a cost. to answer your question in short, there is nothing bolt-on, at the moment, that will help your situation out... unless you are turbo/blown.

 

ok thanks all..i didnt know if there was an E-pro cat for the 2nd gen or not

 

random technology makes a cat that bolts on but i personally wouldn't put it on my car.

 

It's an inexpensive replacement if your OEM CAT goes bad.
