Do these fit our cars? I here they offer great gains. I really want to do something with the cat. Everytime i start a thread about it people say search, and i have and found nothing. Are there any hi flow cats available for our cars other than RT? Thank you

 

our exhaust system on the Second gen TL is very different from the Third gen. We have one Cat while they have a warm up cat, pre-cat, and the same old cat cat that we have.

I think that's right, anyway, no we don't have something like the e-shift procats. It's unnecessary for our car.

 

So how could we mod our cats, is there anyway? Im willing try anything but a test pipe.

 

RT cat. Contact Excelerate for them.

 

If you're not willing to do a test pipe the best you can do is a high flow cat. Random Technology makes an application for our cars. Talk to Excelerate or Heel Toe. They are the best vendors on our forum.

 

anybody know offhand what the inlet/outlet sizes are on the RT High flow cat???

 

I would ask Excelerate or check the Random Technology website.

 

but i have a type s. i was told they dont fit the type s

 

theyll fit a type s.... with minor modificatons, you need to get an extension for the o2 sensor and drill out the holes on the flanges a little bit

 

it fits but you'll bottle neck the exhaust system. That cat was made for TLPs so the piping size works compliments their exhaust size. Just buy a universal one and have flanges welded to it and install it. Cost less than the RT cat too.

 

also if you are sketical about getting an exhaust shop to do it, you can hit up p2r. They have made a few things for me and my boy for good prices.

 

Good call L's. Those universal ones will save you a ton.

 

yo L's you dont happen to know the inlet/oulet sizes on the RT cat do you?
