Well theres a group buy for Random Technology cats in the groupbuy forum.

Probably would recomend those.

However I do feel like pointing out that your cat is already somewhat of a higher flowing model to begin with, since the type-S models had higher flowing cats then that of the non type S.

I believe they achieved this by making them shorter. Either way I would be interested in taking your cat off your hands.

But just to recap here are your choices:
-stay stock
-Magnaflow cats (400cell per square inch)
-Random Technology cats (300 cells psi)
-I think the stock one might be 350 but there are no concrete numbers on that I just no that the underfloor cat in the new Accords and TL's are 350 but I have no info on the 03 CLS.

You won't gain that much power. Its a waste of money, you might get in trouble, and why pollute the earth?

 

I agree! Do what I did and get a test pipe jk

 

You also want to start posting this stuff in the CL section of our site. Car Talk is for conversations regarding models not covered by Acurazine. So by visiting the CL section of the site, you'll get a ton more info relating specifically to your car.

We can't move topics between the forums, so you'd need to repost if you need more answers. Sorry . But welcome aboard
