Thanks for taking the time to look into this thread!
-I recently completed an LS swap on a '96 H/B. When done, I took the car to a muffler shop to install the cat. Said stock cat was given to me by a friend who had it in his '99 EX (turbo), so that cat was probably on its last leg. To my understanding, the EX, SI, LS cats were the same. I wanted it for measuring purposes since I didn't want to weld the cat in place; I wanted to be able to remove it if needed. Now that the swap is done, I don't want to hurt the car by running that cat any longer. Here's my question, what would be a good replacement, bolt on cat? All suggestions will be appreciated. Thanks!

 

you can IM "smsp" on here or call ipsracing.com. you probably need to measure the distance from flange A (header end)to flange B (b pipe) for an exact fit.

 

Thanks for the info.
