I just got high flow aftermarket catalytic converters. They look a little smaller than the originals. Is that normal?

 

I looked at after markets .... and after speaking with the local euro garage since my car has no post cat 02 sensors I'm just gonna gut em.

 

where/ what brand did you get? How much? I would like to do that with mine but not sure if its worth the money. Can you notice any performance gains. How do they fit up compared with oem? sorry for so many questions but it seems like Ive seen threads about this a dozen times and no one ever gives definitive answers.

Thanks, Matt.

 

I got a pair of catco brand of ebay for 485. Has pre cats and cats that bolt on. Seller got a lot of positive feedback from selling the same part before. I don't know of any gains. I just hope they work. Everything looks like it would line up from underneath. The cats are just a little bit smaller. I will have them put on wednesday so I'll let you guys know. BTW if you change your cats keep the original. The local shop will give me 200 for my used ones.
