3in catalytic converter I am trying to peice together an exhaust for my 98 TA and I have some long tube headers from TSP and I was wondering if there is a 3in to 3in catalytic converter out there.

You also want a metallic core.
Go thunderbolts.
Can't beat them for the money.
Fitment is great.

Oh yeah, did I mention they're a fraction of the cost of the other ones out there?

I found this to be an ok read regarding the subject:

FWIW I run dual ceramic Magnaflow cats on my truck. They seem to do great for passing emissions but the ceramic inside is brittle so they break quite easy as mentioned above. I just had one of my cats replaced last week because I noticed a slight exhaust rattle awhile back. After removal I noticed half of the ceramic matrix was gone. Apparently I blew it all out of the exhaust doing some WOT passes or something.
If I had to do it again I would probably use the metallic catalytic converters. Come to think of it, I may try out the metallic cats next time around if I can find some that are the same length as my current cats.

Damn thanks guys. MattaxFatal your a badass I spent months looking for good cheap cats. The set up will be on a 98 Trans Am with 3" TSP LT headers I guess those Thunderbolt cats and a TSP X pipe with bullet mufflers.

Question for those with the metallic core cats - do they still do a good job of cutting out rasp? I've found some cats that are 200 cell (looks like the Thunderbolts are 300 cell), but I want to make sure it takes care of the sound issue just like a ceramic core converter does.
