Just installed the headers on (took 2 days and was a PITA) and need a replacement catalytic converter. The current one on the car has a smaller diameter. I need a cat that is 3" in and 3" out. Anyone planning on installing a set of SLP and need extra tips, leave a message.

 

well hear it boils down to money. you can call summit. they have catco for about $99. they will have a walker cat for around $130. then you cold step up and buy like a random tech cat for $200+. or I know mac and I think flowmaster offer a stait pipe replacement fot the cat if you live in an area where emisions don't matter. I put a catco on last time. my engine is still stock. this summer when I put a new motor in it will get a random cat or stait pipe.

 

I'd love any tips/advice you have on installation, if you could email it too me, that would be even better
Thanks
Mo
