Looking to replace the factory cat with a high flow one what is the best one I have a stock carb L69 305 5 speed stock exhaust. I want a cat that I will be able to use if I decide to go to headers in the future. the current cat is rattling/starting to break up

 

I have the same exact car as you. I have a carsound cat. They are made by magnaflow. Flows like Random Tech. but half the price.

 

Where did you get yours/what did you pay?

 

I remember I payed about 125 shipped. I got it somewhere off line but I don't remember. Just do a search in google for it. I also know that Jegs sells them.

 

did it give your car more power, or did it just make it louder

 

One call does it all, one click gets it quick. Good old Jegs

 

You can get the universal 3" catco cats from a guy on ebay, I paid $46.

 

Stay away from the one size fits every car. More installation problems then you want.

 

I definitely want a bolt on.

 

would i have a problem if lets say i get a high flow cat but my y-pipe is 2 1/4 and my catback is 2 1/2 ?

 

Not as long as the flange is the same. mine has a square flange on both sides with 4 bolts either side.
