Should I punch out cat or replace it????

[94camaro25]

I have a 94 camaro w/ 3.4L and the cat is bad. It rattles at every stop sign, stop light, you get the picture!! I was talking to a local who does exhaust work and he will put on a "high flow" cat for $195.00. To me, thats a good deal, since I can't seem to find them less then $185.00. Here's the deal, my friends are telling me not to go get a new one and go ahead and punch out the old core. What are the pro's and con's with removing the core from a cat? Will it affect the motor since there will be no back pressure (My motor has approx 150,000!)?? Has anyone punched their core out?? Well, before I do something I'll wait to hear what you guys say....thanks :rolleyes:

I say go with a high flow cat for several reasons: first off, you'll pass emissions testing (if your state does that) second, you won't kill the environment (and yourself) by spewing fumes, and now the most important reasons: it'll sound better (not raspy, like a tin can) and you won't lose power because if you have little or no modifications, you will need a little bit of backpressure in there. High flow ALL THE WAY.

search frist but

you can punch your cat out and it wont hurt and thing but your service engine soon light will come on.

195 seems steep you can get a high flow cat for like 50 from Summit and just have him weld it in. ;)

OKay, I deffinetly do not want a "tin can" sound, I got a flow master w/ 3.5 tips which sound nice as it is. Yeah, the enviroment things is a factor. But I really dont want any service engine soon lights on, thats for sure. I have little mods done now and plan on doing alot this summer, so a high flow seems like a way to go.

Does anyone sell a high flow that is a direct bolt on so I don't have to weld??? Who makes a good high flow cat??

Viper: I'm gonna check out Summit, thanks...

Carsound cats are high quality...and you should get it welded...no leaks that way.

WHOLEY HELL $195 is a RIP OFF! I got a magnaflow high flow car AND custom 3" INSTALLED for $175!

Find a better deal on that cat if you can man... they seriously take a couple minutes to put in, cut out the old one and weld in the new one... should NOT cost you $195!

Viper- you the man!! I called summit and they sold me the high flow catalytic converter for $55.69. How much do you think is a reasonable price to have someone weld it in for me? Thanks man.

For all that need to know- part # CC06906 55.69

I got a question. Does the stock converter come with o2 bongs or air injectors?
