take it to a muffler shop is the best for you, you can always find a muffler shop in any area that will do something like that for 50-60 bucks to weld it up. Me personally, i had my cat just cut out completely and put in a straight pipe, with flowmaster 44's. But getting them welded is in your best interest... i never believed in clamps myself

 

Should i stop driving the car, ive heard it can over heat my car? even though my average temps are 199-223 and everything is working properly cooling wise, I keep my maintenance to the max. :bomb:

You will be fine driving the car. This concern applies to 2 stroke engines where backpressure changes also influence the scavenging process, which in this case would severely lean out the A/F mixture and cause some major heat issues like melting pistons.

Listen man, i drive the same car except mine is a (Sport) so i dont have the stock cd player like you did, but the reason why my cat was replaced with a straight pipe was because it was clogged to hell... and guess what... i was driving it like that MONTHS before replacement just like that and nothing bad EVER happened. I have never heard personally of overheating in result or root cause of a clogged cat, or bad exhaust. I wouldnt worry about much. A high flow cat is similar to what a straight pipe would do, so your heading in the right direction. Google some muffler shops in your area, call for quotes, just tell them "i need my cat cut out and this one welded in..." dont forget to tell them, "IM PROVIDING MY OWN PARTS". just ask them to cut and weld that only takes as long as an oil change. Should only cost around 50-60 bucks and you'll have a dramatic noticable change in sound, as well as feel of the car. (car will feel like its breathing ALOT easier!) Lots of debates are out there as well of "performance HP increases due to cat delete/high flow cat". This subject will always be up for debate, as i personally think though? the more air you can take in, and the more air you can push out will always increase HP. :devil:

 

well the whole idea was some jackass on the internet, youtube to be exact. the only reason why i found that myth is because i searched the internet to get a better understanding how the cat works... i thought id throw it out there and see the response cause i wasnt exactly sure if it even dealed with our cars. he was saying if it was clogged there would be more heat going back to the motor and whatnot... Ive owned my caddy since the day i got my license and it was family owned before. i do all the work on my car myself. even exhaust haha... the mechanics in my area are money hungry goofs that half ass everything.

Thanks power caddy for pointing that out. Its just now everyone is turning there heads when they hear my car, its alot louder.



oh yeah, in your second post, i kick myself in the head all the time saying i should have got a set of flowmasters... dynomaxes sound good but to be honest they sound exactly the same as my last stock mufflers... i wanted a deep meaner growl. I wish i could just do a straight pipe all the way back but damn Pennsylvania has emission tests and doesnt let you run a car without a cat.

 

you must be getting codes with no O2 sensors for cat? i hate seeing a CEL every time i drive car.

 

No sir, you OBDII guys get O2 sensors at the cat, we dont.. so no "check engine light"

That sucks man, well you could always cut off the cat "shield" and tac weld it onto a straight pipe to make it "look like" its actually a cat.
Thats what me and my buddies used to do when we all drove camaro's and trans ams back in my Chicago F-Body club i was in.
