Which one is better? My car is getting one or the other before my bday(Jan. 19) as a present.lol I haven't made a decision yet. Pros vs. Cons?

Hi flow cat=money..and another thing to go bad eventually reonator delete equals 5 bucks for pipe and 3 bucks a peice for 2 clamps....BUt that is nothing i would do as its not good to modify exhausts away from the standards for an exhaust to keep it clean and quiet....

without the resonator your car will sound about as tin like as a ricer, go with the high flow cat such as this one http://performance-curve.com/3goerli...dii608227.aspx

The cat I was looking at was by Magnaflow. Good or bad?

Ive heard they only last about a year or so

depends do you have a 2000+? if so you will need the rear o2 sensor fault tuned off. this one there is no need to do it

mine has been on there for 2 and still going strong

whats the diff between the one u showed me and the one I wanted

My magnaflow is a good 3 years old. No problems. A hi flow cat will deepen the exhaust tone a bit, as well as open up the flow a bit. Removing the res will make it raspy. Mine is still on. You can also go with a larger res for better flow.

i dunno if its any different on Bonnies, but i was running a 3" DP cat and res delete on my GP, it sounded very nice, loud but definitely far from rice
