i recently bought a magnaflow muffer 14829 but after finding out it will cost me from 60-110 to install it to my existing bpipe i decided to go with a cat back instead...it should be alot easier to install cuz it doesnt require welding....i can use a frame lift at my school which will prolly help me with the catback installation.....i have not done anything like this b4 adn i am unexperienced.....is it that hard to remove and install my new exhuast?? how long do u guys think it will take me to do this.....tool i need?
