hi. i am panning on purchasing a smog legal high flow cat from this website: www.mufflertech.com
has anyone here had any experience with them? are they a reputable company to deal with and do you guys think its a good idea for me to purchase the cat to begin with. i already have the i/h/e combo and i just thought that adding the hi-flo cat would complete the system. if there are any disavantages to this, please let me know. thanks!
