CAT vs. TEST PIPE??

What would the difference in power be between a high flow cat, and a test pipe? Is it worth to go illegal for the extra horsies?

Thanks

if you go illegal go ahead because you save bout 150 from a hi-flow cat by just doing a str8 pipe

and higher flow, doesn't really matter how much power when it's more performance for less money. of course it's only less $$'s IF you won't get caught and subsequently fined for improper equipment.

its also harder to find a shop who will install a test pipe for you.

all the places i have asked have said HELL NO

haha down here its basiclly a normal thing.. lol
at the muffler shop were all the lil tuners go..
they just ask u do u want the cat or not?
if u say no..
they run full piping with no striaght pipe.. just full piping which i think is better than choppin off the cat and replacing it with a piece of pipe.... no?
i figure that on some cars they have to use a very large diameter compared to the rest of the tubing..
ive seen this too..
thats one reason i wanna get my sisters redone...

i took my car in a couple of months ago to get tested and they wouldn't test it!they said it was to low!:D so they gave me a waiver and sent me on my way!since they won't test it and it's needs a new cat anyway i'm just gonna get someone to make me a test pipe and put it on myself.
