Catless or high flow???

Ok so i just got done getting my new ss/sc exhaust cat back on and iam a lil bit disappointed with the difference lol there wasnt much of one too.
my concern is will going catless hurt anything or should i just give in and get a high flow?

I went catless for a while.
the throttle response is a bit nicer, but in the end, I ate crow, and put a cat in.
these days highflows are built well enough that your not gaining alot by going catless.
and the biggest thing, is it will be ALOT louder.

highflow cat is just a cat with bigger diameter piping around it.....so if ur exhaust system isnt that diameter the cat wont be the restrictive part
