hey ive searched and am still a little undecided so i need some help. i put in my magnaflows with custom 2.5 inch pipes and gutted my cat converter about year and half ago. but right now i have a leak in my exhaust, and i was going to fix it but decided i was tired of the sound from my car (plus a cop attention getter) so i was thinking, wut kind of high flow cat should i get? and also i still have the other two resonators in tact,

should i gut those two resonators after putting in a new aftermarket cat, or leave it?
will sound remain same if i gut two resonators and put in new cat?
will it be too quiet if i keep resonators and add high flow cat?

any help is appreciated thanks.

I have a few sets of Random Tech 2 1/2 inch cats for sale. PM me if you are interested. Random cats out flow others as much as 30-40%. He is right they are the best. They are what is called Metal substrrate Cats. Means the inside is not Ceramic but Stainless Steel.. They are very expensive tho retail. If interested let me know.

what is a good flowing exhuast & size dimensions for a NA-T sc300 and is the QUIETEST? I want something as quiet as possible since this will be for a daily driver.

You can find metallic substrate cats for around 200. RT and a few other companies make them. The material is almost the same from what i've seen in the different brands.

The nice thing about the metallic substrate ones is that you dont need an airpump.
