I'm allergic to cats, thats why I run with my ASP Exhaust (Midpipe/Catback in One)

Are both the N-Tech and Bonez high flow cats true 3" ID? For some reason I thought I once read that the Bonez high flow cat is 2.5" ID and the N-Tech high flow cat is 3" ID.

i don't know about the size but sound of ntech compared to stock is noticeable louder. not midpipe loud though. i dig it.
has everyone been passing emissions with just ntech? i forget which reading it was but the guy put down one point under the limit, i thought he might of done me a favor

I prefer the Random Technology cat. Flows awesome from personal experiences on a few different cars, RX-7s and Supras included. Big 3" ID and seems to run really clean... just a couple decibles quiet compared to a midpipe.

question --- If the N-tech hi-flow cat flows 96% as well as a midpipe, then why wouldn't it cause boost creeps as midpipes do??? Thanks in advance.

The N-Tech can be used without the air pump. It comes with the port plugged. If you want to use the air pump, you'll need to have a pipe welded on. If you need to pass inspection, you probably need to keep the air pump.
See pics and read info about the N-Tech cat here:

i just asked this on another similar thread, but would the borla xr1 muffler on a mp be quieter than a high flowing cat? if so, i would definitely ditch my cat for the borla mufflers and have the advantage of a straight through pipe, without fear of being pulled over for noise pollution. (yes, i know if i DID get pulled over, i'd be dead meat for no cat)
