it would without a doubt be loud, and probably too much so.

that would be great! is it like obnoxious loud or just really really agressive loud?

Pretty loud on cold start. once it idles down, and car is idling, its not much louder than the stock headers and H pipe. Driving around like a normal person drives, its not real loud, but you can deffinitly hear the difference. once you jump on the gas, heads will turn and people wish they had a car that [email protected].... I really love it.
Get compliments all the time.

I do start it up at 0430 in the morning to go to work, none of my neighborss have complained yet. so it must not be too obnoxious..

lol nice description. that sounds alot like what i want. it can idle pretty loud i guess, but if im just coasting or just putting through down on very low rpm id like it just a bit louder then stock. but when i rip on it. I want it to scream!

It's going to be loud. With high flow cats it will be more controllable but if you run off road mid pipe, look out...

This is one of our memeber's cars. Not his setup anymore but this was factory headers, off road x pipe, resonator delete, and Roush Axle Backs. Needless to say, a very serious noise...

wow that sounds AWSOME! now picture this, kooks headers, cat delete, 3 inch resos, and kooks h pipe meaning QUAD EXHAUST!! :)

now talk about loud lol

You're going to lose some tonal quality the way the Roush axle backs are designed. They sound good, don't get me wrong but they get out of control FAST with the right setup. The rasp is going to be mind boggling. You will lose some of deep tone because the mid and high range frequencies are going to way overpower the full range. It seriously will sound like an NHRA Super Stock, because...well...that's what a lot of super stock setups are like :bigthumbsup. But if that's your cup of tea, more power to you.

This is a car with ARH headers, matching off road X pipe, and a Magnaflow Competition catback.

The Competition catback (from my own personal experience) can be loud if you want ti to be. It can also be relatively subtle.

The Roush axle backs will be quite louder.

Remember that the Roush axle back is just that and this car has the full catback. Magnaflow's Competition axle back is a true muffler delete so if you go that route, it will be even louder. And that basically you might as well not have any exhaust whatsoever. That is modified Harley loud, an in my opinion, stupid.

If you get headers and o/r x-pipe with any blow through muffler this car get real loud real fast. It's sounds good at idle and revving but you can't understand the sound it makes under load. It will scream and trumpet and it's fairly high pitched. If you're looking for a deep tone, youre not gonna get it going that route.

well since I will be going with the kooks h pipe that will convert my system to quad exhaust, im guessing that will also play a roll in how it sounds?
