Or should I say "stawk"? Either way, here is the comparison.

Here is the stock setup.

sounds very nice!

You'll be able to set off many car alarms with that setup :)

On a side note, if your still looking for stock GT muffs. I'll swap your GXP axlebacks for my GT axlebacks if you want to go more quiet.

Plus I'd love the added noise :)

Dahyum! (new yorker for Damn).

That is a bit louder than I expected. People at work are looking over towards my office.

I can't tell yet. It's been raining for the last 4 days!!! It's supposed to stop tonight...I hope.
I'll give the Butt-O-Meter impressions tomorrow. I'm going to "try" to get an in car video. I have a hair brained idea that I want to try.

It's louder than I expected too. I'm currently trying to figure a way to quiet it down some. It sounds SO good at wide open throttle though...

It's not too bad at all. I drove back from Raleigh which was 1 1/2 hours and it didn't bug me.

I'd try the GT muffs. That is a bit loud. Might wake people in the morning.:dream:

Actually, that is a concern. My daughters bedroom is upstairs adjacent to the garage and I always back in.

They should have offered those muffs on the GT. I wish I had them now as the GT muffs kill my cam sound.

NOW you see what I was talking about lol. The smallest little changes in exhaust flow affect the sound drastically

What have you found out about your exhaust? Have you found a suitable muffler?

WOW! That's beastly! Insane on the sound differences from stock to ARH while retaining the mufflers, now close your eyes and imagine a nice setup of straight through bullet style mufflers.......:devil:!
