No prob, ill try to get some good clips this weekend and post. After a few miles, the tone seems to have mellowed a bit. I assume the muffler packing is wearing in. Love it even more now!

LOL, I agree...springs are next on the list (ill hint to the wife for xmas). I was thinking wheels too, but the drop might be all for this car so I can turn my attention back to my bike...

I recently installed rpi exhaust but only did few miles around town.
Do you think that the sound will decrease as I drive it more because it sounds loud to me when i accelerate and my wife and kids are upset. Is there anything to be done to mellow that sound a little bit. I do not want that I was heard from second block or street. From video clips it sounds not that loud. please help I already posted it for classified section or I will return it but do not want to loose lot of money on it
Thanks

RPI makes a Silencer that fits into the exhaust tips, it's easy to install and will smooth out the harshness! Also, you can use one or two of them (one in each exhaust tip) to make it as quiet as you like. Personally, I use one and it is perfect!

Margal, my exhaust seems to have quieted down a good bit since installation. I thought maybe I was just getting used to the sound, but I don't think so, now. It has definitely quieted down some. I have about 600 miles on the muffler and I think the muffler packing material has worn in/settled, leaving a very nice tone. If your family is really disturbed with the noise, FlyingPuck's suggestion with the silencers is your best bet!

I believe Trinity Autosport can get those for you. I looked into this when I first installed my RPI exhaust, but they told me it would take away some of the gained HP....so i left it as is. I've had mine for about 10 months and it does not seem to have gotten any quieter. The noise that's bothering me is more the drone on the inside, not the outside sound. I'm considering buying one silencer like flyingpuck suggested.
