Basically the same set up I have. I bought a Jegs 2.5" xpipe and I have the 6.5" long dynomax race bullets. It is loud with no drone however. Everyone who hears it absolutely loves it.

Yup, since installing them...I've been getting nothing but "thumbs up" from other drivers.

Not as deep a tone as I thought they would be. They're basically a one chamber muffler. Low RPM under 3.5k they do sound really good but above that it gets very raspy. Much happier with the current set up. But you don't really know how something is until you try it. Wish I'd went with these mufflers 1st...especially for the price. This set up would have cost a little over $400 to do.

I'll cut somebody a good deal on them if someone wants to buy 'em!

Downloaded a Decible Meter app to my iPhone. On cold start up...peaked at 101 DB's!
I got the app now. I'm waiting for the morning to see what my exhaust level is at cold start. I'll do a test with the car warm to. If this tool works correctly then you should start a post and everyone can add in. Would be nice to have a list of sound levels for each exhaust setup. Cold starts and warm idles would make purchases easier for people.

I use the app this morning on my setup. At cold start my car peak at 101 as well. I have Borla s-type and H pipe. I would have thought that your setup would be louder. Maybe this app isn't the best or maybe most setups are about the same level on cold starts. Could you do a test on your car when it's the car is fully warm up.

Will do. I'll try it later today.

Also, I did mine from about two feet from the drivers side exhaust...just for continuity.

I did a test after driving for 30 minutes. The peak is 92 but jumps for low 80 to 92. Thanks for the heads up on this app. It would be great if more people did this.

Yeah, I think it would be great if others did it also. Exhaust set ups are difficult to judge in terms of loudness...it's really subjective. What maybe loud to others may not be loud to you & me. With doing it this way, you see what the Decible level is and compare to others, a big help when trying to decide on an exhaust system. These systems are not cheap these days and I think the more info folks have the better. It might save folks a lot money from buying an exhaust system that's too loud for their taste or not loud enough. I'm also going to do dB reading from inside the car at highway speed...just something else folks can see.

Plus, I'm pretty sure this App or a similar one is available for both iPhone & Droid phones.
