The SRT-10 tailpipe I bought arrived and I had it installed this morning along with a SI/DO Dynomax Super Turbo muffler #17776. The Flowmaster 50 HD I had was just to loud for me, this is so much better. It's stock quiet, maybe one or two decibals louder. The SRT-10 muffler has offset inlets and outlets so the muffler was installed at an angle to line up with the SRT-10 tailpipe. The 05 SRT-10's come with a factory resonator which is what I wanted to keep interior noise down. Here's a few pics!

Looks great!

 

Butt dyno or track #s????

No track numbers but butt dyno said it feels good, almost better. Pulling out of the muffler shop, it felt like my butt was planted in the seat more than with the Flowmaster. It's so much quieter so I wasn't influenced by the exhaust note I was hearing, or not hearing in this case. Driving on the freeway last night, it seemed to go up the hills a little better also, no more slowing down a tad. So far, I really like. I've come the conclusion, that this is probably the best it's going to get. I would like it a tad louder but after a month of way to loud, quieter is definitly better than louder for me.
