First I would like to say, Mark (2004Denali) it was nice to meet a fellow PTN member. Sorry we could talk longer, maybe next time!
A little history, last November is when I ran my "previous" best, a 15.24 @ 88.22 mph. Back then I had a Magnaflow (12289) muffler using the stock tailpipe with resonator, an Airaid MIT using the stock airbox with a Ram-Air setup and the factory 20's with 275/60R20 tires. Tonight I ran a best of 14.98 @ 90.62 mph. This was with the stock muffler back on, the stock Hemi Hat back on still using the stock airbox with Ram-Air setup and factory 17's with 265/70R17 tires. I think my first bracket race time would have been faster, maybe a 14.95 judging by my 1/8 mile time and mph but I backed off because I was pretty far ahead. I lost in the second round to a fellow Hemi Ram owner, his reaction time was better and it just about equaled our different dial in times, 14.94 (me) vs 15.20 (him). I definitly need an LS rear end, this one legger is worthless. My first run was a 15.61 @ 90.59 mph, I hammered it off the line and spun like a big dog, had to back off the gas and then get back on it. The next three runs I really had to baby it off the line, not getting much of a jump out of the hole at all. When I decide to get another muffler and CAI, I'm getting a Flo-Pro HD muffler (suppose to be almost stock quiet and NO resonation but provide a nice boost in power, ya we'll see)) and a Volant CAI, I want use the Ram-Air set up I made and have an enclosed airbox so the induction noise isn't real loud. Overall I'm happy, made it into the 14's with a stock truck except for the Superchips I have. Not bad for a big ol Quad Cab.

not bad...that's quite a bit faster then the stock reg cab rumble bee that ran against me.

 

Nice runs. The FloPro HD worked miracles on my truck. I hope you see the same results.

 

Thanks! Which number HD did you go with? Any dyno results? Flo Pro claims the 2501 is stock quiet inside the truck and a tad louder outside which is exactly what I'm looking for. Any resonation?

thats a quite nice time i thought it was a bit quick at first but i see you 4x2.

 

Here's my time slip! I'm the left lane, car #3402.

2503 if I remember correctly. Dyno results were wild. It was like 6 rwhp and 28 rwtq. There is an old thread about it on here somewhere. No resonance. One of the best mods I have made.

A buddy of mine has a quad cab Hemi with the Corsa Sport. Great sound, great looks, and no resonance. He loves it.

 

Thanks for the feedback! Where did you get the HD at? I've only found one place on line that sells them and they want $149 for the 2501. Sounds kind of high to me. I'm pretty sure my muffler guy can get one from his wholesale supplier but I'm not sure what the price would be.
Thanks, Jim
