This link shows the different powersticks and powerpacks, available in 16", 25", and 31" lengths. http://www.eadperformance.com/catalo...cPath=42_75_76

I have the medium powerpack installed "against the grain" and it was an important piece of my rasp solution.

Rasp in this vid. As the car in this vid slowly accelerates its makes the dreaded rasp noise.

Powerstick has the crimps, powerpack doesn't. According to them, the powerpack is a little quieter and softer in tone.

so the powerpack would be better for killing the rasp then?

I think they would both do an alright job of killing rasp, one will just be quieter than the other.

i still think that a powerpack would prolly sound better. expically if you install it against the grain

He's right. I would think the powerstick or powerpack would do a little better job just because they are longer than the XR-1. They are also cheaper too

Just wondering if you ever heard back from GMMG about the extra chambered muffler for the I pipe?

i know one thing is for certain the sweet thunder i put in the i-pipe did not work cause i still got rasp at 2k on it hard, and yes i went against the grain on it as well ...but it didnt work thats why i was leaning towards a xr1 style because of the incite on it being capable to quiten it down alittle till you romp on the gas lol, cant evenm pull out on the highway hard cause then it sounds like i got a jackhammer goin off,lolol otherwise it sounds ok......but i am open for ideas so my next question would be should i get a long style of the power pack or stick to put in place of the sweet thunder muffler i have their now???? I'm also curious on how much different these sound...and against the grain aswell.....
