It will not matter, both will give you 9hp max, nothing noticeable.

Slowmaster will hurt low end , Magnaflow or Dynomax .

How? Proof?

Common knowledge , seen it several times , Tuner .

Blowmaster is just a name , don't have the testing report that was done on exhaust but will try and get it from my other computer

How a muffler alone is going to hurt low end performance enough to cause it to be noticeable (20 ft lbs of tq. or so I'd imagine) is beyond me. I'd have to see a dyno graph of a before and after, I just didn't feel anything noticeable after my cat back install, good or bad.

except sound, That was good. I cant wait to get back home and get my super44 on, see how it sounds...The guys said its loud.

Yes the sound was good. I'm really wanting to take off my 4" tips, because before I had them on it had more of a deep rumble, after the tips it has a hollow, more mellow sound. If I didn't spend so much on them I would have taken them off a long time ago.

The 44's are supposed to be louder than the original 40's. You've gotta get a sound clip after their on.

I'll try my best, I'm sure the wife wont complain if I tell her I need to buy a new video camera to put up a sound clip. She'd just be all over that, I would use it once and than she'd claim it as hers after.

Sounds like my digital camera.......my CD-R's, my mountain dew, my dish network, your not alone!!!

Super 44 is the winner! I heard them on a truck & they sound amazing, I bought two 3" super 44s for my truck & this weekend i'm hoping to have them installed if my buddy is free and able to help. Super 44 is better than the Super 40 and original 40, its much smaller case allows for a much more louder aggressive sound on the throttle, and it gives off a real deep idle, I cant wait for this weekend!

Heres a pic with 1 of my Super 44s & a Super 40 that I never installed to compare, the Super 44 might cost a few more bucks than a 40, but its well worth it

I cant wait, I just have to get home first, I'm stuck here in Halifax NS 6000miles from home, doing some training for my job in the Navy.

Necessary evil, but its sucks a lot. I hate this place. Plus I am not sailing down state side, so now I can't enjoy our dollar trading on par with the US. Best time ever to buy parts for the truck, and I'm missing it...I'm sure we wont be trading this high for long.

None the less, the training is awesome, I get to play with, and fix some really cool toys.

so would i lose any low end with the super 44 single in dual out, would i lose any with the 14" magnaflow, would one have less loss/more gain than the other ??
