Very stupid. Their mufflers ladies...they're not going to make a big HP difference no matter what.Crush said:they dont call em BLOWMASTERs for nothing. Magnaflow dynoed more hp, thats why it pulls harder

Post these dyno sheets please...I would love to see themCrush said:They dynoed MORE hp, and they dont sound like uncle Jed's Pick-up
1+1 = Magnaflow is better
I gained like 25HP when I welded in my Flows....or was that from the sticker I put on....either way I noticed a HUGE diff. WTF, mufflers really don't do anything but change the sound. I welded in the Flows in mine and noticed a grand total of 0 gain. I had to put the Prochamber on to notice a gain. If you want to gain HP from exhaust get a mid pipe and a cat-back. Mufflers won't give you anything but sound.Ryan02Stang said:Post these dyno sheets please...I would love to see them
I think what it comes down to is Magnaflow stickers actually give more horsepower than the Flowmaster stickers.DELOS02GT said:I gained like 25HP when I welded in my Flows....or was that from the sticker I put on....either way I noticed a HUGE diff.

haha...the link doesn't work. But in all honesty do you think that Magnaflow is NOT going to say they are better than Flowmaster and vice versa. I have yet to see a manufacturer's hp claims be totally realistic.Crush said:Magnaflow

Flowmaster doesnt provide any information.
Just a start.
What all does the 15644 system consist of???trinity_gt said:Magnaflow's website says that their 15644 system nets 22.9 rwHP and 25.4 ft-lbs. The 15644 is for the Cobra and I'd actually believe that, especially the blower motor. I wish there were honest, real plots of before and after gains on a stock or near-stock 99+ GT to go by.
So the ONLY thing your friend did to the car was take out the 2 flowmaster mufflers and put in 2 magnapacks??? This was same day, same condition, no other mods???Defleshed said:you will gain moderate amounts of horsepower from swapping out flowmasters on a blown car. my friend's 9psi blown kenne bell made 31 more hp at the rear wheel with magnapacks vs his old delta blow-blowmasters. on an N/A i dont think it makes a huge difference. a full catback system usually runs 5 horsepower over stock to the rear wheels, unless the stock was really shtty. and in the long run, 5 horsepower really isnt going to matter much, when more important things come into play while racing... such as weight, and how good of a driver you are
