Please can any body tell me whats the best magnaflow or corsa exhaut system ... Im looking for preformane not the sound ..

Thanking you in advance .

 

The performance difference between the two is going to be so small it doesnt matter.. But im going to say that i think the magnaflow might have a little more performance. Just because i have yet to see any dyno charts for the corsa.

But like i said the power from the two will be so close no-one would be able to tell.

 

I second everything he said.

 

Magnaflow 3" SI/SO

 

If it's at all possible, do everybody on this site a huge favor, do a baseline dyno run before the exhaust install, then another after and post the results. The most common belief is that changing the muffler is not a performance upgrade itself. Any gains seen by doing this may only be noticable on the dyno and not in the seat of the pants. Truely, a muffler is more for sound whether you want loud or stealth. That being said, changing the muffler is certainly an important mod to make when doing performance upgrades, and usually the first thing anyone does after buying one of these trucks. After all, who wants a quiet truck, not me. The Magnaflows would be the best decision IMHO. Soon I'll be changing from the Flows I currently have back to Mags ASAP.

i'd go magnaflow, you can go si/so, but 95% of people like the look of si/do

 

I've sold about 8 of the corsa exhausts for the f150's and EVERYONE loves it.

Just found this....

Corsa is mellow, not loud. Very high quality. No drone!

 

I just installed a Corsa siso on my truck yesterday. Not loud and not even a hint of drone, just a great sound when you get on it. The exhaust is definitely a quality piece. My wife says it sounds sexy.
