I plan to do before and after with the Magnaflow P/N 16515. Should be a week or so.

What about the Magnaflow 16890 with 2 mufflers and 2 resonators? Anyone running this system?

I just ordered the Magnaflow 16510 system with 2 mufflers and 2 resonators. This system has a true x-pipe and re-uses the stock tips.

That was one of the reason I skipped the Corsa. They didn't put a single dyno graph of their system up on their site. It made me wonder if they even tested it.

I don't have all my notes any more.. computer died... but here are some quick search results. I've also sent them an email speedy, I agree the numbers should be easy to get and posted on the site. I realize mfgrs can slant these 7 ways from sunday but still..

NOTE: my personal experience over the years would lead me to say 10 - 16 hp on a cat back... but that's just me....

They have to be careful slanting numbers too much. This is the age of the internet and people like me actually test things to see if they match or come close to manufacturer claims. If not they get called out on my website for all to see not to mention the forums

I would think 15 or so HP is reasonable from a cat back.

Yea, goto to love the internet. I guess another issue in posting hp 'gains' is that depends soooo much on the stock exhaust. The Challenger is supposed to flow fairly good from the factory so I'm dying to see what you get on your runs..

Giving numbers as an average percentage has similar issues. What you are doing is truly the best. I only wish I had reasonable access around where I live. I'd have loved to do before and afters for mine.. I believe any numbers need to be on a per car. IE. Mfr a gets 12 HP gain using mdl xxxx on a 09 Challenger 5.7 with cia... etc...
