I was in a similar situation....today i do the purchase.....

I think both are great, but in performance gains theres no much information of any of those systems....:dunno:

Both are great systems and produce roughly equivalent gains of around 7 to 12 HP area. They are so close that you would not be able to tell/feel the difference, but that goes for pretty much all the options for the exhaust. So, really, it comes down to three things: cost, look, and sound. I use to have the 7ism, but sold it to a friend and went with the Magnaflow instead myself.

PM me if you would like a price on one of the GReddy exhausts. We beat any price.

It depends on which Greddy exhaust you're talking about as well. There's the SE and the Ti-C.

If you were looking at the Greddy SE vs the 7ism exhaust, it makes sense why the 7ism would make more power. The Greddy SE is just an axle-back.

However, the Greddy Ti-C would be on par if not exceeding the 7ism in power. It's an extremely efficient setup designed for power.

7ism has street version and racing version, which do you prefer?

Racing version is bit noise at 2,000 rpm from customer's comment (3.8 a/t), but it shows more power.

If average rpm use on 3,000 rpm, you can avoid the noise.

I have had the Greddy TI-C on since Sept. and its awesome. Its a few bucks more, but its worth it. Looks great, sounds sweet, and actually makes power. And they have a good warranty. No PITA install, no rasp, and no fitment issues whatsoever. It also comes with silencers if you want to keep it quiet. If you search the exhaust on here you'll see the pics I posted about it.
