Had better...

While this exhaust does sound great on my GXP, I've had better on my old GT. FloMaster makes a nicer exhaust. It's louder and deeper. But as far as the pros for MagnaFlow, it is a deep and mean sound.

I have had this product for nearly a month now and it is awesome! Installation is easy with only a few necessary tweaks to make the pipe fit a little better. The four stainless tips look great and add a unique performance look. Tone is very deep and sounds great at both an idle and when laying into it; but, is still very quite when cruise is set at higher speeds, which is nice. I absolutely love this upgrade and would recommend it to any GXP owner.

Nice product went together easy. Tips are dual 4 inch that look awesome. I was a little disappointed that they didn't include the two bolts and gasket were its bolted to the cat. I'm pretty sure the bolts are 10mm by like an 1 1/2" course tread. The car has a nice deep sound cant wait to it gets broke in.

Excellent product. I've had it for a month now and love it. Great deep rumble at idle and sounds strong when you accelerate hard. Adds 22hp and 14lb/ft of torque. Can definitely feel the difference at higher RPM's.

Nothing performs better, looks better, or sounds better than MagnaFlow Performance Exhaust. The MagnaFlow Research and Development Team invests many hours to ensure their products stay competitive and perform the way they should. MagnaFlow systems feature straight-through flow designs for the ultimate in unrestricted horsepower and torque for big power while maintaining exhaust efficiency. The internal MagnaFlow muffler is designed of stainless steel perforated core, stainless steel wool, and an acoustical absorbent material -- superior to fiberglass (which many other manufacturers use). No baffles, chambers, or louvers. No restrictions at all, just straight-through, wide-open performance with a smooth, deep tone, and each MagnaFlow stainless muffler has a highly polished mirror finish for a show car look. Our systems give a 20% reduction in bends over your O.E.M. system to provide the power you demand.
Most MagnaFlow systems we offer come in three flavors.
  • Street - For those seeking increased performance and better economy, MagnaFlow Street Series Performance Exhaust systems deliver the smooth deep sound you want and the wide-open performance power you need for the ultimate in unrestricted horsepower and torque for big power while maintaining exhaust efficiency. These systems are an engineered balance of interior and exterior noise levels and are tested against SAE j1169 standards.
  • Competition - The MagnaFlow Competition Series Exhaust Systems are designed for those seeking maximum performance, reduced mass and an aggressive exhaust note that demands attention.
  • Race - The MagnaFlow Race Series Exhaust Systems are designed for the ultimate in high performance and the loudest most aggressive racecar sound possible. Race Series exhaust systems remove the restrictive OEM muffler to virtually eliminate backpressure and maximize exhaust flow. The Race Series is recommended for those seeking maximum performance, reduced mass, and a loud aggressive racecar exhaust tone that demands attention.
You choose the sound and attitude you want others to hear.
