Loud... I Like It Loud!

One thing I've neglected to write about is my car's muffler... Which is funny because it was actually the first mod I made to the car! I had the local Tuffy replace my stock muffler the second day I had the car. The guys at my local Tuffy are great bunch of guys! They stuck a very tough sounding Flow-Pro on. But after a few months it started to look pretty ugly (rusty). So it was time for a change... What I learned from the Flow-Pro was that I wanted a 100% Stainless Steel muffler and tip. The best muffler for the job seemed to be a Magnaflow single axle back. With it's "straight-through" design and a 100% stainless steel, it seemed like it was a good fit for my car... It sounded good and the dyno showed significant gains over the stock muffler. While we never did real testing our conservative estimate is a 10RWHP gain over the stock muffler. So I was very satisfied with the Magnaflow. Good performance and nice sound. But lately I began craving MORE SOUND! The Magnaflow started to sound muffled to me. I really didn't want to go to a dual exhaust but if I had to go to the dual for a better sound, well, I would bite the bullet and put on the duals. It was a real dilemma! So as usual when I need some good Mustang advice, I headed over to MRT ( www.mrt-direct.com ) to seek the wisdom of Mustang Guru Scott Hoag! I explained my situation to Scott. I WANT MORE VOLUME! And that if I had to go to duals I would. Scott told me I wouldn't need to go to duals. He explained that I would just need to put on his MRT single axle-back exhaust. The MRT single axle-back exhaust starts with an Aero-Turbine muffler. You can find more information about this muffler on their website www.aero-turbine.com. I had been on this site before. I remember thinking to myself that the claims that Aero Exhaust was making seemed awfully big! I must say I was very skeptical! But I was willing to listen to Scott and give it a try. What MRT does is take the muffler, fits it with a very nice chrome tip, axle pipe and hangers. Yes, even the hangers are stainless! This is a very high quality piece! So Scott pulled one of the shelf... and I stared at it in disbelief! Oh My Gosh! It looked like something off a rice-mobile! I thought to myself, "Scott's lost it... He's going to put a Fart Can on my car!!!"
Don't worry what it looks like! Well, I mention to Scott that I think the car probably needs a dual setup to get the sound I was looking for. Scott shares his wisdom with me... and here is the lesson I learned. When people see a dual exhaust on a Mustang they expect a big V8 sound... A sound the V6 will never be able to make. So when people hear your car with dual exhausts they'll probably be disappointed. People see the single exhaust and really don't expect much... but put this MRT on and it will really surprise them. Scott says "Let just put this one on and see what you think" I agree to try just the one... but I really don't expect much of a difference over my Magnaflow... So we pull the car inside and Scott gets to work! Before you know it the Magnaflow is out and the MRT is in! Scott fires the car up.. WOW! What a difference! The exhaust note is much deeper... how does such a little muffler make such a big sound? A quick rev and I'm smiling! Scott's 100% right... there is no mistaking it for a V8... but it's amazing the sound that's coming out of that one exhaust pipe! We hop in the car for a quick drive around the block! The car sounds plain awesome! Once again, Scott has installed a great product on my car!!!
Scott wrenching away!		Don't worry, it's not touching
So once again I leave MRT all smiles! Scott and his crew are a great bunch! Great products and their customer service is second to none.... ok... except maybe for Alternative Auto... which brings us to Part 2 of this story! The new MRT muffler certainly improved the car's sound... but what about performance? It appears the Magaflow was good for around 10RWHP. How could the MRT improve on that? Only one way to find out... with a dyno run! So I ask Lidio if he can fit me in for a couple of runs on the dyno. Lidio tells me to come on over. So off to Alternative Auto (www.alternativeauto.com) I go! We get the car strapped on the dyno. Lidio starts the car and immediately smiles at the sound of the new exhaust! Now the car is hot from the 90 minute drive but still manages to make 197RWHP! Not shabby at all! So our usual test procedure (so we can evenly compare to previous runs) is to let the car cool down a bit, which we do. So now is the moment of truth! If you've been following the dyno sheets above you know I've been stuck at 193RWHP for a while now. Lido starts the run. We've already seen a small gain even while the car was hot... so I'm hoping... Lidio finishes the run and the numbers come up! It's a new best for the car without the Zex! Peak HP: 200.8 and Peak TQ: 229! That's 7RWHP gain at peak over the Magaflow! And if you look at the 5500 to 6000 RPM range it's over 10RHWP! This is just plain amazing! So here is the dyno sheet and the video of the run... So the 194 curse has been broken!!!!

PWHEW! This was a long entry... thanks for staying with me! I would just like to wrap this up by saying the MRT exhaust and the Aero-Turbine was much more than I expected, which is very typical of all the products Scott has sold me. Now the MRT exhaust is LOUD and may not be for everyone. But if your looking to turn up the volume and turn some heads then I recommend the MRT exhaust.. It is hands down the best exhaust I've heard for our cars... and all from a single! And here's something I hope you will enjoy: Videos!
