Episode Synopsis

Over a year and 29 episodes ago, Motorz TV started with a pilot episode where we installed a MagnaFlow exhaust on our project Ford F-150 pickup truck. Man, a lot has changed since then. It was called “Truckblog TV” back then, a spinoff concept based on my truck blog called Truckblog.com.

I was asked by MagnaFlow to write an article for Truckblog, much like I have been doing for the past 10 years or so. I had been thinking about trying a video install format for a while, and so Jason and I just went for it–the first episode of MOTORZ TV was born. That pilot also happens to be the only episode where we published a written install as well, available at Truckblog (and the only episode where I wear shorts and a t-shirt!)

Watch episode #1 and then watch this new episode (#29) and you’ll see how far we’ve come over the past year!

As for installation, it’s pretty simple. Jack up your car (or put it on a lift) and remove the old exhaust, then put on the new one. We really had to jack our Mustang up high in order to put the new over-the-axle pipes on, which is why I highly recommend (twice in this episode) to take your vehicle to a shop and use a lift. It’s mainly a safety concern… you have to lift it extremely high so if you do attempt it at home, be sure to secure the front with wheel blocks, and use strong jack stands, and just be very very careful. Some exhausts come in three sections (like the F-150 install), but this Mustang exhaust is only in two parts which increases the difficulty level of the install.

One part of the install that can be very time consuming is the alignment. The Mustang has two exhaust cutouts in the bumper for the tips to sit just right. In order to align them you have to make sure that all your bolts are loose, then align the tip… tighten, align, tighten, etc. It can be quite a struggle, so just be sure to take your time… just when you think it’s not going to fit, you wiggle or bang a pipe just right and it settles into place–right where you want it!

  1. Hey I have a question, do you believe this is the best exhaust possible or have you not heard the stinger or frpp exhaust before on a mustang? I just bought an 08 and I want the loudest exhaust possible but horse too.

  4. stock one sounded better to me. i like the popping noise when the rpms drop and you dont get it very much on the aftermarket

  5. if your saying you need a hoist to even get the over the axle on in the first place. why the hell cut the original pips.. what. take it all off. drive to your nearest machanic and get them to do the rest.. -_-. not very smart

  7. Love the videos ! they have helped me a lot with my mustang, i was wondering if you guys have done or plan on doing a video on installing headers .

  8. Thank you for watching! Headers on a Mustang are a little tricky, but we’ll see if we can pull that one off in a future episode!

  9. I’m wondering if exhaust clamps will have leaks? I’m planning in putting in magma flow mufflers on my mustang, I know how to weld and am doing a welding course but don’t feel comfortable welding under my car with the gas lines and tank etc

  10. i dont own a mustang and probably never will but i like the fact you did this on the floor most people dont own lifts

  11. Thank you for the great comment! We do our best to keep things ‘real’ because we realize most guys don’t have a lift in their garage!

  12. This is what I have on my 06 GT convertible. It doesn’t drone at cruising speeds like a chambered muffler. It’s more of a mellow old school glasspack tone.
