Straight Pipe Installation - 2004 Ford F-250
Getting my catalytic converter and muffler taken out. I also went from a 3 1/2" Exhaust pipe to a 4". The truck is a 2004 Ford F-250 Lariat Super Duty with a 6.0L Powerstroke. Thanks for watching!

Turbo Exhaust Whistle Test
Here is a test of the turbo Exhaust whistle on my Ford Focus. The turbo Exhaust whistle is supposed to make a regular car sound like it has a turbocharger on it. The turbo Exhaust whistle fits inside of the Exhaust tip on a car, and it makes a whistling noise when you rev up the engine. You can buy a turbo Exhaust whistle for less than ten dollars on eBay. Watch this video review of the turbo Exhaust whistle to see if you need one.





Jeep Grand Cherokee 4.0 Straight Pipe Exhaust
Straight pipe in place of the muffler on my WJ. Stock 4.0 with stock intake/headers/cat/tailpipe. Has a nice sound but is loud and drones inside at 1900-2400 rpm, which the video doesn't capture. Highway cruising is nice and quiet at 55-60 mph, but the interstate at 70 mph/2100 rpm would drive me crazy. I'll almost certainly end up with a Flowmaster 50 Delta Flow to mellow it out a little. I posted another video of a Cherokee I used to own where I did the same thing, but the catalytic converter was much larger and the end result was much more mellow than this. UPDATE: This setup was fun for about 1 week, then was just completely annoying and I hated driving it. It was an unrefined sound, it really howled at 2000 rpm to the point where it hurt your ears, and I also lost torque on the bottom end. I just installed a Dynomax cat-back with their Super turbo muffler and absolutely LOVE IT. Flows better than stock, moved my torque curve back down, has a great looking tailpipe, is barely louder than stock and really has a great tone to it. I've got an initial video posted and will post another in a couple months after the muffler has really broken in.
