VW mufflerectomy (straight pipe exhaust)
Chopped Exhaust on my TDi Polo. A little experiment we did with a £10 piece of steel pipe from ebay. It's a 3 cylinder turbo diesel, so it's got a bit of rumble to the Exhaust now :)

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.
