  1. Delete exhaust resonator

    4th. Generation Chrysler Minivans: 2001-2007
    Yes, I used the search and turned up very few for the 4th gen. And of the ones that did delete, they were looking at adding in a high flow muffler with a straight pipe. This in turn would be LOUD. Not what I'm thinking of doing. I only want to remove the resonator and the 2 pipe turns at...
  2. Catalytic converter - replace it?

    4th. Generation Chrysler Minivans: 2001-2007
    I've got a 2007 T&C, 220k miles, with a plugged cat. I'm considering either replacing it or, *cough* not replacing it *cough. It looks like there are some methods to trick the computer into not throwing a P0420 by using a couple of spark plug defoulers to raise the trailing O2 sensor out of the...
  3. P0404 on 2005 Grand Caravan

    4th. Generation Chrysler Minivans: 2001-2007
    I am getting an intermittent P0404 on a 2005 GC with 150k miles. I just replaced the EGR about 10k ago. I used an aftermarket EGR and I am reading that some users on this forum have had bad experiences. I am due for a plug change (never been done) and I am wondering if that could be part of...
  4. Performance exhaust requests welcomed...

    5th. Generation Chrysler Minivans: 2008-2019
    I have a co-worker who bought a new Wrangler with a 3.6L and he is looking to upgrade his exhaust not for performance gain per say but so he can hear his engine. He has on several occasions looked down at his tach at highway speeds to find he is running 4,000 RPM after using the auto-stick. The...
  5. Excessive pressure in coolant system

    4th. Generation Chrysler Minivans: 2001-2007
    I have a 2002 Dodge grand caravan, 3.3 engine. 137,000 miles. The problem started 2 years ago when top radiator hose blew off going down highway. Filled coolant system back up and put a screw type clamp on hose. From time to time the hose would be very tight and system still was pressured even...
  6. Dual Exhaust, so am I crazy?

    5th. Generation Chrysler Minivans: 2008-2019
    Well the answer is an obvious YES, but I've been thinking about this since I bought the van. On my 2010, it was only a couple months old when I took it to the exhaust shop and had the resonator chopped off and replaced with straight pipe and a Magnaflow stainless tip. I have no idea what the...
  7. cat converter/muffler pipe seperated (see picture)

    3rd Generation Chrysler Minivans: 1996-2000
    Ok guys. Had a LOUD drive home today and took a look under the 99 Plymouth grand voyager to find this (see pic). Looks like the cat pipe has rusted enough to completely separate about a foot in front of the muffler. The shop says it could cost upwards of 800 bucks to fix! The van is not worth...

  9. Ticking Noise on Cold Start--exhaust manifold leak

    5th. Generation Chrysler Minivans: 2008-2019
    I have a 2010 T+C Touring with 30K and I just took it to the dealer for an intermittent ticking noise that could be heard underneath the van near the front tires. If I opened the engine compartment the noise could not heard much at all. Most of the time once the motor was warmed up the sound...
  10. Flowmaster on a 4.0?

    5th. Generation Chrysler Minivans: 2008-2019
    Anyone put a Flowmaster muffler on their 5th gen 4.0 yet? I've been a car guy for decades and I've changed out the exhaust on every vehicle I've owned. This is my first mommy wagon and it's so damn quiet that I can't hear it running. I like to hear my vehicles. This one sounds decent when...
