Did mine about 2 weeks ago, I did have to make a coulpe of slits in front, in order to get the cat off, but no big deal. I hate doing exhaust work anyhow. I also installled a MRBP muffler. WOW I am very happy with the sound.



Edit: Sorry, I did not understand your post at first, I did not gut mine; I installed a test pipe it was only about 70 bucks.

Just pull it off set it in the garage nd put in a test pipe.

i agree, i gutted mine and it was a pain. not like a little gasser cat. it was huge. it would be much easier to just replace it.

You can beat it out with a 2'-3' piece of pipe and a sledge. Once you get a few holes in there it will start to come out in chunks. Getting it off is half the battle.

If you put in a test pipe and add the mbrp muffler the drone will drive you nuts.

It will breath better and run cooler. Maybe a little better MPG.

I've read that a flat spot is created, and the drone is not pleasant.

I used a chop saw cut both ends off of factory pipe,then used a 15" long drill bit to drill down through and then a couple of good hits. run a straight pipe through welded back on truck. We have a visual inspection along with a dyno test. Both passed with flying colors. So if anything save the shell for future inspections and they are coming to a state near you.

You must have a different MBRP muffler than me beacuse I have towed my 13-14k 5er around 8-10k miles with my no cat and MBRP setup and not one complaint from me OR the wife. I would do it again in a heartbeat and would recommend it to anyone...

 

[2broke2smoke]

same here, the '03 we traded in had one for about 35k miles ...



nothing but compliments on the deep mellow tone ... no drone

2broke2smoke,



Go price a replacement cat and you will NOT want to gut that thing, they are EXPENSIVE!!!!!!! If you add a MBRP MK96116 and a test pipe you get a complete stainless steel 4 inch system for a really cheap bargain. You can also do the AFE TOM KAT KIT muffler system and use the AFE test pipe they are available in both aluminized and stainless. I just hate to see folks ruin that cat, if you need it down the road you'll be paying the Penta Star a lot of green stuff!

I love the way my truck sounds, no drone problems for me.

My mufller came with the dual kit and is where mbrp splits the exhaust into dual.



I had to add a big 4inch straight through truck muffler up to the very front to tame the drone down to a tolerable level. It is @ least 36icnch long and is perfect empty. When loaded pulling 5'ver and boat [23k] all I can hear is my 2 year old saying get out, get out. It drives him nuts also, even after the other muffler added in.



The MBRP tailpipe hangers SUCK!! and are too light for a VW.
