resenator leaking, need opinions on fix please
my resenator has a leak/hole on the top under the shroud and i am trying to decide what to do. Am i better off patching it? cutting off the resonator and putting in a new one? straight pipe? new exhaust system from the cat back? trying to weigh cost vs ease and life of parts. i appreciate any and all opinions
a muffler shop can take it off and put on a new one or remove it completly opon request. if you have a pype put in its place it will give itmore of a throter sound. rill you deside or when it comes for a new moffler it will be your choice as well put on a cat back or muffler.i will just put on a pype where the resinator is imp it is what you choose is what the end resolt is what you perfer. what i would do is go with out and put a pype in till the time comes for a complet replacement of the system

My res rotted all along where it was seamed. I first had a shop replace it with an aftermarket one. I bought the Monte in '08 with 52,000 on it, it now has 62,000. This happened when I first bought it. In less then 10,000 miles I had it into the shop 4 times for the res (the initial time, another time due to noise, a 3rd time time they swapped the res for another res).
By the 4th time I was tired of dealing with this (even though it was all under warranty, this was getting silly). I know a couple others who have w-bodies and had their res replaced at the same shop, had ZERO problems. The shop worked with me, so I have no complaints.
As of the 4th visit (which was this past spring), I had them remove the res and just put in a piece of pipe. DONE! One less thing to worry about it.
Everyone says the exhaust is "drony". Personally, I think it sounds almost the same, just a little tinny. In my opinion, no big deal. Worth it for the added performance AND more importantly, not having the hassle to deal with aftermarket resonators.

Another option is to replace the resonator with a glasspack muffler and retain the stock mufflers. I replaced my resonator with a Magnaflow glasspack and I think it sounds great. It's slightly louder than stock at idle, under acceleration and at cruise with a mellow tone to it. No drone whatsoever.

Now thats a good Idea
Yea I've been looking at the magnaflows or a cherry bomb. What size glasspack did u get? Cuz I have a 6th Gen and the thing is huge. I measured it and the resenator is around 30"long. So would I probably need a small length of pipe just in case its not a perfect fit?
I used the Dynomax/Walker flange #41806 (<- link) and the Magnaflow #18145 (<- link) glasspack and it worked out to the same length as the OE resonator. I did the install (along with a new downpipe/cat) at a friend's shop. We did have to use a pipe expander on the extension pipe behind the glasspack, but a reducer would also work.
