NO MORE DYNOMAX?
Seems Like Dynomax Is No Longer Making Exhaust Systems For Third Gens.

Re: NO MORE DYNOMAX?
I'll look into this and update when I can. I work here at Tenneco and can get a final answer. Sometimes we have website glitches when the data is uploaded, this could be one of those issues.

Re: NO MORE DYNOMAX?
No products have been obsoleted, we are having an issue with the website lookup. If you type in the part numbers in the search bar it will populate. Sorry for the inconvenience, I am working to get it fixed now.

A few short adapters, like most other manufacturers use, could be offered to adapt a 3" intermediate pipe to the large single cat, smaller cats, dual cats, etc. That way you could have one pair of stock style 2.5" exhaust pipes, one 3" in/dual 2.5" out muffler, one intermediate pipe, and less than half a dozen simple adapters, which would cover all the popular thirdgen options. A person with a low output 305 could buy the same kit as someone with a high output 305, and they'd have the option of changing the adapter later when they upgrade the rest of the exhaust. The way things are now, most people aren't going to buy Walker/Dynomax because of the 2.5" reduction at the muffler inlet, and lack of coverage for different models.
Not sure why Summit doesn't seem to stock the 53061/54064 pipes anymore, but if they go away that'd about kill the thirdgen market. It'd also be nice if the dual cat version of the 46669 intermediate pipe came back.
Stock style early and late thirdgen tailpipes would be nice too. The currently offered tail pipes look sorta like the early thirdgens, but they also look to be crush bent.
Anyway, just rambling.

Re: NO MORE DYNOMAX?
Trust me, I hear you. There are a lot of things going on here at Tenneco, especially with the acquisition of Federal Mogul. Not to mention, Tenneco is a very large company and things tend to move slowly. I will try and mention something when the opportunity presents itself. These kits are not top sellers though, so others tend to take precedent.

Re: NO MORE DYNOMAX?
The Dynomax catalog still does not load for thirdgens and Rockauto appears to be selling out the last of their Dynomax kits for our cars. What's up?

Re: NO MORE DYNOMAX?
Seems Like Walker/Dynomax Has Also Dropped The Intermediate Pipe For The High Output L69 Engine With The 4-Bolt Cat,It's No Longer Listed On Rock Auto.

Re: NO MORE DYNOMAX?
good thing I bought mine earlier this year. I wanted something that looked stock and Dynomax was the only option I could find. I guess this will leave stock looking options

Re: NO MORE DYNOMAX?
I wish the full print catalogs were more available/more easily available.
Any chance of whispering in the right ear to get some additional exhaust options? Specifically all the thirdgen catbacks are 2.5" at the muffler inlet. If a 3" option was available, it'd be a lot more popular. The late 4th gen intermediate pipes are really close, it wouldn't take much to put together a 3" system.
A few short adapters, like most other manufacturers use, could be offered to adapt a 3" intermediate pipe to the large single cat, smaller cats, dual cats, etc. That way you could have one pair of stock style 2.5" exhaust pipes, one 3" in/dual 2.5" out muffler, one intermediate pipe, and less than half a dozen simple adapters, which would cover all the popular thirdgen options.

2- the Dynomax end did aftermarket, and even if it makes sense to you for a part with this end and that end to existing, if it didn't make sense in a kit that covered a broad year range AND wasn't already available as an OEM replacement part then it doesn't make sense to make it.
3- These cars were never that popular and are not that likely to be. I like them, you like yours, but the rest of the world... nope, not really. Most of these things are 30-36years old now. Unless it's as popular as a 1st gen Camaro it's just not going to have the parts availability. Hell, first gen Mustangs are likely the second most popular "muscle cars" out there and exhaust parts selection sucks for them. Try to find a good performance aftermarket with oversize pipes exhaust for a first gen Mustang with factory track pack (the thing that gets in the way is staggered shocks), there is nothing that I know of, and you can't just buy different pipes from different places like you can for 3rd gens. Honestly, we're still pretty well off. 3rd gens are still riding on the fact that they were competition for the popular fox mustang when new and that a lot of 4th gen parts also fit... because of that we end up with better parts availability than the car's popularity deserves. More and more, get used to making stuff if you want it.
That said, most of your complaints/requests are easily worked around, like the fact that many intermediate pipes neck down to 2.5" (because the mufflers on the factory performance exhaust slid over a 2.5" pipe)- just lop the 2.5" end off and you're left with a 2.75" pipe (factory performance, this slip fits into a 3" pipe) or a 3" pipe with an aftermarket performance intermediate pipe. In a lot of cases the pipes are still long enough that you can make things fit, and it's not a big problem to either use a band clamp or to weld a small straight section in there if necessary.
