I called Shell Valley today. The guy I talked to said 3" but didn't sound to sure of himself. I thought 2 1/4 maybe 2 1/2. Dana was not in so I will call later.

Not sure exactly what information you're seeking, but here are measurements from my '92 Shell Valley. Primary pipes are 2" OD. They merge into a collector which is 3.5" OD. The muffler has an OD of 4" and the turnout is 3.5".

Thanks Dirty,
What I was looking for was ID. of the baffle. And after callind and talking to Dana he said 2 1/8.

littlewave 12-28-2012 10:06 AM
Now my next question. Is 2 1/8 big enough to flow 425hp?

Thanks guys..:confused:

I'd say no. Most say you loose 100 HP through the usually restrictive side pipes.
I'm on my second set of Shell Valley side pipes and I'm tired of them developing the baffle rattle. My next set will have 3" classic chambered inserts. Do a search here and there is lots of info on these.

How long did your first set last? Maybe I will just run them this summer and change them out next winter. They are at the coaters right now.


Thanks for the info.

mickmate 12-28-2012 11:06 AM
That's too restrictive you would be near 100 HP loss with them.

I highly recommend these guys.

My first set lasted about 5k miles before the baffle broke loose and the second set only got maybe 2k miles before the same problem. When I called Dana, he seemed surprised like this had never happened before. But from reading here and other forums, I know that's not true. I don't want to say they are cheap POS, well I guess I just did.:rolleyes:
Mickmate is right on his recommendation!

littlewave 12-28-2012 11:25 AM
Ok guys. Thanks..
