Engine/Transmission (1998.5 - 2002) Does anyone sell a 4" chrome turnout stack or should I go 5"?

[VIPERBLUELX]

I have ran my own 4" through the bed single stack on my truck and I've currently just got regular 4" aluminized as my stack pipe and that's not cutting it anymore. I was thinking of just putting a 4" chrome turnout stack on it but I can't seem to find anything? Anyone know a source?

I beleive dynaflex or grand rock sell them. if your going to change it I would definately step up to the 5". if not howlong do you need. I think i might actually have one or 2 laying around.

Only has to be about 30" tall, if you have one longer I can just cut it to length. If you've got a 4" that would be great, let me know.

If he doesn't have one... . check your local Peterbilt shop or Cummins shop. I know the peterbilt shop up here carries them in different lengths. Any of the big truck stores usually stock them. 4" is a standard size on Mack trucks too. Hope this helps.

You can get 4" stacks in turn outs, 45 mitre, and straight cuts.

I would go with the MBRP 4" turnout stacks. They are 36" long and are made of 304 stainless. They also carry a lifetime warranty. I can get you a set of them for $235 shipped
