Had my truck since new and haven't changed anything from stock but bumpers. I been reading for quite awhile on this site about reasons to switch out the downpipe. I was looking at the MBRP. I hear the 3" pipe can be put on without modification to the firewall and it will mate to my stock exhaust. Or is it worth the extra $300+ to go with the T-409 from turbo back? Can I fit the 3.5" or 4" downpipe without modifications? Can the existing hangers be used? What about the cat? Do I put it back on or does the T-409 come with a new one (I'm unsure)? Do I have to have a cat or is it left up to the state I register the truck in? I have 192k on the truck and only changed brakes and water pump since the warranty went out, is it too late to start with mods? I figure its cheaper than a new truck. Thanks for any advice.

We have sold a number of the MBRP system for the 1st generation PSD's now that they have been out for a while. The system is a turbo back that includes the down pipe which is 3 inches, the rest of the system is 4.0 inches. They are available in aluminized and 409 stainless. The systems comes with all the clams etc to do the full install and reuses the stock rubber hangers that are mounted on the truck from the factory. You will still need to flatten the seam weld at the firewall/floorbaord area to install the down pipe, there just isn't anyway around that no matter what down pipe or system you select to install, it's just a real tight area.
Call us at the office and we will be glad to help you with any questions etc.
On the cat, everyones suppose to have one. Vehicles have to meet Federal emission standards when built and by Federal law not modified (Clean air act). The EPA doesn't inspect individual vehicles to enforce the law, but will inspect fleet and state goverment vehicles. They usually will visit a repair facility of the above and inspect what is on the lot and being repaired. In other words they come to look for multiple violations where they can issue the biggest fines. Some states inspect for emissions, some don't.
The MBRP 409 system i had came with a cat delete pipe and used the factory hangers. Crew cab was the only system available and the pipe had to be cut for other models. At that time they had no stainless down pipe and I used another brand. 409 SS is not as good as 304 SS and mine had surface rust within 6 mo. The 409 is the only grade available for our year trucks. I guess MRBP doesn't feel the market is big enough for 304 SS, you wouldn't know it from reading this forum!
If your cat gets left off by the installer, save it. The day may come when it will be inspected and required and will cost you a couple of hundred to replace. In places where there are inspections, the center of the cat is broken out or gutted.
Don't think any trucks too old for improvements. Intake and exhaust will help it breathe better, but the amount of fuel and air it gets is controlled by the drivers foot. You already know that, by asking the ? These are good mods to make if you tow as well and will lower EGT temps that can shorten an engines life.
Bought mine without a cat. Near I can tell it was manufactured without a cat. Our 00 came through without a cat too?
