Just want to make a statement, exhaust

[TampaDieselFX4]

I went with a 4" turbo back Magnaflow kit. Came witht he parts/hardware to run Cat or no cat. and can be switched out if need be... ie warranty. I kept my stock downpipe, Cat, and pipe after the cat incase "need be" situtations. So the stock tail pipe section is trashed.

I started by removing the stock muffler, and yes it was a good improvement over stock.

Since the innards of the cat are made of somethign brittle, would it be possible to bust out the innards of the cat?

yep.... ....but if you have to go for an emission test in the future, you will need the cat functional....always best to use a test pipe

I did buy the cat delete pipe from diesel performance, The neck of the pipe that bolts to the down pipe is choked down to 2.5" , Wasted money.
Why use this pipe? Maby someone else makes a test pipe that doesnt choke the flow?

dennis -

when you consider that 'choke' down is the same as the FACTORY
cat fitting, plus the catalysis inside the factory cat, youll STILL
be flowing more & restricting less heat.

if you dont like the "choke" down then you could always cut the
flange off the down pipe and clamp a pipe on...but then you wouldnt
be able to bolt the cat back on, if you ever needed.

I also put a chrome tip on the end of the exhaust.
Thanks, Shane

I'll give you bonus points for the chrome tip, heres +10

I agree with not cutting or gutting the factory cat. I got my test pipe from the dealer. Not the dealer I bought the truck from but another. I have had my truck in for warranty work several occasions and never put the cat back on. I have one of the good dealers I guess. Even the dealer I got the cat delete pipe would work on my truck also without a problem. Helps that I stop often and visit and have good relations with the service dept. Plus small towns help!

I second that. Having a good, friendly relationship with the dealer is a good thing.

i recently recieved my yearly examine results from my kitty's vet
diagnosis is still restricted breathing
prognosis is keep her off until the breathing tube can be cleared of restrictions

egts run 200-300 lower
towing egts reflect the same drop of egts

I have a turbo back off road MBRP kit that does not have a bolt on flange for the test pipe. It is 4" all the way back no bottleneck and when i need to put the cat back in I just replace the test pipe with the cat with expanders and reducers on either end. Looked a bit funny/ choppy (about 6 ubolts) but it worked for the dealer.
