Down Pipe/cat needed

[AMcCormick]

I need a 4. 5" down pipe and cat to fit an 05', any ideas?

I don't know of any 4-1/2" down pipes. I have a 4" dp for a 2003-4 to replace the original 3. 5" pipe. I also have a cat, good but cut out so the ends are only a few inches long (either weld to something, use strap connectors, etc. )

Andy,
Why do you want a cat? Is this for your 03? If so then you need to understand that your truck should not have had one unless it was a California vehicle, and I am not even sure it had one then.
I just took my stock system off and all it had was a muffler. So I went with a 4" system and a straight Donaldson muffler and am very happy. and this is on an 03 QC with almost the same equipment you have.

To elaborate I am selling the truck in sig and buying a 05 quad cab that has DDP 90s, BD Special B turbo and a 5" turbo back exhaust with a built GB billet shafts transmission less than 10k miles. I am also in the SF bay area so I am going to have to pass inspection. The truck is coming with the stock turbo but not the rest of the exhaust. I believe that the 04. 5 up trucks have a 4. 5" down pipe?

AFAIK that would 4" not 4. 5". Just get the stock DP.

Ya'll better keep your CAT's.

My mistake, for some reason I thought it was 3. 5" on the 03-04 and 4. 5" on the 04. 5-up.
Joseph Donnelly I've sent a pm.
