Pipe size between the two CAT's??
Does anyone know the pipe size of the pipe in between the two CAT's?? ((Truck listed below))
I can't get to it to get a good measure with a tape measure. I think its 3 inch??
Flowmaster makes a muffler with a single 3 inch inlet (Center) and 2.5 inch dual outlets. I think I would go with duals if I could use one of these instead of the "Y" pipe setup.......
thanks in advance for the replies...

[updated:LAST EDITED ON 18-Nov-02 AT 10:12 PM (EST)]Is a 3 inch into the muffler and 2.5 on out OK?
Or is it best to step it down to 2.5 after 1st CAT and on out with a SINGLE 2.5?
If A single is sufficient, It will save me some $$$$, and I like the sound of that!!!!!
I will search for your other post.
((ADDED))
I reread your other replies to the thread I started earlier.
I guess I was thinking of how to do duals WITHOUT the "Y" pipe.
I don't care for them.
Thanks for the replies..

The pipe between the cats was only 2.5 on my truck. It looked larger because it was all mangled up when the factory bent it, though.
FWIW, I am running a single 3" pipe with single inlet and outlet flowmaster. I havn't noticed any loss in low end, but I am also running headers.

thats odd, mine was 3" and im running a downpipe to 2.5". i asked about running 3" and everyone strongly was against it. i had him run a piece of 3" to the muffler and it did have a drop in power. maybe with headers it was more open. i dunno.
