Does any one sell a 5" down pipe? Or will one even fit on a 97psd, bc all I'm finding are 3"

i dont think a 5" dp is made by anyone or would even fit. a 3" dp is pretty much standard use on an obs

[bkhall]

3" is bad enough, can't imagine trying to fit a 5"

3 inch is all your gonna need, 5 inch will need MAJOR firewall constrruction, 4 inch will need work too

So 3" down pipe to a 5" all the way back

3" dp to 5" all the way back is what i got and love it and a 3" dp barely fits i couldnt imagine a 5"

3" DP to 5" exhaust is the way to go.
To be honest there isn't a reason to go larger than 3". Unless you are putting down obscene amounts of power and flowing huge amounts of the air, 3" is plenty. You'd have to be running some oversized headers/manifold and up pipe then as well.

Ok so now that I plan on going with a 3" dp. Where can I get a cheap mbrp or silverline exhaust been looking all day and can find 4" all day

3 inch is kinda on the small side considering the size of the motor, I know that is all there is for an obs but you figure it is a 7.3 motor, I have the same size exhaust on my 2.3 four cylinder mustang. Just saying, I'm not talking bad as I have a tymar downpipe and it makes a big difference.
