whos in charge of the diesel site?

i was looking at the down pipe for the obs 7.3 on the site and it said that the firewall has to be modified.

what has to be modified and is it possible to have the instructions emailed to me?

it means you will have to take a hammer to your firewall to make some room for the DP....

call them up... ask for Bob....

All I did for mine was take a 2x4 and wedge it between the block and firewall and pry on it a couple good times and it fit fine

how much advantage will the down pipe give me if the cat is left on the truck?

[Matt P]

It wont be too huge of an advantage but it will help, I would get that cat off as soon as you can cuase its very restrictive

I did my downpipe with the cat on for a while and it was a lot better when I took it off

so thats why i was wantin to know.

i was not looking for a big difference. just wanting to help the flow of the exhaust and lower the egts.

Does your truck even have a Cat?

[Matt P]

youll hear the turbo a little more but not a whole lot but the flow will be better than that pancake of a downpipe thats on there now
