Pondering a turbo

[saburai]

Thanks! Other than the Diamond eye, do you know if there are any good, relatively bolt on downpipe or turbo back systems available?

 

[FORDF250HDXLT]

detailed exhaust part list.in order of flow:

banks down pipe.
banks intermediate pipe (just front section.) this connects the odd sized banks dp to a 3" pipe and bends down to be parallel with the trucks underside.came with kit this time! saved me some coin.nice bonus.
3" to 3.5" adapter - walker 41981
a stick of 3.5" pipe
"big truck muffler" - walker 21470
short section of 3.5" pipe (just enough to hook muffler to adapter below)
3.5 to 4" adapter - summit 652269
4" tail pipe - dynomax 54387
then some clamps and hangers of course.

1993 Ford F-Super Duty XLT - "Log Truck" (new to me truck-pic heavy)

Double post.

Many thanks! I'm assuming banks still sells the intermediate pipe. Would you happen to have the part number? Alternatively, I can contact banks. Thanks again, looks like a plan...

Thanks! I didn't see the turbo back kit... Also, what do you suggest for a muffler?

Why do you want a turbo back kit? Thought you were using the banks down pipe.

Based on what Thewespaul said, I would get the turbo back system and cut a bit off as opposed to having to by and fabricate. Let me know what you think.

This is what I would buy, you would probably have to add a bit of 4" to meet with the end of the downpipe or you can spend the extra money and get turbo back and just not use it all

My bad, when I made my post the 3 previous weren't there for me but yours... lol. If you want a muffler I believe diamond eye sells a kit with one as well.

However the one you linked is a cat back system, not dp or even turbo back.

If you buy the Banks downpipe you will need like a 1 foot long section with about a 30 degree bend in it to run a downpipe back system, 3 inch slips right over the end of it I believe l

Thanks! So if I go with the banks DP and the Diamond eye 4" turbo back system, I'd need a piece of 3" to slip over the banks DP and then a 3"to 4" adapter to mate to what's left of the Diamond eye DP. This sound about right? My goal is to be able to put this together as a slip fit, just cutting the downpipes and welding the ******* downpipe up later if necessary.

The banks downpipe, at least on my banks wastegated kit, is 2.75" or so. 3" fits over it with about 1/4" of clearance - it's not a slip fit by any means, but the gap is weldable. You might try getting a tailpipe expander and just expanding it untill it is a slip fit.

Thanks for the good information!

The pipe I slid over mine was 3 inch OD so the pipe was smaller then 3 inch inside and the exit of the banks 2-3/4 inside diameter, small gap left weldable yes I used a 3in-3od strap clamp over the connection and have 99% sealed I belive no noticeable leak but I can't garrentee no leaks because I haven't really looked at it much since install
