Straight Pipe Question

[stroke this]

i have a 1995 f-250 powerstroke. it's chipped and lots of other mods, i just got it and i took the muffler off, but the cat is still there, i am going to take that out to but was wondering if it is a bad idea? it wont hurt the truck or anything will it? will it even make a difference in the noise? just wondering because i am new to diesels. Also, the chip it has causes it to shift at almost and sometimes more then 3000rpm's. i dont think this is good. it had a banks shift kit on it and we unhooked it thinking it would help but it didnt, can anyone tell me if this is normal with chips and maybe if my transmission will be ok? well thanks for helping me out!

If you run a strait pipe in stock diameter it can be a little "raspy" sounding, but if you do a 4" turbo back, it sounds good, a little turbo whine at idle, and really doesnt get loud untill your on the throttle hard!

well it has a 3 1/2 inch pipe, 3 inch downpipe

Ya, thats stock, it wont hurt anything, just sounds a little different.

You will notice that your turbo will spool much quicker.

3" dp is not stock and i think stock pipe is 3"

3.5" is stock diameter cat pipe... so YES, his is stock diameter

As far as the Banks "shift kit", do you mean a TransCommand? It will hold a gear for a while depending on load and throttle position. It was the single BEST thing I did for the trans on my old truck. Helped it last 9 years.

i did it, and it sounds great, can really hear that turbo too, and lots of black smoke!
