I know there are companies that make full 5inch exhaust and full 4inch, but i was looking for a full 5inch turbo back and then into stacks??? But also wondering if its worth getting the 5 or should i just go 4 then to dual 5inch stacks???

---AutoMerged DoublePost---

just cause MBRP makes a 4inch turbo back to dual 5inch stacks. Would that kit be sufficient enough??

 

i have 4'' in to 5'' side pipe but i just took down the stacks.. 4 in to 5 is good enough my truck is a 93 idi 7.3 srw 4 door 5 spd stick 2 wd

 

4" is more then enough, but IMO get 6" or 7" stacks.

 

Dual 4" out the sides with 6" SS Tips

 

i scored a set of 5 inch mitercut stacks for rebuilding a guys engine. just not sure if i want to install them.

 

i'm partial to 4 inch down pipe into a 5 inch stack or 6 inch but i'm still rocking passenger side exit behind the tire cuz i love echoing off wall,houses,guard rails, or people if there in the way hahaha i know i'm dick

 

I would go 4" exhaust to 4-6" stacks. If I can help let me know.

 

I was thinking of going with a 4inch down pipe. Then i'll prob go with the stacks. If i need anything i'll maybe give u a shout Tyler, thanks.

 

Most common set ups are 4" to the y-pipe. From that point it makes the transition to the stacks. Our kits are 4" under the bed, with a 5" y-pipe. The transition is at the bottom of the y-pipe, so when you look in the truck bed you see nothing but 5" plumbing. However if you look under the truck you will see nothing but 4" exhaust.

 

Thats wat i was looking for. But i'm not sure if i can bring myself to cut a hole in my new boxliner!! I'm not sure what i'll do!!
