my current build im doing im using a garret 91mm with a 5" dp flange so im wanting to go ahead and do 5" all the way back it looks like i can do it but im gonna have to cut my transmission ear off and its gonna be tight.

i also could use my old 4" dp and have bout 20" of 5" before it gets to the 4" but if i can i wanna keep from doing that

i was gonna see if anyone else has a 5" dp if they can give me some pics to get ideas from and tips would help. thanks

I wouldnt worry about a 5" dp unless you have a 400ci or larger engine. Plenty of 6.0 guys make good power on 3.5" downpipes, so a 4" would more than suffice for most setups.

 

Exactly what i was gonna say, 5" is for big power no need for it on smalle setup unless you just want it to look cool i suppose

 

Hood stack, problem solved

But if I had a track only truck Id consider doing that but I dont know what your truck is

 

well thats the thing my truck is mostly strip but i do take it out on some weekends but if all works out well im gonna drive in more on the street.

setup is a ls3 headed 404 stroker vic jr intake th400 transbraked
on 15 psi hoping to get 800rwhp

 

making hotside im gonna finish welding this week and hopefully be working on downpipe this coming weekend that way i can order some stuff if i need to 5" v band ect.
