im running the hx-40 downpipe with the hx35 to hx40 adapter on my turbo to fit the downpipe. im wanting to run 5in exhaust back and was wondering if the kits come with a 5in downpipe like the hx40 DP i have. im asking because i dont have the stock exhaust elbow anymore since i got the downpipe. if not i guess i can buy a 4" to 5" adapter, and then run 5 inch back. i was really wanting to do 5in turbo back tho

 

anyone know?

 

i ordered a 5" for my truck. i have twins so i had to use a custom DP, but the kits come with a 4" DP that bolts to the HX35 adapter, not the HX40.

 

ok thanks, looks like ill be getting a 4" to 5" adapter

 

You should be fine with what you have, most of those systems use the 4 inch downpipe and then expand to 5 inch, there isn't a whole lot of room in there for that big of a downpipe.
