I have a trailblazer LS4 TB (3.5") and and injen intake (2.5")

was wondering what coupler u guys are using as nobody has the one i need (not even home depot)

tried several places so any help would be nice

thanks

 

If you figure something out let me know i'm also curious

 

anyone done this mod that can offer some insight
\

 

i believe rebel sells one, it was only a 3" coupler and they had to hat it up to strech it over the tb

 

hosetechniques.com
3.25 to 2.5 reduction coupler.

 

just checked out hose techniques (again) and cant find it... do you have a part number or link on thier site

also do you know if thats considered a 90 or a 45?

 

i would say 90. maybe 90.5
