This is more of a question regarding the neccessarity of this item. Obviously its better to have better air flow with an aftermarket elbow, but how neccessary is it to have? My whole exhaust is done to my liking and im about ready to invest in a good boost controller, should I get a new elbow first? Just looking at the thing, it looks so thrashed over the years nevermind for better flow, just replacing it for the reason its been heated up so many countless times in its 17 year life. Any concequences for moving forward and NOT getting rid of the stock elbow?
