well i have both welded on lower pipes coming out to the intercooler (cold side) , After more research and looking at how gtm setup is they install them one the cold side and one on the hot side as you see in pic i attached, which to me is the best, it takes out the extra unwanted air (pressure) in both pipes. i know to each his own in this but i am looking for performance and sound as well, so having them next to the throttle body( gtr set up) will give me the same performance and sound i have now which i am trying to make it
better. this will confuse us abit
