    i have twin vs racing 7875s which are a 2.5" outlet. i plan to mount them in front of bed and mount a2w behind right rear tire. my question is will going from dual 2.5" inch outlets and merging to a single 4" hurt flow or effect performance? im running a type 12 a2w which is a 4" in and out. my other option is to adapt each turbo to 3" and then merge them.

    attached a pic of what im thinking about

    Iā€™d say leave the 2.5ā€ tubing and merge it to 4ā€ a bit closer to the intercooler than the picture
