What was you trying to say project lol..

I currently use the evo 5 grs front mount and can't fault it apart from you will experience more lag but with harder punch once on boost
. The front mount rs500 that airtec do is tempting but I'd prefers a grs with same design and I would expect better flow than airtec but you would need plenty of cash. Sorted is the cheaper option that I see most people go for.
