The Gruppe M intake showed peak gains of 6.6 hp and 3 lb-ft with max gains of 10.5whp and 7.1 lb-ft. With the exhaust, additional gains were 3 hp and 2 lb-ft with max gains of 4.3 whp and 3.6 lb-ft.
Better than the aFe stuff which showed no gains but is it worth it? The Gruppe M CF intakes are $3,162.40 and the titanium exhaust is $5,616.80.
In contrast, the RPI scoops with BMC filters, at $184, have seen from 10-18whp and their GTM exhaust, which sells for $2,750, have proven gains of 28whp and 35 lb-ft.
