Good evening! I just recently had Crower stage 2 cams installed in my 08 Shelby. I know, in the 4V motors, the stage 2 cams aren't going to hit like a B or E cam in an old push rod fox body engine. I didn't want to go any larger because I felt like the stage 2 fit my setup and wants. My concern is you can't even tell the cams are in the car unless you hold your head right down at the muffler. I have heard 2 other Shelby's with the exact same cams in them and they sounded great. My idle is set the same as one of them I know. The difference is they had full 3" exhaust and I ended up going with 2.5" to try to keep it from dragging as much as possible. One of the other cars has the Corsa Ultimate Touring and one Borla Atak. I am running the Ford Racing SVT-1 mufflers. I do have 1 7/8 long tubes which is what they both have as well. All cars have off road x pipes. Do you guys think my exhaust is keeping the cams from being heard? Is it possible I just need to change the axle back? I have a mail order temp tune from VMP until I can get to the dyno, could that be part of it? I know the SVT-1 is not a loud muffler but I would kind of like to stay with the Ford Racing and thought about going with the round Ford Racing mufflers which I think are Borla? and a little louder than the svt-1. I guess I am just looking for opinions/answers as to why I am unable to hear the cams. Thanks for any input here.
