are you still stock heads??
and what kind of rpm are you turning the MS4?
also how does it pull at all rpm's?
im wanting to get that cam or the trex so thats y i am asking u?
but for the exaust maybe you should go with some 3"true duals they will def let that cam breathe.

Duals would really do you good. I also have the Ms4, I'm running open headers though. lol We run true duals on our TRex cammed car, and I really just don't think any exhaust comes close to duals...twister mufflers, or bullets if you like REALLY loud.

I haven't put mine on the dyno to see actual numbers, but I can tell you it pulls hards all the way up to about 7k where I've got it set to shift. It is a MONSTER.

so how many miles do you have on your car?? and is the bottom end still stock?

monicaz28

It is a stock bottom end. No reason to change that at all unless I was spraying a lot, which I'm not....yet.
This motor has probably 5-7k miles on it now if that's what you're asking.

How are people getting 10 more RWHP over a cut-out with true duals (I am assuming an X-pipe?)? Does the "scavenging effect" really do that much over open headers? I have true duals with long-tubes on my SS and plan on getting either the MS3 or the G5X3 pretty soon.

i donno what causes it, but the case in point has an x pipe with a hotcam

spazzyfry123

iTrader: (4)

Just curious, but did he run the hotcam with open cutouts and then the hotcam with the X-pipe (with no other changes to the car besides X-pipe/cut-out)?

chris93266

iTrader: (5)

yes...

magnaflow catback with open cutout to true duals with x

same cam

I have the Mufflex 4" single exit exhuat on my camaro. Many people think that is too mig for our cars but it has just about the same surface area as a dual 3" with the duals getting just a little more area, aka within a 1.5 square inches.

4" system has 12.6 sq in and the dual 3" has 14.1 sq in.

The muffler on my car is a flowmaster.
