What would be overall HP?

What would be a good HP overall guess if I were to put a Magnaflow high flow cat on with my already installed flowmaster 80 series muffler? And then with a SLP CAI. Thanks

lets say probably 5 (enthusiastically) from exhaust, mabe 3-4 with CAI, and 1-2 (if any) with the cat. so around 11 at the wheels, but that sounds pretty high for just those... so ill say around 6-7hp at wheels. Once you get a few more mods, dyno it and figure out. but if you do get it dyno'd, you will probably cry, cause you never put as much to the ground as you think.

intake and exhaust are like beginner upgrades so that when you add more stuff in the future you will have it to support them, but by themselves they dont do much

indeed, my guess would be 140 to the wheels, if your looking for horsepower then its time to rip apart the engine, if its speed you want, then its time for the gear change
