A lot of MKI N/A's in good condition are lucky to register above 100WHP on the dyno. Most are in the high 80's to low 90's. Torque is even lower. If your car were stock and in PERFECT condition, you still wouldn't be making 120WHP. As LordNikon said they put down 112HP at the CRANK stock, to the wheels even less.

In your first post you mentioned a bunch of upgrades you wanted to do. I hope you realize doing all of that won't make your car significantly faster. Most of it is just maintenance.

Upgrading your muffler does nada for you. If it's too much larger than stock it will actually hurt performance. Getting a FULL exhaust from the headers back might help a tad, but it's not going to give you 30WHP or anything. Maybe 10? If you build up your engine you benefit more from exhaust, stock power doesn't need much more if anything.
