Since I'm a newbie (one week), can I put the Big Honking Air Filter off my 95 on my 99, and will the removal of the muffler affect the electronics? I miss the sound of my 95 with a straight pipe. Also my 99 has the 4:10, which you can really tell on the highway, how many RPM's are to high to run down the interstate? I think my speedo's off some with the slightly larger tires and I don't want to turn the engine to much.
