I had a FlowMaster installed on my H3 as well. I took it to a muffler local shop and they did it for $120.00. The FlowMaster replaced the stock monster muffler and was attached in the same location. The single short tailpipe was cut at an angle to fit under the bumper. Looks good. The resister was left in place. I was adviced the sound would be somewhat louder if it was removed. I might get brave and replace it with a streight pipe and see what I get sometime. I'll save the resiste,r just in case it gets to be to much for me, or the wife complains. So far I'll just keep the radio on. LOL
I did notice better pick up and a little increase in sound. More like mad hornets, but not to loud to bother anyone. So far my wife has not complained.
