So I didn't like the halfcab conversion I did because it wasn't reallly a Jimmy anymore and I messed the back seat. I don't want to put carpet back in it because I might go with a soft top and the fact that I don't have the carpet anymore. If the soft top works out I don't want to have to worry about water issues in the rear of the truck. So I thought about Herculining it and want to know if the Herculiner reduces the sound levels any. From what little driving I have done, I'm pretty sure the noise levels are going to be unbearable....40 series Deltaflow, 3" exhuast and no cat. Has anybody noticed any significant decrease in sound levels after applying Herculiner? I have searched and found one post stating it was still loud with it in there. I'm pretty sure the hardtop acts a huge echo chamber so maybe the soft top won't act the same?
