ok folkes,
I have a 4.2 V-6, what should I go with???
I am more interested in low end pull, than sound.

 

I would tend to lean towards Gibson. I don't know what hp figures Borla claims for their truck exhaust, but I read an article in a performance Harley magazine where they did a direct comparison of exhaust systems using the stock system as a base. The Borla system actually made *less* power on the dyno than the stock system! That's bad. I don't care about sounding cool either. More ponies is what matters! I haven't had my truck on a dyno, but judging by feel (which is limited at best) I don't think the Gibson system makes any more power than stock below 2500 rpm. It feels a little stouter above that though.
