Just wondering if anyone has any experiences with the Gibson Supertruck exhaust. I love the looks, but I'm a little concerned that it might be too loud. Also, just wondering how exactly it will impact my performance of my 99 4.6L.

Thanks,
Joey

 

I have the Gibson Supertruck exhaust on my 1997 Supercab 4.6L... its not crazy loud but it definitely has a nice rumble. I think it sounds pretty good. If you order it I would suggest getting the stainless steel version, its worth the extra money.

not to loud at all..and you probably wont feel much performance gains with it

 

Oh, and performance wise, it made a decent increase in power, not huge though. I would probably notice it more if I didn't have big heavy tires on my NPI 4.6.

 

Well, I'm mostly interested in how loud it is when cruising around 65-75MPH. I just sold my 93 Lightning, and the exhaust that I had on it was extremely loud when cruising at these speeds. I don't mind it roaring when I get down on it, but would prefer it not to be so loud when driving normal. I have to admit that its the appearance that I love, and also the fact that it bolts on using the stock hangers..
Performance-wise, I know that I would be loosing alot of back-pressure, and I'm not sure how that really impacts low end performance, as well as towing-peformance. I need someone to school me on this...

Thanks
