Aftermarket Intake/Exhaust Manifold

[Mr Hagg]

I can say this I have installed it on several guys trucks that was very conservative drivers and they too was looking for a mpg gain as advertised. I agree it did look good however all was ot happy to know what they spent and no MPG gain. The only thing we did notice was exhaust temps was down maybe 25 to 50 degrees and we had to remap turbo some as boost was alittle to high it gained 4 lbs.... Then in about 2 years or less the exhaust manifold turns and will have some rust look to it... So at the end of the day was a short time high so to speak and personally do not think its worth the money....Thats is just my 2 cents....
