Need to replace the clutch on my truck. Wanted a heavier duty, wasn’t sure which one to get. I called spoke with a sales rep. Told me which one to purchase. I had to use affirm as payment and was only able to do it on line. I hit the clutch in a few days. Had a shop install. Truck was almost un driveable, had to shut off to put in reverse, had to force in gear. Horriable. I called Valair they said have to talk to sinister. I spoke with sales manager he informed me I was told to buy the wrong clutch. So I said that’s ok I’ll send it back just want the right clutch. He said because I purchased it on the web site and the description was there there’s was nothing he can do. So I’m out $1100 . I guess I should have known . But my mistake I was understanding that they would know the product they were selling and would stand behind their mistake. I’m sure they have good products. But my experience they will not stand behind it if their is a issue.... If you want to purchase maybe best to call not purchase on line...

The oil filtration kit was perfect. These guys have spent the time to perfect this kit. Easy to install and was a great compliment to the coolant filter I already have.

I own a 1997 f350 Powerstroke 7.3l and I ordered the MBRP as the first step in pumping the truck up to somewhere around 500 hp, the stock exhaust came out easy, and the MBRP went in even easier, if you follow the directions and bend your firewall correctly the downpipes will go in easiest, my only trouble was cutting the mid section of the pipe to length as I had to mach up and tighten everything down to get a measurement, then take it apart and see if it fit which I did 3 times as I was scared of cutting too much pipe off, I WISH MBRP would list some measurements for different truck lengths so that you would have a frame of reference how long to cut your pipe, I have had it in for about a week now and have had absolutely no issues whatsoever.
