I'm new to the forum, about a week now, and from what I have read the Tymar DIY is a cheap and easy instal. So I tried it, I bought the filter on-line for 24 bucks and found a piece of 4 inch exaust for 22 bucks at Fleet supply localy and I had a local muffler shop cut the pipe for me (Freebie) The install took 20 to 30 min tops and I was back on the road. I still need to fabricate a bracket to hold the filter but for now its zip tied in place. My truck (96 F250 crew, short bed) runs smoother and the turbo whistle is now noticable. I didn't think I gained any power at first so I hooked up my camper (around 8,000lbs bumper tow) and went for a drive. WOW! did that made a differance, my truck must have realy starving for air. At city speeds the truck has no problem keeping up with traffic and once I get to hwy speeds the camper is not noticable, if you don't count the fact that I can't see around it. Today I drove my hour commute to work. Once I got in traffic I could tell a difference. The truck is much more responsive. I will know if there is any MPG improvement by the end of next week.
I feel the need to warn any other newbies Turbo Whisle is an addicting sound and your right foot [I]will[I] gain weight after the install. I'm hoping these are temporary ailments or I will not gain any MPG improvement.
Thanks for all the helpfull tips on this forum I think I will tackle a turbo back exaust next.
