We have designed our exhaust manifolds to maximize the exhaust air flow to reduce turbo lag time and cool exhaust temperatures. In the design of the manifold each port is analyzed and tested to provide a balanced flow to the turbocharger. Big Boss Exhaust Manifolds produce, on average, a 20% air flow increase over a stock manifold, cooling exhaust temperatures by 75-100 degrees. PDI manifolds are a big part in maintaining the best exhaust pressure to boost pressure ratios which will provide potential for increased fuel economy.

At PDI, we use only the best material for our products. We use a superior grade of High Silicon with Molybdenum Ductile Iron (HSMD) that eliminates weak points such as warping, cracking, and center divider failure from heat erosion. This material, combined with a redesign of the mounting surfaces, eliminates common failures due to a fatigued manifold.

Fantastic purchase completely happy
Color: Beige (4 Packs)
Awesome soap bag the construction is very sturdy and allows for good lathering and I would definitely purchase them again. It also helps with exfoliating so you’re getting two birds with one stone.

Great product for the price, would buy again!
Color: Beige (4 Packs)
Great bags. There is a ball to pull the top right but it slides back open so I just tied a knot in it but idk how I'll get it out to put more soap in. Otherwise a great product! Glad I bought them! Color is neutral, lather is good, very durable, easy to use, could be a little rougher (in my opinion) it's on the soft side, functions great besides top coming open, very durable!

Small to big soaps, not exfoliating
Color: Beige (4 Packs)
My soaps haven’t slipped out. I use dove bars and smaller round soap bars in them and I haven’t had any issues. They leave a room around my dove soap bars. I’m glad I can bar small to large soaps in this bag. I haven’t need to tie a knot on the end like I often need to do. They feel like a soft scrub on my body, not exfoliating. I enjoy my tan colors.

Not the best, but good enough
Color: Beige (4 Packs)
It is useful since it keeps the soap in and works well. The problem is that when the soap dries some parts of the bag become stiff and scratches your skin. It gave me a rash.
