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.

Great suit!
Color: Black, Size: Small
Great suit! Suit is well made for the price. Very comfortable, nice material and could be worn for any occasion no matter the time of year. We ordered according to the size chart and fit great! Would be easy to do a little tailoring if needed tho. Came in quick and is exactly what we needed. Will be ordering other colors for the future!

Just an unbelievable purchase and strongly recommend
Color: Black, Size: Medium
Unbelievable! One of the BEST purchases I made. Fits perfectly, wasn’t wrinkled at all. In fact, I don’t need to take it to the cleaners to be pressed. Class all the way. Well made, elegant, fabric was perfect as it was not too thin. Compared to tuxedos in the store and this was exactly the same. Only difference is this suit was $150 less!

Good. Decent quality.
Color: Black, Size: Small
The quality is good, especially for the price. I didn’t like that the wrist buttons were non functional. We bought cuffs that he couldn’t use. It looks nice. The size is a little big for my son, but that was kind of expected. I was hoping we would get lucky and that wouldn’t be the case but I couldn’t find any suites in a smaller size that would arrive on time. He is 5’7, 120-125 pounds. It was mostly in the shoulders that it looks big. He is thin. The arm length fit him but he does have long arms. The pants fit with a little looseness. His jeans size at American eagle is 28/36, but he can fit slightly bigger with a belt. The pants were good but the vest and jacket were a little big. They’re just slightly long and jacket is big in the shoulders. We got a size small.

QUALITY AND COMPORTABLE FITTING IN LOWER PRICE...
Color: Navy, Size: Large
WOW! this suit really true to its sizes description... I ordered in a different company before this, but I have to return it TWICE because of wrong size fittings... Finally, this beautifully tailored suit timely arrived before my son's wedding reception, and we are ready to celebrate!!! Thank you and might order some different colors in the future... I wonder if they can make the pants in higher waist and straight cut or wider for the legs in the future as an option... Just a thought since slim fit pants are slowly outdating...
