The Sound

Starting at the manifolds, replacing the stock cats for our 100 cell, or long tube catless Inconel headers opens up the sound significantly. The gases are then passed through one of 2 channels. On valve closed, the gases pass through our harmonically tuned, and internally ceramic insulated wing silencers to remove unwanted drone during highway cruising, and into the center muffler, and finally our trademark 1D CLR x pipe, this setup keeps the car very civilised when you want it to be.
On valve open The wing and center silencers are completely bypassed, allowing the gasses to pass freely through the exhaust system. The geometry of the Kline 1D CLR X pipe raises the pitch of the exhaust significantly into a raucous, yet beautiful, incindiary scream, without causing any restriction to the gas transit. The material Inconel 625 also has a unique sound, further enhancing the natural charachteristic sound of the kline system. The sidewall is very thin, and resonates to produce an even higher pitched scream at high revs.

Performance

The largest performance gain comes from replacing the catalysts in the stock headers. The Kline headers and full system are designed to work in conjunction with eachother for optimum performance and sound. The Kline system and headers are available in 2 options, 100 cpsi catalysts producing a largest gain of 18 hp and 27nm, or decat long tube headers producing a largest gain of 24hp and 35nm.

Lightweight, Breathable Polo Perfect for Hot Weather Gol
Color: Blue/White Square, Size: Medium, Color: Blue/White Square, Size: Medium
For reference, I’m 5'10" and 170 lbs and ordered a size Medium, which fits true to size. The shirt is probably designed with tucking in mind, as it runs a little longer than some casual polos. That said, it still looks perfectly fine worn untucked if that’s your preference. The mesh material is lightweight and very breathable, which makes it ideal for hot Southern California golf days. It does a great job keeping you cool even when you’re out on the course for several hours. Another thing I like is the amount of stretch in the fabric. It allows plenty of freedom during the golf swing without feeling tight or restrictive, while still maintaining a clean fit that doesn’t look baggy. The pattern is nicely done, with subtle colors that look good without being overly loud. It has just enough style to stand out a bit without feeling flashy. The collar holds its shape well, which helps the shirt look a little more polished. It’s stiff enough to stay looking sharp and it washes well without losing its structure. Overall, this is a comfortable, lightweight polo that performs well in warm weather and looks good on and off the course. A solid choice if you’re looking for a breathable golf shirt with a good fit and plenty of stretch.

Excellent Suit for the Money. Great, rich details.
Size: X-Large, Color: Black
This is a stunning piece of clothing. The material for the vests and pants are so luxurious and make it look like you spent a lot of money. Great versatility and thick material of great quality. The material is made of a rich fabric that feels subtle and gentle, but with the patterns showing well. It fits well and allows for movement. Whether you are looking for a wedding suit, or something to wear to a gala or bow-tie event, this is it.

Buy the suit. Be sure to measure!
Size: Large, Color: Red, Size: Large, Color: Red
Suit looks better than the photo in person. The suit is also made well. Great fabric and pattern! My son is 6'1 and weighs around 135-140 pounds. I ordered a size large for him so the pants would be long enough. The pants were a little big but it was nothing a belt could not fix. The jacket and vest fit well too. The item also arrived on time. ***Suit runs small BUT if you take out time to do the measurements you will get the correct size.***
