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.

It’s a YES from me!
Color: B-brown
I absolutely love this purse. And I’m so heartbroken because something got spilled inside of it and it affects the functionality of the person on the inside and it makes me so sad but I still use it anyway because there’s one side I can use completely and half a side I can use on the other side lol. It is very good quality. The storage is A+. It is definitely a good value for the price. I was skeptical at first as we all are ordering a purse off Amazon, that is not real leather, but it’s supposed to be good quality. It didn’t really have much of a smell. I actually don’t use the strap provided since I seen that the straps could be interchangeable, I used my strap off my previous purse instead, and now I love it love it! 😍 I get compliments on it all the time!

Perfect size!
I love a good large hobo bag! This one has a great slouch to it and you can fit a ton in it! I've had everything from my iPad and a makeup bag plus yoga clothes and still had room for a water bottle too! The fabric is gorgeous and although I'm not always keen on logo-prints, I like that the bag's print is so understated and discreet.

Large, non zipping, sturdy, stylish
large cream MK purse I’m giving my thoughts on this purse that I got recently and here is what I liked. Size- This is a large purse. It has one large main compartment that is secured with a gold, snapping clasp. It doesn’t come apart unless you push both sides of this clasp. 1 pocket inside for my phone or whatever I need quick access to. 2 vertical outside pockets with working zipper. The pockets run the height of the purse and are narrow. I can get a skinny water bottle in there. Not Adjustable This comes with a short shoulder strap. The strap is not removable. There are two D-rings (H-ring) on each side that hold the strap so if I want I can add a long strap. Really though, this is not the kind of purse that would look good with a long strap. There is plenty of room to put the purse on your shoulder and it feels very secure. Look and feel It looks and feels like leather to me but it says PU which is not leather. I’m fine with that. It is firm in a sturdy strong way, having structure and can stand up on a table. The material is the kind you can wipe with a damp cloth. This purse is not going to get stained unless it’s something like ink that stains practically everything. Mine has monogram NK but if you don’t look real close, I think it looks a lot like a designer purse with the monogram m and k. Function I tend to change purses a lot so I keep things in smaller bags. For example, I have small bags for makeup, medical etc and they fit neatly in here. There is not a designated place for cards and cash so you’d need a wallet or you could put it in the inside pocket. I use a medium sized wallet. My iPhone 14 with case fits in the inside pocket and hasn’t fallen out yet. The 2 outside zipper pockets are large enough to hold my phone and my wallet, one on each side. I can’t think of anything I’d add or change right now. This is a very nice bag to carry everyday. The holding capacity is similar to the neverfull. I’m happy I got this and can recommend it to you. It’s nice looking, makes good use of space, and for me, was a good deal.

Quality is not there, I am very disappointed!
Color: Pink, Color: Pink
I am one of those very rare ladies that will wait until her previous purse is on its last leg before I buy a new one. That is when I decided I needed this one. Once I opened the package I noticed a very distinct odor, it was very obviously the purse and it was not a "new" smell it was very off-putting. The purse does not seem very durable as I noticed loose threads throughout the lining of the purse. I was also a little disappointed that this purse is so large but it only had one very large square pocket on the inside. The only reason I gave this more than one star is because of the two very nice pockets on the purse front. I appreciate what they were trying to do, I do not think they were quite up to par on the quality, I would not recommend this item.
