KMS exhaust systems are UK-made in-house with T304 stainless steel, which is mandrel bent, and then MIG/TIG welded.

This system is made in full 3-inch pipework, splitting in the rear in two 3". This will replace the factory system from your catalytic converter back.

* Your standard exhaust will require cutting to be removed, this should be carried out by a competent person.

* A Decat/Sportscat may bring on your MIL (Malfunction Indicator Lamp) unless you have Stage 2 software.

 

* Please Note: An exhaust system without a catalytic converter will NOT pass a UK emission test/roadside check and therefore it is not intended for road use.

Due to the popularity of these exhaust systems stock may fluctuate - this may be a 14-day lead time.

Smooth!
Color: Brown, Size: Mid Back, Color: Brown, Size: Mid Back
Good value and looks pretty good. Faux leather feels like Naugahyde. Should be durable since that's what boat seat are made of. Could use a bit more lumbar support, but overall quite comfortable. Wider than I expected (so it must be designed for us Americans.) Casters are fantastic. Far superior to traditional plastic casters. Because these are made of rubber, they are dead quiet and smoooooth rolling across the flooring. Took about 30 minutes to assemble. Lots of parts but the pictorial instructions were clear. I'd give it five stars, but I wish it had a bit more height adjustment. We'll see how it holds up, but so far I'm pretty pleased.

Very pleased with my purchase
Color: Brown, Size: Mid Back
Easy to put together - instructions are good - excellent quality and the chair is comfortable. Far from being flimsy it's a heavy chair which rolls perfectly as needed. You won't find that many good chairs (if any!) at this excellent price. As always the ultimate question is: would I buy it again? The answer is YES, definitively. Great purchase.

superb, worth 2x the pricez
Color: Brown, Size: High Back
While this may appear to be an average run of the mill copycat sort of generic office chair, it's actually very comfortable with perfect lumbar support. Looks great, and the leather (or leather equivalent) feels durable. This sucker will last me in my WFH setup for years I do not doubt. Save yourself a few hundred bucks getting this versus some "premium" office chair... I doubt you'll notice much if any difference.

22 year old gamer approved.
Color: Black, Size: Mid Back
So far so good!! I bought this chair for my gamer son, he sat the springs out of his last one, so this one making it this long has me very pleased. It was easy to put together, and the quality is pretty notable, especially the wheels, super smooth rolling. It was definitely worth what we paid for it, and he finds it very comfortable, providing plenty of back support, and a stable seat for hours of gaming.

The back of the chair is not supportive
Color: Brown, Size: Mid Back
Really nice casters that truly roll quietly. The faux leather is stitched well and sturdy. The only problem i have is that the back is not adjustable and gives 0 back support. The whole back of the chair is hollow inside so your lumbar gets no help. The seat is comfy but super wide like a lot of other reviews mentioned
