Check out RW Carbon ... they seem to have the best for the price and they are in CA so it ships locally. Great customer service as well.

Interested in seeing how this looks... after a few brighter days over the weekend and giving the car a good wash, I think it could do with some Carbon!

Ok, fitted this today

To start it arrived in a few weeks from order and was very well packaged, it did not cost much in uk imports.

Quality looked great, however there is two blemishes in the corners which i think will cause a problem in the future its hard to tell, for now i have put some touch up lacquer into the crack.

It looks well made etc.

Fitting is a doddle, 3 hex bolts and a firm pull.

fitted it pics below, please read below for my thought too

It fits well all clips etc seem to be in the right locations, however if your a perfectionist (i am) it does not fit snug in the two corners and as such its easy to have it looks a bit miss fititing. I am going to play about with it to see if i can help the fitment but basically the two outer side clips dont seem to go home enough and as such you get a tad poor fitment from there. The gaps on picture 17 show this but its only obvious from this height

I think it looks good, I would say the standard pipes look a lot smaller with it.

Part of me thinks it would be better with one you paint but the carbon finish is ok. Depends on the color of your car mind.

At the moment im not convinced but this cost me about £200. Its a big difference.

Looks great - especially for the price.

I know what you mean about the Exhaust Tips looking a little smaller now... I think they would look better if polished up, and then they stand out against the Carbon?

Thanks for the pics.

thanks

its still ok and has grown on me, i want to say the fitting in the corners is a bit poor, there is a small gap and the eagle eyed will see it and realize, however 90% probably wont.

I managed to get a Turner rear exhaust box delete the other day so that should make the pipes bigger 100mm each hehe..

Hi Regy
I ordered the same as you which arrived yesterday but mine only has 2 fixing holes where there should be 3, plus they are not aligned with the car. Also the 2 popper holes on either side don't exist, but I don't know if these are needed?
Did you have to drill yours to make it fit?
Thanks

hi,

I just used the two fixings which worked out ok, the fit in the corners has put me off a bit more recently, i am talking with the supplier about. although they did align fine?

Had the car remaped by DMS last week and the rear box delete gets fitted tuesday

very good, initially i was a bit hmmm its not much different but it actually is you just need a hour or so in the car to realize, especially low down i find it much more drivable, you dont need to select a lower gear to get moving.

Indecently when you are giving it some the extra power does make a heck of a difference, you really need to hold onto the wheel, it feels like somthing out of fast and furious where the speed makes you really focused.

Also traction is not that bad in the dry, of corse you can spin up easy in MDM mode and you need to be a bit carful when exiting corners while on it as it will light up a bit quicker and lower down.

Sorry to go of topic, did you declare the tune to your insurance company?
I was thinking about getting mine tuned however I very much doubt my insurer will continue to insure me and if they did it would be way to expensive.
