Gains = probably slight gains.

Problems = its being sold by XSpower (known as Xtra sh!t power to most jap owners that have bought their tatty shiny stainless rubish)

Fitment problems with XSpower parts are well known, they are all cheap, poor quality chinese imports, I had failed XSpower intercoolers, turbos from them that lasted less time than they took to fit, rubbish customer service etc.... do some searches on their parts, you wuill seee what I mean!

A decat isn't a bad idea if you are going to get one that you can easily swap with a cat come MOT time.

Mine cost a little more than that. :shocked:

Are there any others that are worth buying? There's 4 or 5 different ones on eBay or and I better off just going the whole way and putting a milltek decat on?
