 Trustindex verifies that the original source of the review is Google. Speedy service, highly competent in what they do and all round great communication. Rang James after going off these reviews regarding his work. Essentially, rang in the morning needing a quote to get my exhaust repaired. James said to send him some pictures of the issue and in my case he was able to quote over text after reviewing. By the end of the day, I had my exhaust repaired and car was back on the road. Bearing in mind I dropped it off at lunch time and it was done by 5pm. Smashed it - thank you.

 Trustindex verifies that the original source of the review is Google. This company has provided a 1st class job! I had my exhaust repaired as a final measure, due to it being old and no longer listed as a spare part. Well pleased that I made that decision, as it saved me hundreds of pounds and the work is so professional that you'd never know no the difference! Thanks again for a great service.  I'd definitely recommend JCCustomz to anyone needing a bespoke and fairly priced service. Excellent experience.

 Trustindex verifies that the original source of the review is Google. My E36 325i Convertible has a wicked cat-back system, thanks to James; he done exactly what I wanted for my custom exhaust. James is friendly, polite and a professional chap. I highly recommend JC Customz.

 Trustindex verifies that the original source of the review is Google. Very professional, booked me in and had my exhaust built with less than a 1 day turnaround. My car is a 2008 E82 135i (N54) and it has now been converted into a single piece all the way back.
