Thursday, 14 May 2020  | 

Ordered at lunchtime on my doorstep 10am next day! less than 24hr delivery!! Emails sent through whole process, great communications.
Top quality engineering, i bought from other brands in past, after reading various reviews decided to chance this company, so glad i did, can't fault the product, well made and lovely finish, i will not shop anywhere else now, also bought Evotech products from this guys using the loyalty scheme saved a few quid so another bonus!
Would highly recommend shopping here, great company to deal with, will be buying parts here again for my other bikes.....

Very impressed with both service and quality from SP Engineering. The exhaust is stunning and very well made as are the clamps and link pipe. As advertised if was delivered next day and very well packed. Nice little touch to receive a free neck tube.
Well done SP Engineering!

Diabolous XLS Carbon for TST 765R
Wednesday, 21 August 2019  | 

Shipment incredibly fast, the exhaust is astonishing well made and it sounds amazing. No power loss or fuel issues so far, plug and play and huge weight saving.

Fits perfectly on the TST 765, I couldn't be happier with my new exhaust.

Acabo de comprar e instalar el Diabolus XLS a mi Triumph Street Triple 660. Envío rápido, facilidad de montaje y el escape se ve de mucha calidad. El sonido es espectacular. Sin duda lo recomiendo y de hecho varios amigos van a montarlo en sus motos.

I just bought and installed the Diabolus XLS to my Triumph Street Triple 660. Fast shipping, ease of mounting and the exhaust looks great. The sound is spectacular. I definitely recommend it and in fact several friends are going to ride it on their motorcycles.

A Superb Product
Thursday, 18 July 2019  | 

This is the second can I have purchased from SP Engineering for Triumph's. The quality of this product is exceptional. It is beautifully made, comes with all the fixtures needed (and they are high quality too) was delivered promptly and packaged well. I cannot believe I have such an excellent quality can at the price... well done SP.

Thanks heaps to all the team at sp engineering.
Ordered my slip on a week ago and it rolled up today in Aus, so I fitted it tonight.
Couldn’t be any happier with the way it sounds and it also looks awesome.
