The delivery driver will attempt to obtain a signature from yourself, or a neighbour.

They will contact you to confirm they have your items and will give you the opportunity then to arrange a safe place, if required.

If they are unable to make delivery, a calling card will be left to inform you of the attempt. Couriers will generally make two attempts of delivery; after this time it will be your responsibility to collect the parcel from the local delivery depot near you.

We accept no responsibility for any costs involved when collecting parcels from couriers including any charges, duties or taxes.

Diabolus Black Stubby on Street RS
Wednesday, 7 July 2021  | 

What an amazing exhaust, not just for the price but in general. The build is fantastic, a real weight save from the original, the fit is fabulous and the sound, ooh that sound, What an exhaust note (actually several notes) deep rumble, spitting gurgles and roaring rasps. Why would you buy another brand when SP offers everything at such a great price.

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.
