What a great, honest review. Well done! I’ve watched several videos on these X pipes (for my Speed Twin) and still haven’t been able to decide whether to go ahead. Your honest and straightforward review was very refreshing and has definitely made my mind up for me. I’ll stick with stock. Thank you👍😊

Thanks for pointing out the interior weld slag. I have a Tec x pipe here, it is much the same. The slag forms when the fabricator doesn't bother back purging the pipe with argon. It's fairly easy to do the back purge, but it would add a couple of minutes to the welding time.
I looked at a video for a Motone x pipe install. The reviewer talked a lot about " marine grade stainless used by Motone" and generally suggested that the Motone was head and shoulders above the other makers.
When he put the camera inside you could see the same weld slag  bumps and lumps hanging into the flow as with your & my Tec x pipes. He made no mention of the slag, just kept raving about the quality.
I think Meerkat is the only one properly welded.

So refreshing to get honest and unbiased reviews instead of the usual shilling of gear from other bike YouTubers. Thanks Toni!

Hi Toni, thank you for this great review. Have fun, drive safe.

100% super appreciate the honest and thorough review, cheers!

Great honest review as I have been thinking about doing this. The point about the coked welds inside is due to the weld penetration which is a natural occurrence of a proper good weld. This can be rectified in manufacture by the method of purging, which involves sealing the ends of the cross pipe with masking tape or bungs, and filling the pipe with Argon gas constantly fed through a hose from the gas bottle during the welding process , This protects the weld inside the pipe from oxidising and it will form a neat bead just like the weld on the outside. This method is used in Aircraft work and stainless steel work for the food and Pharmaceutical industry where oxidised welds cannot be tolerated as it would trap contaminants. This method would be more time consuming thus raising costs...the extra Argon used would be very little though. As you rightly point out, those rough welds won't make that much difference to the escaping exhaust fumes. Thanks for a great review. I worked in Fabrication and Aircraft but now retired,

Refreshing to watch an honest review of an x-pipe for the Street Twin.  I bought one, along with the V&H mufflers.  Installed the mufflers without the dB killers, and am quite pleased with the sound.  I haven't installed the x-pipe, and after watching this video and others, I'm hesitant to do it.  I don't want to waste hours of my time installing something that's not really going to give me any more hp or torque, and make the exhaust sound more "raw" and "raspy".  If I get bored some weekend and absolutely have nothing better to do, I might get around to installing my x-pipe.  Or I could just gear up and go for a ride instead!

just bought a brand-new speed 900, your video is very useful

Thanks.  Great information.
All the best, David.

Great review Toni!
Have shared with my Triumph buddies in Sydney 🤘

Brilliant honest review   Toni

Love this non bull review, I was pleasantly surprised when I changed mine, that still had the stock pipes on. It did run cooler, it was a little livelier, and it was a bit throatier. I'm glad I did it, it was a bit of a pig, for an old git with no table, but its just nuts and bolts after all. Thanks Toni, you're definitely worth listening to  👍

I appreciate the honest review.

I thought the sound was a big improvement. Great objective review.

Every time I watch your videos I end up spending more money….thanks!! 😀

nice honest review, thank you so much.

Great, concise review. Thinking about doing a cat delete on my Speed Cup. Cheers Toni

Thanks Toni.

Great video! I'm 4 years after this was made but it's of course still very relevant. Your bike sounds awesome and I'm going to do the mod on a Thruxton RS. Cannot wait for the bits to come. Freespirits one from Italy, via ARH Customs in Blackpool. Euro5 version is over £500! progress eh. 🤣🤣
