The exhaust is fantastic, sounds like a real V8 now and there’s no drone on lower RPM’s which is perfect for highway commutes.

I will say (this is likely not 10second racing’s fault, most likely MBRP) they accidentally sent me two left sided exhaust pieces, so the muffler shop had to weld a new mount on the other one to make it work and it ended up costing me an extra $100 in labor. That was frustrating, but I don’t want a logistics error to take away from how good the product is.

Item received in well pack packaging and shippinh was fast.

Without doubt the best pads I've used on my Kia Stinger. Stopped the vibration issue on stock pads and far better than other performance pads I've used. Bonus points for minimal dust on the alloys.

As ever, the guys at TSR, packed securely and shipped quickly to the UK. I couldn't ask for more

It arrived later than expected because i ordered from Europe. I contacted them and they kept me up to date about my order. It arrived in perfect condition.

There was a delay with my order. I e-mailed them and they were very helpful. They kept me up to date.

My first tuner for a Harley and I wish I had purchased it years ago. Super easy to set up and to tune the bike. It immediately ran better all the way around, idle, acceleration, and cruising down the highway. No more running too rich either.

works great

Accurate about what they have in stock. Fast shipping and I got exactly what I ordered.

Headers worked out great perfect fitment. Combined with the 1320 exhaust and blox racing extension. Sounds great and had great fitment

Arrived in good time to the UK - Exactly as Ordered

Great parts at a fantastic price and good service

Awesome edition to my wife’s Mustang

Made a big difference on my wifes Mustang that someone (me) may have put just a little bit to much cam in. Works great now.
