TEC Designed and Manufactured

Inspired Design: Our exhaust system pays homage to the iconic swept-back and megaphone systems that were beloved by the Rockers and Cafe Racers of yesteryears, giving your bike a classic and timeless appearance.

This upgrade enhances your motorcycle’s overall performance.

Perfect Fit and Aesthetic Appeal: Engineered to seamlessly hug your BSA 650 Gold Star, our exhaust is designed to look “just right” on your bike, providing not only enhanced performance but also a stunning visual upgrade.

Authentic Sound: Experience the nostalgia of a 1960s bike with the distinctive and captivating sound produced by our custom exhaust, adding to the overall riding experience.

Designed for Stock ECU: Our exhaust system is designed to seamlessly integrate with your stock ECU system, eliminating the need for retuning. It ensures an easy and hassle-free installation.

Improved Engine Performance: Our exhaust system allows your engine to breathe and rev more freely whilst unlocking its full potential.

Premium Construction: Crafted from high-quality 304 stainless steel, our exhaust system is built to withstand the rigors of the road, ensuring long-lasting durability and performance.

Optional Joint Cover/Heat Shield: Enhance both functionality and aesthetics with the optional polished stainless steel joint cover/heat shield, providing additional protection and a polished finish.  Pictured with and without shield.

Detailed Installation Guides: We provide full written and video instructions, making it straightforward for home mechanics to install the exhaust using basic hand tools. The kit includes all the necessary parts, including gaskets, for a hassle-free installation.

Rocker exhaust

I am over the moon with this product. Easy to fit and well made. Excellent sound, but best of all the difference it has made to the bike. The engine pulls far more readily because the thing can now breathe properly. It as improved the look of the machine and has of course reduced the weight. This along with the other TEC part I bought the other day (Tail tidy) has made a massive difference to the overall aesthetic of the bike. Well done TEC parts.

Great exhaust

Video shows how to remove the old and fit the new exhaust and it’s really clear and easy steps to follow. Exhaust sounds and looks great definitely an improvement over the stock system .only downside I’ve come across is with the exhaust and the tec bobbins I’ve fitted adjusting the chain is a bit of a chore as I needed to remove the exhaust cone to get access but easy to do as only 2 fixings . Apart from that great exhaust and great service from the supplier

Très facile à monter

Très facile à monter, très belle sonorité, nécessite quand même un joint entre le silencieux et le tube

Exhaust and tail tidy

Excellent service by Tech, YouTube videos helped in fitting exhaust and tail tidy. Both quality products, exhaust is a massive improvement, sounds great and more responsive, tail tidy makes the bike look so much better and more original.

Goldstar exhaust

I received my exhaust on the day promised,, On opening the box (which was very well packed) I looked over my exhaust carefully and found it in perfect condition,,all the parts were present and correct.The fitting process went very smoothly as I followed the instructions to the letter..The finish on the exhaust is superb.. The only negative I found,is I would have like to have a second bracket on the front pipe similar to the stock pipe ,,but thats just my opinion...I have it fitted but as the bike is still SORN it will not be ridden until next May(Unfortunately) Yes I wholeheartedly recommend !

BSA Rocker Exhaust

Fast delivery and arrived well packed. I polished my system and then lightly finished with a scotch pad. Easy to install once you have watched the Tec video. So much lighter than OE system and the sound is now just right for my ears!

Rocker exhaust

Superb exhaust looks and sounds great and very clear instructions and advice. My only negative is the exhaust cover near rear foot peg is naff it could do with a better shape to it to contour the down pipe. It spoils the look.

Rocker Exhaust System

A very nice system and at a good price. Easily fitted after following the instructions both printed and on the video. Looks and sounds good. The downpipe does brown with heat but I do not see that as a problem and the advice to leave off the superfluous cooling fins originally fitted is good.

A quality system that looks and sounds brilliant.

This exhaust system is very well made and fits perfectly. Looks so much better than the original and sounds much better too without being too loud. TEC bike parts have got this just right. Very easy to fit especially following the video. Fitted mine in about 30 minutes. The bike is now noticeably lighter and seems more lively. The cherry on the cake is the excellent price. Very good value for money. Thoroughly recommended.

Classic sound!

Great sounding exhaust, much more authentic than the stock system, gets rid of the cat too. Huge weight saving (about 5/6kg), only slight negative is that the header pipe is subject to blueing and bronzing even without the header heat shield fitted. In my opinion this adds to the overall classic look, but may not be to everyone’s liking. Very happy with the overall style and sound though.

Great sound!

Exhaust is relatively easy to fit, huge weight saving and sound epic. Just one thing, even with the header heat shield removed it’s subject to lots of blueing and bronzing on the header pipe. Doesn’t bother me in the slightest but it may be a problem if you’re not keen on that aspect.

Tec 'Rocker' rocks!

Just fitted my new 'Rocker' exhaust from Tec and I'm absolutely chuffed with it.! It was easy to install and the instructions are very clear for those who need them. The pipe sounds awesome with a nice deep and mellow tone and the bike definately pulls better on acceleration so thankyou again Tec for producing the goodies we need to improve our modern retro bikes at very fair prices. Very much looking forward to more gold star bits!
