Triumph TR4A stainless steel exhaust
Custom Built Performance System
Original Triumph TR4A is built in such a way that it causes excessive back pressure which does not allow the engine gasses to vacate quickly causing loss of performance and excessive fuel consumption. Most original exhaust systems are made of mild steel, which can deteriorate over time and when the time comes to replace it, the dealer replacement parts can cost anywhere into the thousands. We have the perfect solution for your Triumph TR4A , we can replace your existing exhaust system with a custom built bespoke T-304 grade stainless steel exhaust, which comes with lifetime warranty, we will only supply high quality branded Magnaflow and Profusion components and fabricate the exhaust for a perfect fit.
With a massive range of mufflers we can help you achieve the perfect sound you require; your choices are quiet mid or loud. Our mufflers have been dyno tested to deliver Quality, Power and Sound. The Wide open technology allows your engine to breath freely without restrictions which in turn delivers an increase in performance.

I had a stainless steel exhaust built by another company for just £400 but noticed that after 1000 miles the car had become significantly louder to the degree it was embarrassing, having trawled the internet it emerged that the company who did the work had supplied a muffler that cost them £7 now once I got my breath back, I was so please I had found Profusion and Raj, who did the work deserves every praise I can give, he was so professional with his approach, he told me very clearly what my options were and we agreed on having the system replaced with Magnaflow mufflers and my god what a difference, the sound is just right, I am only disappointed I did not find them sooner, but it was my fault for trying to save money.Thank you Raj. – Lloyd Deakin
I was recommended to use Profusion Customs for a first class job, I did and bought my mate a drink for sending me to you guys. I was pleasantly surprised how little it did cost. Many thanks. – Samuel Johnson
I hope you guys will use my testimonial on your website because people deserve to know, I went to XXXXX XXXXXXX to get my single exit exhaust changed to a dual exit, once they did the work I did notice that the exhaust smoke was just emanating from one tip on one side and not the one they had made, when I asked them about it they said it will take a little time, so be patient, as an accountant I did as they said having spent £350 for the work, 6 months later I noticed that one of the tips started to change colour but the other one was still shiny, I went to profusion customs for a second opinion and when the car was on the ramp I looked at what these crooks had done to my car I was horrified, all they did was weld a straight pipe from one tip to the other, Profusion Customs told me what needed to be done to get it right and I can recommend them to anyone, don’t go anywhere else just trying to save a buck get the job done once and get it right. I’m sure you have heard this before but I wish I found you earlier. – P. Kumar.
