Clarkey Posted February 28 Report Share Posted February 28 Fellow forumites now on my second Pheonix sports exhaust back box. My first after a coupe or years and trips to Lemans stated to sound whistley on acceleration. So spoke with Pheonix and the sent me a replacement at cost as the warranty had run out. The second has only done around 1000 miles and this one is starting to sound the same. has anyone else had issues, is it worth another go or is there a better alternative regards Clarkey Quote Link to post Share on other sites
Andy Moltu Posted February 28 Report Share Posted February 28 The old “wheelbarrow handle” twin sports system used to be prone to whistling/twittering. Not sure if that was a Phoenix product. Quote Link to post Share on other sites
BlueTR3A-5EKT Posted February 28 Report Share Posted February 28 The mild steel twin pipe system originally sold by SAH then Triumph Tune had silencers made by Servais. They would whistle after a year or so if they had been grounded. The inner baffles were knocked loose, then the outer skin would crack and split. The Phoenix sports is a single cross box system so who knows what is going on inside them. Ask Phoenix, they seem a very approachable company Quote Link to post Share on other sites

My pipes and manifold are Phoenix but the box is not. Roger Quote Link to post Share on other sites
harlequin Posted February 28 Report Share Posted February 28 I had a local company that makes motorcycle silencers repack my Pheonix standard across the car silencer. It had become noisy after a decade of use but once repacked it is as good as new. George Quote Link to post Share on other sites
Clarkey Posted February 28 Author Report Share Posted February 28 Thanks all Roger what box did you go for ? Quote Link to post Share on other sites
RogerH Posted February 29 Report Share Posted February 29 Nothing special. Either Moss or TRShop general offering I bought it ages ago and I've repaired it many times. But sounds good. Roger Quote Link to post Share on other sites
FatJon Posted March 8 Report Share Posted March 8 I have a phoenix wheelbarrow system on my TR6 without problems, installed in 2020 I think. Quote Link to post Share on other sites
Nigel Triumph Posted March 10 Report Share Posted March 10 I fitted a Phoenix system with transverse backbox to my '6 over 15 years ago. To start with, it was quiet with a sporty sound. Within the first 1,000 miles it grew much louder, presumably as some of the packing was blown out. Years later, the sound hasn't changed much. It has never whistled or rattled.
