Steve Robinson Posted December 9, 2002 Share Posted December 9, 2002 My SLR runs at about 100db so gets me into trouble at some track days. Recently at Goodwood the nice guys at BaT lent me a great bit of kit, it was a sort of cone with a mesh grill that bolted over the end of my standard exhaust and cut the crucial few db from it. Have looked in the DT catalogue and found nothing, anybody know where I can buy one of these beasties from (assuming my description was good enough so you know what I mean).

paulyb Posted December 9, 2002 Share Posted December 9, 2002 Most of the tracks / trackday companies have them and will lend them out at the quieter tracks where needed. I also borrowed one for my SLR at Goodwood a while ago, though still marginal on noise. Have never managed to find one in DT...etc, but last time I was at Goodwood I asked them, and was told I could keep the one I'd been using all day!!! Might be worth a try next time you are there.

F355GTS Posted December 9, 2002 Share Posted December 9, 2002 Steve Goodwood Circuit will sell you one for £50 IIRC Mark Link to comment Share on other sites More sharing options...
rgrigsby Posted December 9, 2002 Share Posted December 9, 2002 But be careful using them... they have a nasty habbit of making everything run a lot hotter and in the worst case scenario can cause engine damage (a friend with a Radical ended up with a warped block/head after running at Goodwood with one of their add-on silencers in all day!!) Having said that I've used them and they seem OK although it did make the engine breathless at high revs and definetly caused a drop in power at the top end. Ultimately if you can afford it you'd be better of getting a bigger/better silencer from Techcraft/Powerspeed/BTB etc etc Cheers Rob G www.SpeedySeven.com Edited by - rgrigsby on 9 Dec 2002 11:01:31 Link to comment Share on other sites More sharing options...
Steve Robinson Posted December 9, 2002 Author Share Posted December 9, 2002 Hmmm, the bit about damaging the engine has made me think again. Maybe I'll have a chat with Chris Wheeler at Seven Workshop about new silencer instead. Cheers all. Robbo Link to comment Share on other sites More sharing options...
Bilbo Posted December 10, 2002 Share Posted December 10, 2002 Hi Steve Chris fitted a BIG (same diameter as R500 7" ?) repackable Techcraft silencer to my car. At least I can now replace the wadding that leaches away over the miles ❗. He also modified the collector box to suit the bigger inlet pipe diameter. Its now much quieter but borderline at some places Goodwood 🤔 no chance peaking at 8400 rpm on the change. 'Can you hear me running' ......... OH YES and its music to my ears 😬 😬 😬 1988 200 bhp, 146 ft lbs, 1700cc Cosworth BD? on Weber's with Brooklands and Clamshell wings, Freestyle Motorsport suspension.
