sports exhaust

[chimi500]

Thinking of gettin a sports exhaust on my chim500 , has anybody delt with steve reid in cheshire he seems to be the cheapest , also do the factory themselves make and fit a sports exhaust?
Are there any downsides to gettin a sports , ie performance etc?

Don't get a new exhaust unless yours is buggered.

A TVR 'sports' exhaust is merely a standard exhaust that has had the wadding removed from the rear silencer and a straight pipe welded in.

You can get the rear box cut open and the work done, the box rewelded etc for £120-£150.

I agree. My Chimaera has had a straight-through job done (steady, boys!). No point changing the entire system for some extra burble...just whack a pipe straight through, and ooerrr! Extra snap, crackle and pop for not a wholelotta money

Sorry, but I thought this 'put a bit of scaffold in' thingy was a 'half-way house' between the standard exhaust and the sports exhaust.

After unintentionally "modifying" my original system somewhere over Snake Pass i was forced to buy a new one.
I fitted a (then)Wedge Automotive supersports system which has shorter than standard silencers.The quality of Stainless seems to be superior to the old system.
Allied to a partial de-cat (pre-cats removed) the noise is deeper with popping and banging on the overrun.
Not too noisy for (some)track days though,was measured at 96db last month at Oulton park.

My understanding is that the factory fit sports exhaust is just a standard one with a straight through pipe. Mine was a factory sports exhaust but too loud for track days and I had it returned to standard by the opposite procedure to that described above.

96dB sports exhaust? That's quieter than a normal exhaust isn't it??

Mine's been measured at 115dB with its straight-through modification
