SB class??

[Gunnie]

Ive bought myself a car for this years championship and have entered in the standard class. My question is that the exhaust on the car is a pattern replacement fitted by the last owner. Its not a performance enhancement but gives the car a nice sound.

Will i be able to use the car with this exhaust on or will i need the standard exhaust fitted,

Thanks

Personally i would have thought pattern replacement was ok providing the exhaust is the same diameter pipework with no box's removed, as exhausts don't last forever. The fact that the sound has changed should not make a difference but i'm not competeing in STD class.

Clarifications for Road-going Series Production Cars

These classes are intended for near-standard cars with very few modifications (as listed), to
encourage low-cost entry into the sport. All cars running in the above classes must remain in
totally road legal form at all times.
All cars must have current VED & insurance in the name of the main driver, with a current MOT if age
requires it.
Note. Trade plates and traders or company group insurance policies will not be accepted.
NO modifications (optional or otherwise) are permitted which are likely to improve the performance and
handling of the car with the following exceptions:
Wheels & Tyres; The standard wheel rim width may be increased by a maximum of one inch and fitted
with tyres to suit. Tyres must be from MSA list 1A and be Road Legal.
Engine, Induction & Exhaust; The air cleaner and exhaust system must remain as production or OEM pattern replacement including catalyst if fitted. Electronic ignition may be fitted.
Suspension & Steering: The steering wheel may be replaced by a non-standard item. Uprated dampers
may be fitted.
Brakes; An alternative or OEM pattern replacement brake friction material can be fitted, but modifications
to the brake disc, caliper, drum or shoe are not permitted.
Body; In the interests of safety front seats may be replaced by competition versions which must be fully
trimmed, not a bare shell. Loose over-mats may be removed but the original carpets, fixed floor mats, and
floor trim, etc, must remain and in their original locations. Pyrotechnic safety devices such as airbags and
seatbelt pre-tensioners may be disconnected or removed.
General; The spare wheel and any mounting or cover which is not permanently fixed to the body may be
removed.
No other modifications, except the fitting of a roll cage, are allowed in classes SA, SB and SC.
Kit cars, limited production cars, space framed or non-ferrous chassis construction road cars and one-off
road-going cars are not permitted in Classes SA, SB and SC.
In the event of an unresolved eligibility issue, the driver of the car concerned may be required to produce
within four weeks of the event in question, a manufacturer’s catalogue to substantiate any queried
modifications / specifications and allow championship points to stand.
Any modifications not specifically permitted are, by definition, not allowed.
