Our selection of middle silencers come from reliable and trusted exhaust specialists, so you can be sure you're purchasing quality components that will do the job.

What is a Middle Silencer?

Depending on your vehicle's exhaust system set-up, the middle silencer (middle box or front silencer) is the silencer first in line to receive the exhaust gases from your engine. It's situated in the middle of your car's exhaust system and is engineered to control noise and vibrations from the engine and clean the fumes before they move further down the exhaust system.

A cracked or damaged middle silencer will make a loud noise when the engine runs. There also could be a hissing sound from a leaking gasket or a chugging from a blocked exhaust system. If you notice any of these symptoms, you must immediately check your exhaust and replace it if necessary.

What Other Car Parts do we Stock?

At GSF, we stock a great selection of exhaust components to keep your vehicle’s exhaust system in check and working perfectly. This includes the exhaust pipe, manifold, front, middle and rear silencers, and of course, the catalytic converter.

Different coloured smoke coming from your exhaust pipe could be a further issue with your exhaust system. With our detailed exhaust smoke guide, you can troubleshoot the problems with your exhaust easily and quickly. And these days, catalytic converter theft is big business; our handy guide shows you how to secure your catalytic convertor safely so you don't become a victim.

And, for a complete overhaul of your engine, we stock a vast range of crankcases, crankcase drives, cylinder heads, engine mounts, gasket sets, camshafts, and breather valves, plus a steady supply of automatic and manual transmission parts for various vehicles. 

We have a full range of car parts for other repairs or servicing on your car, from service, engine, transmission, exhaust, electrics, fuel and emissions, braking systems, and cooling and heating parts. All are sourced from our trusted and reliable auto partners.
