What is a Rear Silencer?

A rear silencer sits at the end of the exhaust system and connects to the exhaust pipe. Like the front/middle silencer, its primary function is to reduce noise and engine vibrations and emissions before they're released into the air through the exhaust pipe. 

Over time, rear silencers wear, sometimes cracking or getting holes in them. You'll certainly notice when it does because the noise is loud! So, if your rear silencer fails, you must get a replacement as soon as possible. Not only will it dampen performance and affect fuel economy, but the noise will also just be embarrassing!

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.
