MGB Exhaust

MGB Exhaust Systems and Components at Rimmer Bros

At Rimmer Bros, we've established ourselves as the premier destination for MGB exhaust components. Our comprehensive range spans 4-cylinder and V8 applications, with options crafted to meet standard replacement and performance enhancement needs.

4-cylinder MGB exhaust options

Your 4-cylinder MGB deserves exhaust components that deliver optimal performance. Our standard mild steel manifolds provide original equipment specifications, while our stainless steel sports manifolds offer improved gas flow for enhanced performance. The difference in MGB exhaust sound between these options is notably distinct, with the sports variants delivering that characteristic throaty tone enthusiasts seek.

When selecting a complete MGB exhaust system, you'll find our one-piece, three-piece and five-piece configurations offer distinct advantages depending on your installation preferences. The standard stainless steel systems with bomb centre silencers have become particularly popular for MGB roadster applications, delivering a balanced exhaust note that's aggressive without becoming intrusive on longer drives.

MGB exhaust header options include both factory-specification and performance-oriented designs. Each is manufactured with precise fitment to ensure your MGB exhaust manifold gasket seals properly, preventing exhaust leaks from affecting performance and sound quality.

V8 MGB exhaust solutions

Your MGB GT V8 demands exhaust components that can handle increased thermal loads and flow volumes. Our standard V8 manifolds provide reliable performance, while our tubular sports designs - including our popular RV8-style options - dramatically improve breathing capacity. The MGB GT exhaust signature with our big bore exhaust system delivers an authoritative sound profile that announces your arrival with distinction.

For those seeking the ultimate performance, our sports stainless steel big bore systems maximise flow capacity while our specialised V8 fitting kits ensure proper mounting and alignment. Side exit exhaust options provide both aesthetic differentiation and practical ground clearance benefits.

Frequently Asked Questions

What are the performance and sound differences between standard and sports MGB exhaust systems?

Standard MGB exhaust systems prioritise OEM specifications and deliver a moderate exhaust note similar to factory fitment. Sports MGB exhaust systems feature improved gas flow characteristics through optimised pipe diameters and less restrictive silencer designs. The MGB exhaust sound notably differs between these options - standard systems provide a subtle tone, while sports variants produce a deeper, more pronounced note. Many MGB roadster owners prefer the balanced tone of our sports systems, which provide character without excessive noise on longer journeys.

How do I choose between mild steel and stainless steel for my MGB exhaust system?

Your decision between mild steel and stainless steel MGB exhaust components should consider budget and longevity. Mild steel systems provide correct fitment at a lower initial cost but generally have a shorter service life under British weather conditions. Our stainless steel MGB exhaust systems cost more but offer substantially longer service life with proper care. The MGB exhaust manifold gasket seals equally well with both materials, but stainless components maintain better alignment over time due to reduced corrosion at mounting points. MGB GT exhaust systems in stainless steel are particularly popular due to their improved appearance when viewed from behind the vehicle. For those planning MGB exhaust back box replacement, investing in stainless eliminates repetitive future maintenance. We provide comprehensive fitting kits with both material options to ensure secure mounting.

Which MGB exhaust header and system configuration is best for my specific model?

Your MGB's year and specification determine the optimal exhaust configuration. Pre-1975 models benefit from our three-piece systems with separate MGB exhaust manifold components, while later cars typically use the five-piece arrangement to accommodate catalytic converter positioning. The MGB side exit exhaust option is compatible with all Roadster models but requires specific mounting hardware we supply. MGB GT exhaust routing differs from Roadster applications particularly at the rear section - our dedicated GT systems account for these differences. V8 conversions demand our MGB big bore exhaust, which provides 20% greater flow capacity than standard systems. The specific exhaust header design significantly impacts performance - our V8 RV8-style manifolds deliver optimal gas flow while maintaining heat shield clearance. Customers choose Rimmer Bros because we provide model-specific solutions with precise fitment documentation, eliminating guesswork and ensuring proper alignment throughout the MGB exhaust system.
