Navigating Car Modification: Pitfalls and Tips for Exhaust Systems

Introduction:

The majority of people choose to modify their exhaust systems primarily due to dissatisfaction with the original sound, lack of a 'punch', and performance not meeting expectations. This article aims to shine a light on the common pitfalls encountered over years of vehicle modification, specifically focusing on exhaust systems.

1. The 'C' Number:

In car modification, the smaller the 'C' number, the louder the exhaust sound, and the greater the exhaust volume. A standard family car usually operates around 800-900 C. A 300 C front section strikes a balance between volume and smell, which makes it the preferred choice for most people.

For those who have upgraded the power program, 200 C is often chosen. Compared to 300 C, 200 C allows for a larger exhaust volume, better heat dissipation, and slight performance improvement. However, smaller brands' 200 C exhaust may smell a bit off; this is where bigger brands excel.

Performance chasers may consider 100 C, such as JBOM's Super 100 C. It emits less unpleasant exhaust odour, and there's not much drop in low torque. Its performance is good. For race track enthusiasts, a straight-through front section is recommended, although the downsides include unpleasant exhaust smell, loud noise, and a dispersed sound that may resonate.

2. Standard Exhaust Vs. Modification:

Ordinary commuting folks may simply pick a front section that fits their budget, as the front section does not hugely impact the exhaust's tone. But beware, inferior front sections may produce a dispersed sound and an unpleasant metallic knocking sound.

For a little more performance, you can opt for front sections from big brands. You get what you pay for, but unless you're racing on tracks or driving aggressively, you might not truly experience the difference.

From personal experience, my mkl300 C ran for a year before it broke. Luckily, I detected it early and switched to mach5's 200 C with heat insulation. It too cracked open after six months, so if you're racing on tracks, it's worth investing in better quality. With straight-through, this issue won't occur. I later switched to ibom100 C, which noticeably outperformed the 300 C. For some middle and rear sections, resonance can be an issue. The key is continuously tweaking, testing, improving, and choosing the right C number according to your needs.

3. Mid-sections with GPF:

Mid-sections carrying a GPF will also affect the exhaust volume, sound, and heat emission. The most economical modification would be to first cut the GPF. But note that some models may resonate, in which case, welding a shock block can be a solution.

Conclusion:

Car modification is a constant journey of learning and trial and error. Whether you're an enthusiast, a racer or just someone who uses their vehicle for everyday commuting, understanding the effects of modification on your car, especially on its exhaust system, is critical.

Remember to purchase from reputable brands and always keep an eye out for any potential issues. Your vehicle is an investment and should be treated as such. Happy Modifying!
