Incomplete Guide To Exhaust System Upgrades, 99% of People Have Never Read It

As a brand that has been focusing on car modification for 10 years, GRWA often encounters questions from customers about how to avoid "stepping into pits" during exhaust modification. Today, we have compiled an incomplete guide to modification to help you easily overcome the obstacles in the modification process.

It is said that modifying the exhaust will cause loss of low torque. Is this true?

Many customers ignore the pipe diameter when purchasing exhaust pipes, and many even think that the pipe diameter is universal. In fact, the exhaust pipe diameter will affect the performance and emissions of the vehicle. As we have said before, a diameter that is too small may Exhaust resistance will be increased, and an excessively large diameter may result in low torque loss.

In fact, the reasons why low torque is lost when modified exhausts are mentioned often come from insufficient understanding of accessories. You must know that the entire exhaust system contains dozens or hundreds of accessory types. For example, the exhaust type is S The difference between drums and M drums, S drums and M drums mainly refers to the structural differences in scheduling design. Simply put, the pipe directions of the exhaust pipes are different.

These different designs and types produce different effects. If you want to achieve the effect of modification and upgrade and achieve the ideal modification goal, you still need to consult professionals.

What should We do if there is resonance in the exhaust after modification?

Resonance is the most common problem in the exhaust system. As far as the modification process is concerned, the first thing to check is whether there are quality problems with the modified accessories. I have to mention a customer We met this year.

In November this year, we attended the SEMA show in Las Vegas and met a car modification club owner named Kris. Kris also very enthusiastically invited us to visit his club after the show. What is surprising is that the club is empty. After careful investigation, I found out that the club has been open for less than 2 years, and Kris has only enthusiasm and no experience in modification.

This resulted in his original supplier always substandard quality. This led to Kris's car owners often reporting to him that car resonance occurred after modifications. When Kris realized that this was a major quality incident, the customer More than half has been lost.

So Kris used the time at the SEMA exhibition to inspect many brands and finally chose us. He said that our service attitude was very sincere and the quality of the samples on site was also outstanding in the entire exhibition, especially after learning about GRWA's development history and cooperative brands. Finally, Kris established a long-term cooperation with us without hesitation.

In fact, inferior exhaust products always have the following characteristics in common:

• Rough appearance: The appearance of inferior exhaust products is usually rough, with uneven welds and even obvious flaws and bubbles.

• Harsh sound: Inferior exhaust products usually have poor muffler effect, and the sound is harsh and unpleasant, which can easily affect the driving experience.

• Thin and light materials: Inferior exhaust products are usually made of inferior materials with thin pipe walls, which are prone to aging, deformation and other problems.

• No quality certificate: Inferior exhaust products usually do not have quality certificates and warranty terms, and cannot be guaranteed after purchase.

In the final analysis, only by choosing high-quality products can you avoid these problems after modification. Therefore, choosing high-quality exhaust products is the most important step to avoid modification pitfalls. You can inspect product quality in terms of product materials, processes, welding, surface treatment methods, etc., and at the same time choose brands with rich heritage and service experience. Such brands usually have better quality control systems and after-sales service systems, and have stronger guarantees. .

Does the modified exhaust pipe require maintenance?

Whether it is a modified exhaust system or an original exhaust system, regular inspection and maintenance are required. On the one hand, ensure that the exhaust pipe is not leaking or damaged, and on the other hand, check the usage of modified accessories, especially the three-way catalytic converter and muffler. The two most common accessories need to be replaced to avoid more serious consequences caused by corrosion, aging, deformation and other problems.

Through the above Q&A format, we introduced in detail how to avoid pitfalls in exhaust modification. We hope that car enthusiasts can be more cautious and rational in choosing products and service providers that suit them when performing exhaust modifications. We, GRWA, will always adhere to the bottom line of quality and provide you with the safest and most efficient exhaust modification solutions. . I hope this guide can help you easily overcome every pitfall of exhaust modification!
