Is your car’s physique exceptional? Even if you’re in need of an exhaust configuration that’s as one-of-a-kind as your build, don’t worry; we’ve got you covered. You may make that one-of-a-kind as Bmw 330i custom exhaust in your garage by following the construction suggestions provided below. There are certain tried-and-true methods for creating a high-quality bespoke exhaust system that will not only function well but also look great. Magna Flow has everything you need to create a unique exhaust system, and we’re happy to share our expertise with you.
Tools
A welder will likely be needed for any sort of custom work, with the exception of installing an axle-back or cat-back exhaust system. There are a few choices for welding stainless steel. Electric arc welding is used in both MIG (metal inert gas) and TIG (tungsten inert gas) welding. The arc is used differently in arc welding and arc arc welding, respectively. In MIG welding, a feed wire is fed into the gun and melted into the weld with the help of a spark electrode, making the process similar to using a hot glue gun for metal. In contrast, TIG welding may be used to permanently join two metals without the need of any filler material. Using a filler requires manual handling of the filler.
TIG welding
TIG welding is a great option for a skilled welder to use. However, MIG welding is recommended for beginners since it is easier to learn and use. So, try it out on some junk first before attempting your exhaust. Having a welder of your choosing and all the required safety gear is crucial. Wearing proper eye and heat protection is essential during welding. It is also recommended that you use sunscreen on any exposed skin before welding.
You can cut down on exhaust fabrication time by a lot if you have access to a band saw and a grinder with cutting and sanding discs. While it is possible to cut pipe without these tools, they will prove invaluable if you want to create many bespoke exhausts.
Initiation Procedures
Just as crucial as having the necessary equipment for the job is making sure you have easy access to your car’s undercarriage before beginning any exhaust work. We recognise that not every do-it-yourselfer has access to a two-post lift, despite its obvious usefulness (and “garage ambitions” status). In light of this information, we advise jacking your automobile as high as possible and, as with any endeavour, prioritising safety above all else. When operating beneath a vehicle, jack stands are an absolute need. Before getting beneath the car, make sure you’ve jacked it up properly and are supporting it in the right places.
Elaborating a Strategy
Several factors, including routing and clearance, should be taken into account while planning your exhaust system. You want to make sure that your exhaust system does not touch anything beneath your vehicle, as contact with either the chassis or other components will likely generate unpleasant rattles, destroying the enjoyment of your new exhaust tone.
Exhaust components also grow very hot, thus it is crucial that your exhaust system is routed away from floor-mounted master cylinders, brake lines, the starter, solenoids, and any wiring. Keep in mind that carpet and insulation placed to a metal floor pan are potentially combustible, so leave ample room to keep things cool. In addition to providing your running gear and chassis some breathing space, you’ll want to offer the road some as well. Ground clearance, especially on streetcars, is always crucial for drivability. It is recommended that the exhaust system be tucked as far up on the vehicle as feasible, and not allowed to dangle lower than the lowest point of the undercarriage. Typically, the lowest point of a rear-wheel-drive vehicle is the rear differential, however this varies from model to model.
Collectively Tied Together
Compression bent pipes are often used in factory exhausts and custom exhaust systems. This method involves compressing the pipe to generate a bend. Because the inside diameter of the pipe is reduced throughout the curved portions, this bend might cause exhaust flow restrictions. In contrast, MagnaFlow is focused on flow. When it comes to exhaust systems, mandrel-bent piping is the way to go since it keeps the pipe’s internal diameter consistent even as it bends. MagnaFlow uses mandrel-bent pipe in all of its exhaust products because it improves performance. Creating a bespoke exhaust with mandrel-bent pipe needs a little more work in terms of cutting and welding, but the improved performance and bragging rights are well worth the effort.
It is also recommended that when joining sections of pipe, tight joints be made and that reference markings be made on both sides of the connection using a permanent marker. Welding will go more smoothly if the joints are as tight as possible since there will be less space to fill. Making reference markings will also guarantee that your components are correctly timed when you want to tack weld them, saving you time and effort in the long run.
