One of the first steps to increase the performance of your BMW 335i can be done by adding one of the best 335i exhaust systems. Picking the best 335i exhaust for your power producing inline-six not only gives your 335i a better sound, but when it’s properly tuned it can deliver a whole new driving experience without breaking the bank or sacrificing reliability and durability. A great 335i coupe exhaust, sedan exhaust, or even for your wagon can help make your BMW stand out in all the best ways. Here are some of the best BMW 335I exhaust system options we’ve found just for you.

1. Rev9 CB-211A_1 Stainless Steel Axle-Back Exhaust System w/Carbon Fiber Tip
1027505

This exhaust from Rev9 goes from the axle back and bypasses your factory mufflers without replacing them. No mufflers mean more flow and more noise, and while relying on the turbocharger and catalytic converter to do all of the quieting might not pass muster with your local constabulary, it's not uncommon even on factory fresh performance models. If noise rules aren't a problem for you, this exhaust for BMW 335i F30 sedans will let the N55B30 engine in your 2012-2015 car sing. Stainless steel construction with 16-gauge piping should offer a long exhaust life and stay looking shiny and fresh, while skipping the muffler allows for maximum flow and loads of deep and rich sound. The pipe size is the stock 2.5-inches leading to a pair of 3.5-inch diameter carbon fiber-look tips. This system fits both rear and all-wheel drive models of that generation sedan and comes with all of the installation hardware needed

Pros: Comes with all hardware
Cons: No muffler, requires cutting of factory system

2. Tunerbits Stainless Steel Full Cat Back Exhaust for BMW 335i E90
1027506

A low-cost option for anyone looking to replace the exhaust on their E90 BMW 335i, this system from Tunerbits replaces everything from the catalytic converters back. A dual exhaust with H-pipe crossover to even out flow pulses, the system gives you two new mufflers as well as two resonators to give you more sound without being overbearing or making your neighbors angry. A 335i exhaust for coupe or sedan, though not for Drive all-wheel drive models, the twin double-walled exhaust tips are a four-inch diameter to stand out in your bumper with burnt-look tips to help your car stand out even more. All gaskets, bolts, hangers, and other hardware are included with the kit saving you from parts-chasing runs when you're halfway through installation. It's advertised as stainless steel, though at this bargain price we wouldn't expect the corrosion resistance and longevity of pricier systems so keep that in mind.

Pros: Affordable price, burnt tips
Cons: Low price may mean shorter life

How to Pick the Right 335i Mufflers?
The best way to evaluate an exhaust is to listen to it. That's not always possible, so turn to video sites like YouTube to look for the brand you want on the car you want and listen to exactly how that e92 335i exhaust sounds. After that, look for completeness of kit and warranty, as having to buy loads of extra hangers, clamps, and hardware can cost you loads of cash down the road, while an exhaust with a taillight warranty could lead to quick replacement and more pain down the road. If your budget allows, stick with known names as they're more likely to have put in the work and development to make the best exhaust for your BMW.
