Looking for Exhaust Recommendations for My BMW 330i

Has anyone had issues with drone on the highway? I’ve heard mixed reviews about aftermarket systems causing cabin noise during longer drives.

I didn’t experience any drone with my Remus exhaust, but some other brands can be pretty loud. Make sure to check reviews before you buy.

I just completed my exhaust upgrade and documented the entire process with step-by-step photos! If you’re interested, I can share it with you all.

For a DIY installation, don’t forget to grab some high-temperature exhaust paint! It helps protect the system, especially if you plan to keep your car for a while.

That would be amazing! DIY guides are so helpful for us beginners.

Great tip, @steven50! Also, using decent quality clamps makes a huge difference in preventing leaks.

Do you think a cat-back system is worth it? I’m torn between it and just a muffler delete for sound improvement.

Cat-back systems usually provide better performance and a deeper sound. Muffler deletes are noisy, but you might have to deal with drone.

Just thought I’d share my experience: went with a cheaper option and regretted it. Save up for a quality exhaust; it’s worth it in the long run!

Agreed, I made that mistake once. That said, humorously, my cheap system did sound like a foghorn!

Can’t wait to get started on my exhaust! I’m feeling motivated. Any last minute tips before diving in?

I’m in the same boat! Modifying the exhaust can enhance performance, but one needs to consider emissions regulations. Check your local laws before you dive in.

If you’re in CA, just be careful! The laws are quite strict here for emissions. Always look for CARB-compliant parts.

Absolutely! In some areas, you might need to pass emissions tests that can be impacted by exhaust modifications.

Good point! I live in an area where they don’t even do inspections. Still, I think it’s prudent to be aware of the law.

Don’t forget potential warranty issues! Altering the exhaust could void your warranty, so check your vehicle’s policies.

Supporting local emissions standards is key, but it seems like many people aren’t aware of this when modifying their cars. Let’s promote being responsible car enthusiasts!

Exactly! Knowing the local regulations would save a lot of headaches during inspections.

I have a friend who modified his exhaust only to be hit with hefty fines. Do your homework first! It’s not all fun and games.

I’m concerned about sound limits too. Some states have strict noise regulations that can result in fines during inspections!
