Does welding the exhaust pipe have any impact?

Welding the exhaust pipe back has no impact. A broken exhaust pipe can be welded. Waterproofing during rainy day car washes: When driving in the rain or going for a car wash, be careful to prevent water from entering the muffler, which can cause rust and affect the exhaust pipe's performance. Rust prevention is important: Remove the muffler, block the drainage holes, add rust-proof oil evenly inside the pipe, and reinstall the muffler. Cleaning is essential: The main substance emitted from the car's exhaust pipe is soot, primarily carbon deposits. Since the exhaust pipe is often exposed outside and connected to the car's interior, accumulated dirt inside can affect normal operation. Regular cleaning of the exhaust pipe is necessary.
