: Always check for clearance (aim for 1.5 to 2 inches) around surrounding parts to avoid rattling or heat damage.

: Cheaper "straight pipe" designs can produce an unpleasant interior resonance.

: Systems made from T304 Stainless Steel or Titanium are highly recommended for their resistance to rust and corrosion.

💡 : If you want the best of both worlds, consider an active valved exhaust (like those from Remus ). These allow you to keep the car quiet for daily commutes but open the valves for a "racecar" sound at the push of a button.
