CNT Racing 70 mm High Flow Catalytic Converter For 00-09 Honda S2000

Boosts sound

good quality, i have it paired with an invidia q300 and gave it a lil boost in sound. my q300 had zero drone before but after adding this, it added a tiny bit of drone at 3.5 rmps but i kind like it, not annoying like other exhausts. No CEL light yet after a week. hardly any smell but just barely, doesn’t bother me.

70mm High Flow Cat

Fit and finish are superb. Sounds great with UK mod mufflers. No CEL on my 07.
