OUT OF STOCK TILL END OF MAY. UPDATED FOR 2011 WITH A PURPOSE BUILT HIGHER FLOWING 200cpi METAL SUBSTRATE CATALYTIC CONVERTER
With this 2011 update, the MadDad Metal Bellmouth inherits the new purpose built 200cpi metal substrate cat used in our recent Street Series bellmouth for the 2008+ models. Most of the metal substrate downpipes on the market today use a 300cpi cat, and while good, they are more restrictive than our new 200cpi units, A MadDad 200cpi Metal Bellmouth blurs the line between catless performance and catted cleanliness.The MadDad(TM) Metal Bellmouth is a full 3" and you should mate it to a true full 3" catback. There are no 2.5" tapers or provision for the "donut gasket". A 5-layer metal OEM gakset is included at no charge($20 value) as well as a 3" gasket at the catback mating side. An extra 02 bung is included in the head of the bellmouth for dyno tuning sessions or to run a widebande A/F gauge. A plug for the extra 02 bung is also included.
