76mm Engine Protection kit
"Jim, I want to keep my factory exhaust with its amazing howl but I want to tune for more power and torque!"
You need to get rid of those horrible log-manifolds with their integral UTC (Ultra Thin Catalysts). Only 2bular supply stepped 48mm 3-1 manifolds with hand-fabricated merge collectors + 57mm diameter downpipes. ONLY 2BULAR.
If you need a catalyser (and most countries require one) you need the big 130mm diameter HJS HD 200cell design. 70mm pipework to the 2bular downpipes but I use a 76mm exit pipe to allow fitment to the factory exhaust system. V-band connector on the catalyser. Only 2bular can do this for you.
Supplied with all gaskets/fitting kits and the extended wiring kit for re-located Lambda sensors.
