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 factory 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.
YOU SEE THAT THE MANIFOLDS/DOWNPIPES AND DOWNPIPE TO CATALYSER JOINTS ARE BOLTED FLANGES. THE EXHAUST MUST BE FULLY SEALED/GAS-TIGHT BEFORE THE CATALYSER.
GIVEN THE EXCESSIVE ENGINE/TRANSMISSION MOVEMENT ON THESE CARS, USING SLIP-ON JOINTS WITH HOSE CLAMPS IS NOT A WISE MOVE. LIKEWISE SLIP-JOINS AND SPRINGS - IGNORANT.
AND ANOTHER THING; YOU NEVER WELD A BRACKET ON THE EXHAUST IMMEDIATELY AFTER A FLEXY SECTION. INSTEAD OF FLEXING, IT IS FORCED TO BEND - AND THEN IT WILL SPLIT.
If you need a catalyser (and most countries require one) you need the big 130mm diameter HJS HD 200cell design. 70mm pipework from 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 offers this quality.
Supplied with all gaskets/fitting kits and the extended wiring kit for re-located Lambda sensors.
Lead time for order: 1 month.
