Mate would love that.
V6 Ecotec, street 3 into 1 - specifically these - VT VX VU VY V6 Holden Commodore 3 8LTR Stainless Steel Extractors Headers NEW | eBay
These are 2mm wall 305 ss with 1 5/8" primaries and 2.5" collectors. Going to run ballistic 100 cell cats, not sure whether 2.5" will do, considering 3" but dont want to reduce gas speed, to 2.5" twin system with merge pipee from sureflo - Sureflo Exhaust
Thesze are the parts from sureflo - and prices if anyone cares.
The ballistic cats are $170 each for the 4” body
The merge pipe is $75 in stainless
The inline offset stainless mufflers are $220 each
The 8” round twin stainless muffler is $280 and you only need one of them.
Freight would be $45
The ebay extractors sound cheap and look good.
Just make sure they are not 1.0 – 1.2mm thick.
They really need to be 1.5mm thick stainless, otherwise they will crack or warp.
The system is currently a slightly modified ecotec running a raptor water cooled Supercharger, with billett race spec billet impeller, water meth injection and high ratio rockers (1.95). LS1 maf and a complete retune on 40lB injectors.
Current exhaust is 1 3/8" primarys, into single 2.5" system with no name sports exhaust and resonator.
Current dyno results on a 37 degree day are 328RWHP, 208kW, with just shy of 12kNM tractive effort, through a 4L60E and 8" HSV LSD with 3.7 gears. I think the dyno sheet is in my profile.
My best guess is that I'm actually substantially restricted by the current exhaust - it has some 90 degree non mandrel bends and a single 3" 100 cell cat. I could see as much as 30rwhp shifting to a better system.
Also note this - there is a new engine coming (eventually) with ZZP heads, oversize valves and a port job, converted to 80lB injectors to run E85 with a target RWHP of 400+. I'd like the system to handle that as well, even if it's a bit too large for the current engine.
Cheers
