Hello Again
So yesterday Arvo I installed a complete exhaust system into my VY Calais SII 3.8L
Proflow tuned 2.5" extractors
2x 100 cell cats
Xforce twin 2.25" cat back
So I fitted everything up on a hoist at a fabricators who let me used their workshop,
We don't have a exhaust specialist in town anymore so had to do it myself
Everything went in nice and easy
Just had to get the fabricators to weld up the cats and flanges
But after installation I took it for a spin it was pretty bloody shakey
Get a strong vibration which varies through different rev ranges
So I've got all the mounts attached welded up a mount for the second mufflers on the car back which mimics the positions of the original
Only one I haven't got attached is where trans is as I was told it wasn't necessary but I think I might get a bar welded between both cats pipes to utilise that mount
The original system was the single cat system like most series I but my SII was build late 03 just before the new EPA laws got implemented and Holden changed the systems to dual cats to comply with new standards
Any advice would be bloody awesome
