Hey,

Well I got a nice letter from the EPA the other day about my exhaust being too loud. When going for the test is it ok to have ANY exhaust system as long as it is under 90db? Are there any restrictions to what exhaust system you can have excluding the amount of db it produces?

Thanks

Providing the car is under 90db, you can have any exhaust, as long as it has a cat. Please keep in mind that if you put in a silencer at the end, it will be recorded that you run a silencer and you must keep it on at all times from then on.

Do what most people do, swap it for a stocker. A lot easier.

Im pretty sure they dont let you use a silencer at all unless it is fully welded in, look on the vicroads website, it covers everything in the modification guide. just do a search.

Any system is ok as long as it doesn't breach the 90db limit. But there are a couple of guidelines, i believe you are require to have a cat, and 2 mufflers, one under the car at the front and one at the rear. Be aware that epa and the police do use digital camera's now days to keep a record of ur shall we say our behaviour, i have recieved 2 fines at $511 dollars EACH. Having said this, on both occasions i was pulled over by a police officer who carried with him a portable db tester. For the record this was PETTET. lol. Swapping the rear muffler for a stocky just won't cut it no more. Sigh.

      What should I do next to hold the head on

      I can see between the water jacket and cyl 3 there wasn't a hard line of combustion gas. It certainly appears that the issue is coming from there. Yes, checked the tension. All at 100ft lbs where I set them 5 years ago. These blocks can crack but generally when they have been over bored. Mine is only 0.5mm oversize at 89.5mm. They break between cylinders around the 91mm mark. No sign of that with mine. My gut feeling is the head gasket lifted a while back when the studs stretched and i bandaided it by retorquing the studs. It's finally let go.

      So, version 4 intake is on its way I was looking at these a while ago but at around $200 or more it was a little pricey for something that might not work, but, I had it in my watch list, but, I got a message saying it was on special, and I had a code thingie to use, it eventually came in at $120 delivered, so BAM, BUY NOW.....LOL I'll need to have a look when it arrives but I feel it will "look" better than what I currently have, as it comes with a PCV fitting, so I will be able to get rid of the alloy pipe that goes to the throttle body with the PCV fitting  Well, that's what the voices in my head are telling me  Oh, and this happened today Yeap, it was a Trojan, and it was cheap, so I headed back to the hardware store and actually spent a little bit more on a heavy duty,  one that was actually recommended by a plumber mate, a Cyclone one with a fibreglass handle that is actually rated for clay The broken shovel will eventually be "modified" into a short handle shovel
