trel Posted June 22, 2009 Share Posted June 22, 2009 Car is running rich on WOT. Raw fuel flowing through the exhaust as you have a decat pipe. Burns as it comes out.

blind_elk Posted June 22, 2009 Share Posted June 22, 2009 I would be looking into the possibility of a collapsed cannon internals.

TiTAN Posted June 23, 2009 Share Posted June 23, 2009 you fix that issue by installing a cat and having that burn up most of the fuel.

De-cat pipe> high flow cat> regular cat> gutted cat when horspower is the determining factor.

GT-RZ Posted June 23, 2009 Share Posted June 23, 2009 fine in SA is a max of 10k. but they can only test you if you go for an inspection. the cops cant look under and assume because they cant see it then it's not there. only EPA can fine you and they must perform emissions testing to prove. plus if ur silly enough to go for an inspection without a cat then u deserve a fine...

Yet in NSW the EPA does random road side inspections... And they will slap you with a 10K fine in NSW if found on the road like it.

funkymonkey Posted June 23, 2009 Share Posted June 23, 2009 some cannons have materials in there for sound dampening etc, if its getting too hot, then they could catch fire and this could be the ashes you see.

TiTAN Posted June 24, 2009 Share Posted June 24, 2009 depending on heat you could also be melting the rear bar etc. Link to comment https://www.sau.com.au/forums/topic/275968-exhaust-cannon-glowing-red-with-ashes-coming-out/#findComment-4676125 Share on other sites More sharing options...
DaGr81 Posted June 24, 2009 Share Posted June 24, 2009 What happens if you don't stop for the EPA? Put a cat back in and retune it, use the Decat on the track Link to comment https://www.sau.com.au/forums/topic/275968-exhaust-cannon-glowing-red-with-ashes-coming-out/#findComment-4676248 Share on other sites More sharing options...
Pattygtst Posted June 24, 2009 Share Posted June 24, 2009 just get a retune, keep the decat& check exhaust for faults ignore the fine comments. That will never happen.
