Exhaust Cannon Glowing Red With Ashes Coming Out

[Chi100188]

Hey guys just wondering should i be worried over this thing? when in high rpm's and high speed my exhaust cannon goes cherry red and ashes sometimes come out of it? why does this happen? my car is a R33 GTST the exhaust is 3inch straight through with decat pipe

Cheers

Car is running rich on WOT. Raw fuel flowing through the exhaust as you have a decat pipe. Burns as it comes out.

[Chi100188]

oh true wat does WOT stand for?

[N1GTR]

Wide Open Throttle

oh ok hmmm how to fix this problem? lol should i just go for a retune or do i need a new exhaust lol

[blind_elk]

I would be looking into the possibility of a collapsed cannon internals.

you fix that issue by installing a cat and having that burn up most of the fuel.

save yourself a huge fine and damage to your car and fit a cat.

How much is the fine for not having a cat?

Most things I've seen say you actaully loose horespower doing that. De-cat pipe> high flow cat> regular cat> gutted cat when horspower is the determining factor.

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.

i k now about the fine but how would i damage my car?

[funkymonkey]

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]

depending on heat you could also be melting the rear bar etc.

What happens if you don't stop for the EPA?

Put a cat back in and retune it, use the Decat on the track

[Pattygtst]

just get a retune, keep the decat& check exhaust for faults

ignore the fine comments. That will never happen.
