exhaust blowing sound..

[r8byb]

Hi guys, does anyone else get this running a de-cat and straight through system ?

Ive checked all the joints etc when cold and it's all fine no gaps but when driving it sounds like its blowing ?

Anything else it could be ?

Expanding when hot, causing a gap and blowing?

let the engine cool down,

start her up and put your hands over the tailpipes,

if it's blowing you will most definatly hear it.

you could get someone to help you, that's what i did, and mine was blowing!

Its probably the (de)cat to centre section joint on a 182, they're a b*****d to get to seal. Paste and a decent clamp are a necessity.
