Hmmm I think i've blown my backbox 😃
My exhaust system > astra z22se with standard exhaust manifold, pre-cat removed, standard cat, remus centre tube, standard non-irmscher back box.
Did have a remus powersound bb on but it was sooo loud and 'chavy' it really got on my nerves and did'nt want to pay vauxhall mega money for an irmscher so just got a standard 2.2 bb fitted.
This bb has been excellent, looked crap like a standard 1.6 from the back, but was really quiet and i think the car drove better with the added back pressure? notsure.gif
Anyway did an ecu reset the other day and been driving easy for a week or 2, but then gave her a real good blast down the dual. Errr no more quiet exhaust cryb.. not sure what happened, guess it got hot and fell to bits inside??
So Im looking for a new bb to flange mount to my remus pipe, it has got to be pretty quiet and subtle, like standard maybe a wee bit louder. Thinking about going custom and getting it well baffled.
What you guys running with similar setup?
