Change backbox on powerflow exhaust

[Dom]

Had a supersprint exhaust on my E36 318is and loved the sound, nice and deep but not intrusively loud.

I've got a powerflow on at the moment - if I changed the backbox to the supersprint do you think I'd replicate the same sound? Can't remember if I had a middle box on the E36 or not, definitely don't on the E30.

I'm guessing it'll be kinda permanent too as I doubt powerflow have put flanges in the original positions.

Any thoughts guys?

They should be able to make it quieter, which in turn should create a different noise..in theory

[Dom]

I don't trust my local powerflow though

The E36 manifolds were different plus the cat will make difference to the sound compared to your E30. Was it an M42 E36 up to 94/95ish or a late M44 1.9? All this will make a difference to the sound me thinks

[Dom]

Yeah, was the M42 but had a cat whereas the E30 doesn't. Cat rattled like a rattly thing anyway

[Simon13]

Best to take it to an exhaust place and get it on the ramps to see if the E36 one will fit, but i would have my doubts but i honestly don't know

Sorry getting mislead here I think. Am thinking of purchasing an E30 supersprint backbox

When i was looking for a new exhaust they looked at fitting a E36 one but said it wouldn't fit and they couldn't think of anything else so i just had a powerflow made instead. Told them to do it as quiet as possible and they did, sound pretty much the same as my standard one did.

Sorry
