Quieter 3" exhaust - or swap for 2.75"?

[Ross]

I think enough people know about my project to know why I went from a 450hp engine back to ~300hp... anyway I've decided the exhaust needs to be changed. It sounds awesome, but it's too loud and the S2 is now as much a family car as a fun car, and if I justify keeping it now it needs to be suitable. Currently it's too loud.

I still want an element of performance, so I think 2.75" is the way to go. Recently went out in Sonic's coupe with full Miltek and it is perfect. Good sound, performance, and minimal boominess when cruising. I don't think trying to mod the 3" is an issue seeing as it's perfect for a high performance car so I think selling it, or at the dp-back section, is the best idea although if someone wanted to upgrade and had an ideal system then I swap is the best way forward.

So - any ideas? Anyone got experience in going from 3" to 2.75", or is it just the Miltek badge that seems to make it nice and quiet? Or more importantly anyone got one that they need to upgrade and want to make a trade? I'll put a for sale thread up if I end up having to go down that route, but looking at ideas first and possible swaps.

Is it 3" turbo back?

My 3"/2.5" hybrid is quieter than the Milltek for most situations and still makes a nice noise. Pop down if you want to have a listen some time.

Yeah it's 3" turbo-back, desgined for Garrett turbo but does fit a K24

Has a Borla back-box i think (could be magnaflow) and one of those tube-shaped silencers in between opposed to a fat mid-box.

all i can say is that i have custom made 2.75 and AAS exhaust specialists talked to about changing back to 3inch but quiet with an aim of 500+hp they told me that larger bore does not neceserally mean better perfomance and put me off into replacing the whole thing just now. SO 2.75 will be quieter than 3inch and it wont be bad for perfomance either

i have already tried milltek 3inch and BN pipes 2x60mm and both were much boomier than what i have now.

Thought you was sorting something with jamo? that would be a good option?

Ive got an S2 catback Milltek if that takes you fancy in some sort of swap?

Ill bid for that system if it's available.

You could weld one of those back box.
