Or u can get a varex muffler with butterfly valve, so can control the volume with a touch of a button, and have minimal influence on performance.

Update from new owner: 375whp at 1.4bar on 98, at Tokyo Motorsport

I'd just look at replacing the rear mufflers, I've got a aftermarket DP and mid pipe on my Forester with stock rear mufflers and it's nice and quiet but I still get a slight gain with DP etc...

Same here ... After market DP ceramic coated and OEM exhaust after that. Performance gains and quiet operation.

My mate had his 2015 sti exhaust replaced at MM a few weeks ago, it might still be there...

Not meaning to sound blunt, but did you buy the car for yourself or for your neighbours?
I leave for work at 5am every morning and my neighbours can just deal with the car noise for all of the 10 secs it takes me to leave.
Never had a complaint from them, and I've even asked them about it.
I reckon you'll regret going back to stock.

Thanks mate, I'll see how I go with them tomorrow..

Would the new 2015 exhaust fit the outgoing model?

I'm pretty sure he said it was the same exhaust he bought for his previous 2012 wrx so should be

MM should know for sure anyhoo.

The 2015 exhaust is slightly longer. Will need the hangers adjusted and the factory length cut down with new flanges to fit.

Great stuff, thanks for the heads up guys.

Thanks guys for all of your help, I dropped in to Maximum yesterday, they plugged in the laptop and confirmed that they tuned the car with ecutek when they fitted the exhaust.

From what I can see, the exhaust that is fitted is just straight through with cat to a hot dog for each pipe at the back. Now that I know that it has been tuned, I won't be stuffing around with it just yet, I'll replace the cat back section later down the track (Thinking of going with Invidia) adding headers and Process West CAI at the same time then retune.

Thanks again for all the assistance, stock exhaust will no longer be required.. :-)
