New Exhaust


Recommended Posts

Fit like loons?

Well been traveling a fair bit in the 330s now, but i'm not getting that AWESOME subaru rumble of old :angry: Any of you out there know of something that can up my volume? I'd like to keep the quad pipe as it looks mean.The best I got so far is this from cobra http://www.demon-tweeks.co.uk/performance/exhaust-systems/car/subaru/impreza-07-on-ge-sti/2009/2-5-turbo/cobra-sport-3-turbo-back-exhaust-system-with-de-cat-non-resonated--3-5-slashcut-angled-tailpipes

Also will i need to get it re mapped once i get a new exhaust fitted?

I have a hatchback STI, not the 330s but much the same. 

Like you i was not getting the scooby noise i wanted, so changed to a cobra exhaust. I went for the resonated cat back one, as i didn't want it too loud.

It definitely ups the volume, but i don't think it makes it sound like the proper scooby burble i'd have loved to have. More like just a sportier car, if that makes sense.

Maybe as mentioned earlier, the hatches manifold layout just hides the sound we are obviously both after !!

you need to change to unequal lengh manifold for a rumble,when i fitted the quad pipes to my wrx hatch with none res centre section it did not really make a diffrence to what i could hear in the car but every one out side said it sounded nice,guess sound proofing in the hatch is good as well,i was going to swap back to a single pipe with 4 inch exit to try make it a bit louder,still wouldnt have rumbled but i sold car so never got that far into my experiments with it.i was told scoobie clinic do a good manifold.

I'd also consider looking at Hayward and Scott exhausts as on my previous Classic Prodrive they have really given the classic Scooby sound. Been a long time since I fitted one so not sure on their quality now was very very good quite a number of years ago. Might also not make any difference if you have equal length manifold.
