Hi - sorry if this is not the correct forum, but I just signed up and couldn't find a better one.

I recently got a Turbo XS ECU and and up-pipe installed in my 2003 WRX wagon - it seems better, but now I want to go a bit faster. From what I've heard/read, the next thing to do is to replace the exhaust system - any ideas?

My main consideration is of course, lots more power - but I rather like the stealth aspect of the car, and would love to keep it REASONABLY quiet.

Any comments/suggestions greatly appreciated...Chris

 

Turbo should be last on the list. Getting a bigger turbo just entails tons of other stuff like fuel management. I would go with a downpipe and an exhaust. The scooby sports sounds pretty low key until you really jump on it. I would save a bigger turbo for later, because you are going to run into detonation problems unless you have good fuel management and good engine management(do you know how to tune your UTEC?). I would just work on freeing up your exhaust.

Hi guys and thanks for your perspectives.
Do you have any ideas of specific manufacturers, models, etc, for downpipes and exhausts?

Much Appreciated...Chris

 

I think the perrin dp is nice because of the divorced wastegate dump. If you get one that just has a wall where the wastegate dumps to you create massive flow restrictions where the wastegate gasses have to merge with the exhaust gasses. There are a few other companies that make divorced wastegate dumps but I can't think of them off the top of my head. If you wanna keep it quiet I would probably consider the scooby sport, I also head that the cobb exhaust was pretty quiet until you get on the gas. If you want a bigger, better flowing, exhaust then you will have more noise when you get on the gas, but you can always look for an exhaust with silencers, but again that creates a hinderence for the exhaust gas. But it is all up to you in the end, I would just go to a suby meeting in your area and see if there are any exhaust sounds you like.
