Currently my mods are: depo intercooler, aem dryflow filter, and tune. How can I get more power? Is there a down pipe that would bolt to the stock exhaust and give me more power while keeping the car quiet?
Get a big turbo and a downpipe. The Mountune MRX kit and it's corresponding downpipe would be all you need to make more than enough power. Don't worry about upgrading the stock catback.
Atp turbo kits will bolt up to stock downpipe though it is not recommended. Atp gt2860rs kit can be had for a decent price. You will need a blow off valve.
Yeah get a catless DP mated to the stock exhaust. Personally you'll be able to tell there is a different sound note. But anyone else will think its stock.
And dem turbo whistle noise when the windows are down. Hhhhnnnnnnnngggggg.
The stock catback isn't a terribly restrictive exhaust. You'll be fine with it.
you do NOT need cat back for Stage 3.... and stage 3 is what I most consider the most power for the stock exhaust. The stock exhaust is plenty quiet aka silent.
