    Hey guys. I've got a few questions. I've got an 03 SRT4 with these mods (that I know of): Mishimo radiator, AEM CAI, BOV, and exhaust. I just bought it and those are the only things I know for sure. I've never had a turbo'd car or a 4 banger. V8's and supercharged are where my little knowledge is. So here's the questions.
    1. What's the best sounding exhaust (deep sound). I've heard some SRT's sound like some damn V8's. Impressed me.
    2. What are some good mods to start out with? Plan on running on the stock turbo and see what I can get out of it. So keep that in mind.
    3. What mods are typical that I may have missed that I can look for? Since I don't know too much about 4 bangers or turbos at that.
    4. Any other tips, tricks, advice, or anything about these little cars would be helpful.

    Thanks in advance.

    congrats on the purchase.

    the best sounding exhaust IMO and also the cheapest is 3" straight pipe its also the lest restrictive besides Needswings race dump downpipe. but the thing you want to look at in your current exhaust if make sure its mandrel bent and not crush bend for best flow.

    stock turbo runs out of efficiency at 21psi. HP/TQ cross at 5200.

    first thing i would do is boost leak test the car and there is a how to on that.
    add a check valve and catch can which you'll probably do on your boost leak test.

    second thing is buy a Wide band O2 and DS Pred since you'll be playing with boost.

    Motor mounts help alot with traction and the inserts work just fine. the rubber bushings on the car if still stock will be pretty tore up so upgrade to poly everything. HAWK HPS or HP+ will stop you nice and hard. spark plugs NGK 4306 and gap around 30-33 or play around and see what the car likes everyone is different. my PT/GT liked 32 and my neon likes 30.

    and last browse though the threads for other ideas on what to do and enjoy the car.
