    a couple exhaust questions for you guys!

    hey guys i just got an 06 wrx and i love it its an amazing car!! but i would like to put an exhaust on it and go stage 2 so i was thinking about gettin a turbo back b/c i read on cobbs website that u need a turbo back for stage 2 and u also get added gains but i read on here that you can also go stage 2 with a downpipe and a catback id really like the sound of a catback with the performance of stage 2 but what about those extra gains from the turbo back? whats the difference between the two? will i still get the same stage2 output with a dp and a catback as i would with a full turboback system? thanks guys!

    ps. does anyone know where i can get the "sti genome exhaust"(like the one in the exhaust video clip thread) or just an sti exhaust if it will fit on the wrx?

    Turboback = downpipe + catback

    To be stage 2, you really just need an aftermarket downpipe, though most people replace the whole thing. A budget setup would be something like an HKS downpipe and the stock catback.

    I would also be interested in an STI Genome exhaust. I love the way it sounds in the clips that I've heard, but I've never seen one for sale anywhere.

    it tappers to 2.5 to fit stock dp, its the same as the SPt with a can style muffler on the end.

    You can, you just need the dp to tapper to 2.5in. cobbs dp does that.

    you should get the SR*S full catback exhaust + SR*S bell mouth downpipe

    you should get the SR*S full catback exhaust + SR*S bell mouth downpipe ,with no taper down ,all the way 3 inches ,here is the link to the review and sound clips::

    SR*S Catback Exhaust from EBAY PICS and VIDS

    that seems like an amazing exhaust thank you for the suggestion! can u tell me a few things though? if i get the dp first will it bolt up to the stock cat back exhaust? i want a dp w/ a high flow cat does the srs have that? if it doesn't what is a good dp i could get that would fit with the srs catback that does have a high flow cat? in this link on ebay does what pipes does this come with im no exhaust expert lol

    SR*S doesn't make downpipe with high-flow cat ,because those high flow cat downpipe are useless and pointless ,they are not the actual cat-converter ,they are just a resonator and claim they are high flow cat ,so srs only make downpipe with cat-less , the link u show comes with a full catback exhaust only because catback means from the cat to the back, ,if you want a downpipe ,here is the link for it:

    http://cgi.ebay.com/ebaymotors/SR-S-...QQcmdZViewItem

    this downpipe is cat-less ,straight through with 4 inches bell mouth open and 3 inches pipe ,this downpipe will direct bolt on to your turbo and then bolt on to the catback exhaust ,then you will have a full turbo back with no restriction and get all the power you can get from your engine.

    and also there is no reason for you to use a 2.5" taper down exhaust when you are doing turbo back , the only situation you will need those 2.5" taper down exhaust is when you planing to keep your down pipe stock forever on your car ,because the purpose of using a taper down exhaust is to bolt on to stock down pipe with no air leak out ,so if you planing to do turbo back ,the SR*S Full catback exhaust and the SR*S bell mouth down pipe would be your best choice ,because they are all the way 3 inches with no taper down on any portion of the exhaust and down pipe.
