its a really distinct difference, the boost is smoother and you don't have the low end lag (or most of it) like the stock levels. And more tq than hp makes me happy,heheh.
Stg1 = bone stock Cost nothing, other than the AP stg2 = TBE (Turbo back exhaust) Cost between $800-$1200 + AP
You would only want an uppipe if you have a '05 or earlier model. If you're on a budget, all stage two requires is an aftermarket downpipe, which can be had at around $250-300 for catless.
No, but it's highly recommended. FYI, I went stage II for $125 for the TBE and reflash. $200 if you include the Prodrive uppipe, and that includes installation for both.
I still have my stocker sitting in a shed that I need to sell, so my grand total will go back down once that's gone
then you risk leaving a piece of cat in there and boom, turbo goes bye-bye, not worth the risk in my opinion. Get an ezr off ebay for $60 and call it good, you'll have to take the dp off anyways to get the uppipe on there so why not do it all at once?
i just went cobb stage 2. here is what i have: stromung ceramic coated downpipe crucial uppipe bosal twin tip catback stage 2 91 oct map it took me 3 years to get to this point, but i figured i've spent ~$1800 in upgrades.
<---- Cobb Stage II as well... :biggrin: - Catless Invidia UP/DP (found combo pack for about $400 new!) - SPT Cat-back (I just got this and LOVE it!) (picked up used from Nuke's buddy for $300 used!) Better air flow, 500 RPM or so sooner boost than before with catless up-pipe, smooth throughout, and feel very little lag under w00t keeping RPM's high!!! I love it!!!
