svt makes a little more power but the work and cost is not worth it in my opinion. i love my long tube and 2.5 in flex i got it all from ebay for 160 shipped it sounds good on my stock exhaust but if you have another exhaust it may be loud but an extra resonator will make it better
im putting the svt header on stock exhaust. so you can tell a differance in sound with the stock exhaust? cool, i was hopeing that it would be a little louder! still have to save up for my cat-back
Here is a link for a full set up from CFM I did the math and it is about the same price wise maybe a little bit less if you bought everything separate i did the math in my head so I cant say for sure.
