which 1 is better and which 1 is louder?

they are both practically for noice only. you wil not see much of a increase in power. if you want a good sounding exhaust with power, i would look in to a draxas full exhaust www.draxas.com

Is 725 worth it for a draxas? I cant imagine big enuff gains for that type of money.

there is currently a $75 off deal going on, and yes, a 2.5" stainless steel mentrel bent, high flow cat with s-pipe and a lifetime warranty... indeed it is

what about the GReddy ones? there are not for sound only. Of course, they are not going to gain #s as a complete cat back exhaust like the draxas have, but they show some #s and their sounds are awesome...

90% of the comments about the sound only is bs. The power comes from the header/S-pipe/and removing the cat on the second mid pipe ( ie what most aftermarket cat back do ). Your factory pipe is stainless 2.25" and unless you plan on 300 hp it is plenty. I put 160 foot pounds of torq. to the ground with a "sounds pretty" TRD exhaust....also the TRD with resonators sounds the least rice of them all with a header.

draxas??? i raced a tc with it and ugh sounded awful... maybe its just me but it was terrible... and now i read that its over $700????!?!?!?1 thats a joke
