Hello Justin... I remember from a previous post that from a GT muffler swap could increase HP from a V6. How much gain would that be? Would that gains bee from N/A of F/I? Thanks for the reply. :)

Thanks for the reply Justin. Could you direct me where to buy the muffler or if you have them in stock for purchase? Is it relatively easy to install? Do I need a tune to take advantage of this increased HP? Thanks.

We sell them for 125 shipped, or 615 shipped with a tuner and cai package. I have not added them to the site yet. It will take a about a week to ship out.

I was thinking of combining that with the LW I'm planning to purchase. I guess I could start with the Muffler then :) Is it a direct bolt on? No welding needed?

Cool!. Would probably wait for the Livewire then combine it with the muffler. no Need to be shipped though. Will probably pass by you shop like the last time I went to your place to get my X-cal2. A genuine pleasure doing business with you. By the way what would be the pick up price instead of the $ 125.00 shipped price you've quoted me. Thanks very much. :)

No, from a SINGLE GT muffler. We've tested it on two cars.
