very nice job.

a couple questions:

what would the cost be if it was a direct bolt on without using "any" components from the oem/factory exhaust? to become an easy swap out.

i would want to retain the "complete" factory system... so i could remove your system down the road and re-install the oem muffler again at resale, trade in, etc.

also... will tips (borla, etc) bolt on to your muffler system if desired?

thanks!
