Stock tailpiping for dual duals?
 

I'm planning to put a dynomax super turbo on a 2001 V6 camaro convertible with the SLP dual dual tips. I'm missing the tailpiping. Approximately how long should it be? I want it pretty visible or at least like the stock length on a SS. Or should I just go to the muffler shop and see what they got? Thanks

OK, now i have another question. My stock setup is the single outlet muffler. I would need an additional hanger for the second pipe on my new setup correct? I assume the muffler shop would drill in the right place, but is there any parts I should warn them about? Thanks.
