Scored a set of stock pipes and headpipe for my '14 SG. Plan on drilling out a 1/2" hole in the baffles (want a little more sound).I hear that it's not necessary to re-tune (remap). Is this true??
Next step is gut the cat.. Gonna try it to see how it goes. Worst case, I'll sell the modified parts.

 

For what you are doing, a tune is not necessary.

 

Gut the cat and you will be tuning.

 

never heard of anyone being excited over a stock exhaust lol

 

Excited???
