|I'll be calling Delta to confirm, but...
The basic question: does the Delta performance exhaust system require using the 4 into 1 header? Or, will it work with the stock header and Y-pipe?
The DPO apparently just took Ms. Jenavieve to the local muffler shop at some point in the past and had them install a very basic system from the Y-pipe back... just a straight pipe back to a rear muffler (no resonator) with one exhaust tip. Doesn't look remotely stock, nor like the Delta system. It's noisy, and a bit leaky. I'd really prefer to not have to replace the header at this point though.
