What needs to be done...
because its titanium, the initial startup does sound a little hollow, but when it is warmed up, omg the sound is great, very tuned sound, loud...but you would never confuse it with the Camaro reving next to you. and it saves a crap load of weight vs the stock exhaust.
just my 2cents
for res/cat delete theres a couple options. I'm looking to do one myself and I am leaning towards doing a straight pipe for the cats and h pipe for the res to maintain the same path as the stock exhaust, just without the cats and res. my goal is to have loud but same sound as stock.
other option you could do is straight and x pipe for a smoother sound. from what i read straight pipes only wont be as good as you want the two exhaust pulses to cross in order to vacuum each other out.
IMO, there is currently no aftermarket muffler that I think sounds better than the stock, there for I wouldnt touch the aftermarket/valvetronic set ups.
