I don't believe I have an X-Pipe in my exhaust, unless you are referring to the merge collector behind the secondary cats. Like I said before though, the quad/dual exhaust (like you have) changes the tone immensely. I have heard a few videos of those types of setups and it sounds nothing like what I am experiencing.

No difference. Deleting the secondary cats only adds some volume to the exhaust note.

My exhaust is entirely stock. All I have done is cut the secondary cats out for straight pipes, and then cut the resonator out for a straight pipe. Since i've cut the resonator out I have had raspiness and drone.

Magnaflow Glasspack installed in lieu of the resonator. Sound is amazing. No raspiness or drone. The tone is very deep and throaty...exactly what I was looking for.
Have a hear for yourself and compare to the sound in my other videos.
I purchased the glasspack from Summit Racing in Southern California for $45. Unlike the old glasspacks of the 60s, it does not use fiberglass and the acoustic packing material does not degrade over time so the sound stays consistent. Magnaflow offers a lifetime warranty on their products.

Bottom line: Do not delete the resonator for a straight pipe

Thanks guys
Just to recap: The entire process cost me $155.
Labor + piping for secondary cat delete - $60
Labor for resonator removal + glasspack install - $50
Magnaflow Glasspack - $45

I guess to each is own. I love love love my exhaust. It is loud but it sounds so good IMO of course.
Here is a sound clip for you to be the judge. This was done that day I got it and only at like half throttle around 3k RPM.
