When the OEM exhaust goes bad, then I put Duals on
I can't see cutting off a good exhaust just to make it duals but I'm older now You know older & wiser but when I was 18 I did take a new truck & put on headers & dual pipes-glasspacks but it also had dual straight bypass cut-outs & that's noisy.
stock exhaust for now but when it wears out gonna go with smog legal headers, straight to the back with glass pacs in the middle somewhere, I have found that if you put the glass packs about 4 feet from the end with straight pipe out just past the bumper, you get the best sound and it doesnt kill your ears when runnin
Ive got an aluminized Edelbrock RPM series cat-back dual kit, and a custom cat-forward kit, including Flowtech A/B headers, much more power, removed the catatlytic converter (lack of emissions inpesction) and it sounds throaty, but not obnoxious.
The aluminized pipe is nice because it resists rust, i would have gotten stainless, but it was too expensive.
I like to hear the plow scraping across the pavement and nothing else.
I dont feel I need to announce my presence at 3 am when I'm doing a residential driveway. I just spent a few bucks to quiet down my truck.
That's another good point. I turn the radio down and roll down the window so I can hear the salt coming out of the spreader. It never had a spreader, but if it had I'm not sure I could have heard it so well on that old GMC.
