if you want silent then OEM is your best bet. I love the stock DA exhaust personally.. i ran no cat w/ all stock set up on my 93 & it produced a beautiful tone. I believe mine may have been 2.5 piping actually, bottlenecking into the oem resonator & muffler.. bought it that way & never changed it. Definitely not the most performance oriented set up- but the sound was unmatched. It wasnt a pretty set up by any means, but crossover made heads turn
lots of fun. Both quiet in the cabin while cruising, not drawing any attention.. then throaty + mean after vtec.
tl;dr stick with stock if you want quiet. you can mod it a little to mess with sound, but if you want performance go with something else.
