I currently have a N1 type exhaust with 2.5" piping for my car. Its kinda getting annoying since its so loud and deafening. I was wondering if i changed just the muffler(but kept the 2.5" piping) to stock or Spoon street muffler will it have an effect on noise reduction? and the main question is how much power will i lose throughout the power band(if any)?

the larger the muffler, the more noise reduction....similarly a longer resonator will reduce noise. As long as you choose a can without louvers for openings in the tubing within the can and avoid glasspacks (fiberglass melts overtime and loses it's sound absorbing efficiency) you will get a less loud exhaust. If you keep the tubing at 2.5 in. OD then you should be fine. The other option is to get a twin pass design can from Hytech instead of a straight thru design. The only time performance will be hurt is if you choose a chambered can or a smaller diameter inside the can.

Hahahah sorry about that i haven't read that article, i've only read your header article.
(Thats why i wasnt sure and did not post in the MD article forum)

I have a resonator already(not including the muffler itself) but its still loud. I just want to know wheter buying the spoon street muffler is worth it over stock. The spoon street muffler has an inlet of 60.5mm while the stock i believe is 2 1/4" will the power reduction be neglible?
