Exhaust Upgrade Without the Noise

Hey Guys,

I'm looking to upgrade my full exhaust system but I want it close to stock as possible. I'm running a non-turbo setup for now.

So far I'm planning to purchase Megan Headers and some High Flow Cats (Not Interested in Test Pipes, because I've heard a few, and they all sound horrible)

But heres where I'm having a hard time deciding. Theres a H Pipe, R Pipe, X Pipe and Y Pipe Setup. Which would you guys recommend for a quiet setup because I know the HP difference between the 4 are not that significant.

Also what mufflers would you recommend for this setup.

Came across a Local G yesterday that had exactly what I was looking for. Hes running:
1. Stock Headers
2. Ebay Catalytic Converters (Not High Flow Cats)
3. Ebay Factory Replacement Y Pipe
4. Magnaflow Resonator
5. Magnaflow Direct Bolt on Muffler

Not sure how quiet you can make it after you add headers. But for a cat back resonator the Vibrant Ultra Quiet works. A resonated Y-pipe can also help keep down the volume. Circuit Werks and Motordyne both make them. Dynomax and Magnaflow have quieter performance muffler options. Walker Quiet Flow mufflers are pretty good as well.

Cool Thanks Bro. I think i'm going to skip on the headers. I've also seen alot of good reviews for Vibrant Ultra Quiet resonators, so I'll definitley try it out.
