G37x sedan Muffler delete

So I know a lot of guys frown upon the muffler delete but I removed my mufflers to see how it sounds and I love it. So my next step is to have straight pipes with tips made and my question is what size pipes should I use? Should I continue with the 1.75" pipe that went into the muffler or can I go with 2" instead or do you think it would create drone if I went up in size .25"?

Straight pipe will be raspy and the drone will be there. I would stick with 1.75

Where did you get 1.75 inches from? That's smaller than the factory piping.
The OE pipe diameter is 2.25 inches.

I did 2.5" dual after a Magnaflow x pipe resonator. I love the sound.

I measured the pipe after the resonator where it connects to the exhaust and the OD is 1.75

The diameter after the cats is 2.5. Why would you want to go smaller? Replace the resonator as well.

All I'm looking to do is remove the stock mufflers and put pipe there so there's exhaust tips.

That's what I was going to ask you too because I want to see if there's rasp and what not, I live far but can make sometime one of these days out there to check it out, how much did the whole set up cost you?

Here's the full pic:



OEM cat-back, with custom Magnaflow tips. The OEM Sedan exhaust pipes are 2.25"-ish.

I discarded it. Actually, I left it in the shop, and last time I was there they had it hanging in the rafters as some weird kind of decoration.

I couldn't do that.
I always keep the factory parts so I can put them back on if I sell the car and then sell the used parts.
