The most popular Y pipes are the OEM HR Y pipe from an 07+ 350z or the M2 Y pipe. Both will fit

Ok but the strange thing is when I do a search and look at the details it saids 3" for the M2 or do they sell them with different outlet diameters? Sorry for my nubness just wana do it rite the first go around.

Unless you're an "X", it will fit

Z-Tube, K&N, Plenum Spacer, Coupe Midpipe, Stock 03 Muffler with Fatboy Tips. Right before the HR Y-Pipe installation. Couldn't embed the videos for some reason.

someone had a white sedan with a single tip magnaflow. Who was that?

^G35Papa

i have a rwd sedan and need help i did a ghetto cat delete mod by cutting them out and just welding piping in place and didnt know it would sound so horrible so now to fix i plan on getting the megan racing resonated test pipes and the m2 HR y pipe and keep my stock mid pipe and muffler cause im saving for the tanabe medalion. Would these work with my stock midpipe and muffler and would they work when i get the tanabe in the future?

^yes they would work

made this quick video tonight, my 7 year old son and I were waiting for his little brothers to put their shoes on and he asked me if he could rev it lol i would have made it longer but i was standing in the middle of the street and a car was coming

I just added the Borla cat back system to my 03 sedan. I love it. It's not too loud but it opens up when you hit higher rpms. Gives a nice slight tone when driving normal as well.

Yours is full MD right? Even ART's? Sounds so damn good.

Here's my all MD exhaust with ARTs.

I'm in the process of adding headers to my setup so hopefully I'll have some videos up soon

Does anyone know the part # for the magnaflow resonator (pre-muffler) from the list on the first page?

06 Sedan - OEM resonator removed - Magnaflow pre-muffler installed

The resonator was removed by the first owner of my 06 g35x and I have been looking into finding a cheap way to make it sound better. If someone could give me a part # or point me in the right direction.

Thanks

Any of the smaller "glasspack" type or straight through race-mufflers will work. Since you have an 06 with the larger stock muffler, I would go with an 8-12 inch muffler. The guys with the smaller 03-04 mufflers run larger 14-18 inch resonators.
