This isn't a G sedan but the same cat back is available. Invidia true dual exhaust. Kinetix cats and Tomei headers but it won't sound much different with just the cat back, just not as deep. It's punchy without being obnoxious and retains a resemblance of the unique stock exhaust tone.

 

Even the newest 1st gen cars are now 12 years old. Not enough people modding them to restart manufacturing of parts once their current stock is depleted I guess.

 

I have a 2006 G35 sedan that's an Auto and I replaced the stock midpipe with the Walker Midpipe resonator. The sound is absolutely perfect. I wanted some thing more throaty and slightly deeper but I didn't want any drone or have it be too loud/obnoxious.

I gotta say it's the perfect upgrade. I highly recommend it.

 

Anyone have an ISR single on a sedan? I like the sound and wanna get it on mine

 

I cant seem to find it but i was looking at isr long tube headers. I have an 05g35x and read the longtubes dont fit. Which part of it doesnt make it fit if anyone knows.

 

Looking for help or information about the cat delete, O2 fixes and the right straight pipe from manifold to res setup
