Exhaust G37X sedan



This is where I took the Y pipe out and did the true dual. Do any of you guys think that the true dual would give it a different tone? It just doesnít sound like it has the VQ tone anymore
Hey guys Iím sorta if New to this and I know there is probably a bunch of other exhaust threads but I wasnít sure how to find them. I just had a question about my exhaust, I have a 2011 g37x sedan with a muffler delete and kinetix HFC. As well as I got rid of my Y pipe right before my cats and did a true dual. I love the volume of the exhaust and how loud it is but I feel like I got a different tone doing the true dual, could that maybe be why? Itís not from the HFC because it sounded like this before I put them in. Let me know what you guys think! Thanks. *edit to this I got rid of the little y pipe after the resantors. Iíll provide a picture of what Iím talking about

Cross-over/X makes a difference on sound. Removing that single-pipe section is why you lost that exhaust note.

Yes. I looked yesterday but couldn't find a Garage Masters (Motor Trend channel) dyno comparison of dual pipes, dual pipes with cross-over (H-pipe) and X-pipe. No power change but small torque improvement in the mid-range and definite change in tone with the X-pipe having the most liked sound.

Wow, I really appericiate the help! Definitely will be posting more on the forums. I will try and go to my exhaust shop Friday and get an X pipe but just to 100% make sure I know what youíre talking about , I would get rid of the true dual and replace where that is with an X pipe to most likely get the sound Iím looking for?

Talk your shop about price between a H-pipe and an X-pipe before you spend money.

So I figured out i already do have an H pipe but still with the dual? What would be causing this tone Iím getting? Still think an X pipe would give me the tone Iím looking for?

So again any ideas at this point to try and find that tone Iím looking for? So clearly if I have an H pipe the next thing would try an X pipe??

Frankly, I'd recommend ditching what you have and buying a cat-back. It'll be 304 stainless steel versus the mild-steel you have, there'll be no crushed bends, it'll have a cross-over or X-pipe designed in, constant diameter from cat to muffler, and everything fits and you'll get your VQ sound back. Not to mention it'll bolt together for ease of maintenance, like when you need to replace the diff bushing...

I don't know your financial situation but I feel doing anything more to your current system is throwing good money after bad.

I defiantly have thought about ditching it and buying a catback, again I really appreciate the help. Money isnít too big of an issue but if Iím gettin a catback will mean Iíll have mufflers so what is a pretty loud catback thatís pretty good priced again money isnít a huge issue but it wouldnít be bad to find something reasonable.

This is good advice
