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 doesn’t sound like it has the VQ tone anymore
Hey guys I’m sorta if New to this and I know there is probably a bunch of other exhaust threads but I wasn’t 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? It’s 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. I’ll provide a picture of what I’m talking about

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

so you recommend an X pipe to get that tone back? Or how would I get that tone back from where I’m at right now

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 you’re 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 I’m looking for?

Well that doesn’t help me 😅

So again any ideas at this point to try and find that tone I’m 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 isn’t too big of an issue but if I’m gettin a catback will mean I’ll have mufflers so what is a pretty loud catback that’s pretty good priced again money isn’t a huge issue but it wouldn’t be bad to find something reasonable.

I have it narrowed down to Stillen or fast intentions. I’m a little curious to weather I’m going to pick non reasoned , 12” or 18”.... any suggestions
