R36 Deleting the exhaust drone accomplished!

[Mr R36]

You have both a forge and evoms? Are you willing to sell the forge? I'm giving up on ghr GruppeM due to rarity and exactly what you said - purely aesthetics and costly

[Jakeys]

No I just have the EVO-MS. Sorry if I wasn't clear with the post.

I haven't noticed any drone in my R36. I've always wanted it to sound better, though, but I haven't done anything about that problem in seven years. If I weren't toying with the idea of selling the car I'd be all over a more ridiculous sound, but... hm. Decision.

Youtube sounds good!

Aiming to go the non-cat replacement route to save some $$

MrR36 can you provide more pics or info of the J tube lengths and position where they are resting?

I think I'm asking the same question as Danny here, MrR36. Would it be worthwhile to remove the suitcase and replace with the J-pipe if you aren't replacing the cats?

Would you effectively get the suitcase delete sound without drone between 2k-3k rpm?

Apologies if I am repeating Danny's question.

Thanks in advance,
Damo

Keen to know the answer =)

Damo, potentially we can get a group buy happening haha

Let's turn to logic...and opinion lol. Depending on how long you plan to keep the car for, anything over 2 years I would do minor mods because:

1.The car will continue to depreciate regardless of mods

2. Mods in my opinion will not change the value of the car to the prospective buyer based on:
- pricing of the car at the time of sale (anywhere from 16-25k in 2 years time) will attract a different customer demographic compared to brand new buyers
- empirical evidence: everyone on this forum owning an R36 wants to change the sound anyway

3. reward versus cost: from 300 - $2400 (intake, cat, tune) extra in total over two years you're essentially paying $2400 (dw about discounted cash) or $25/week for more out of your car. How much do you value driving experience? Imagine buying the R36 brand new again and that feel.

In my opinion for a small price to pay for little risk, I'm getting a better car and better everyday driving experience.

- pitch over haha

Re J pipe: I don't know as I'm no expert but what I was told and have read suggests that the J Pipe alone decreases drone and increases rasp due to the pulsing inside the chamber. I can only imagine that the difference in gaining rasp is marginal compared to decreasing drone. High flow cats will change the tone of the exhaust -definitely more tinny and raspy but its the rear muffler that will largely determine noise level

If you're all in Melbourne and want a group order I'm sure the muffler man will work up a deal. From what I've been told though they don't make much money from customising the J pipes but they do want to work more with the vee dubs so i think it's an area worth exploring.

Hey guys I'm trying to upload on YouTube but it says upload suspended 0%. any idea why?

I've uploaded once before.the only difference is that it was private and not public sharing.

[Jakeys]

I'm in Adelaide so I can't partake as it would be pointless shipping me anything as it is not bolt on. I'd like some pics and/or dimensions though so I can take something to show a local exhaust shop as I think you might have come up with quite a good idea here. The only thing stopping me doing suitcase delete is the drone reports, if this fixes that, I'm interested, because it's about $3000 for an Arqray catback, or it sounds like you could do this with the high flow cats for under half the price. And I might even just do it and keep stock cats for even less, I'm not looking for crazy loud, I just want that awesome crackle.

(No idea on Youtube btw.)

[Mr R36]

Update: I can't believe it but I've managed to get even more crackle, rasp and less drone. It's more noticeable in cabin now and all other features such as drone during cruise and idle noise remains in all fairness unchanged. I suspect however that cold start will be louder as per priming of exhaust but that will subside in about a minute.

How did i achieve this?

I deleted one hot dog resonator (right before the cat) and replaced with straight pipe. The muffler man suggested i don't do both hot dogs to begin with. One deleted also creates an uneven note which further adds to the crackle. I also have pictures which I'll now learn to upload
