R36 Deleting the exhaust drone accomplished!

[3C4M Guy]

This is excellent information Mr R36. Thank you. The exhaust business recommendation is particularly useful to me because I'm in Melbourne. I have a 3.2L V6 but the info is useful all the same. I test drove an R36 once and I noted the exhaust drone at idle was a sort of buffeting that was quite headache-producing. I couldn't have lived with it and I assumed that R36 had been 'fiddled-with', but perhaps they are all like this. Anyway, you seem to have accomplished a good fix.

Hey mr r36..do you have any pictures of your setup?

drone on normal R36? never heard of it

Pics please!

Video of sound please!

Unfortunately in Sydney so cant make it to Prahan and see the same guys, hence keen to see what the set up looks like and if someone here can replicate it

Im sure if you spoke to Hitech Mufflers they could do it or have done the same previously

I think I know what he means. My car does that, but only when cold and the car revs a little higher on idle, it stops itself very quickly once it starts to get up to temp.

Replacing the cats and doing the J pipe is interesting indeed. I assume the bulk of the $1100 cost is the cats themselves right? I should look into this, I ran into a similar boat, want an Arqray system but they're $3k+ which is a bit high for a steel catback just for noise. Supersprint obviously even worse. (And ugly oval tips...)
Innotech is the best easily but the price they are charging is literally hilarious, it is so bad.

[Mr R36]

Thanks guys glad to help solve this infamous problem!

How do i post vids? Unfortunately i dont have a before sound inside the cabin but I'm sure you all know what it sounds like. I can post vids up asap (Maybe youtube)

Re idle drone: hmm i didnt experience this with a stock exhaust. It has some deepness to it but i like that. I just didn't like that annoying low frequency drone while cruising around 2200-3200 rpm urgh.

Yes the cats are the expensive part but honestly i think it's pretty cheap overall because there are two cats needing change and phantom plugs so the o2 light doesn't come on. Add that with labour it works out well. also cat is probably the only part of the exhaust that will change performance as the system is straight through. So by increasing flow i can only imagine power has increased, even marginally.

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?

[Mr R36]

I can get some pics up next time I'm at the exhaust shop. I'm toying now with the idea of a remus muffler + valve control. now that I've got the type of noise in check , my next step is getting it more grunt and louder but it must be controllable so i don't sound like a hoon 24/7...only 22/7 (jk)

P.s does anybody know where i can get an air intake? preferably gruppem but the rarity and cost is almost pushing me towards forge motorsport.

[Jakeys]

Just be careful with the Gruppe M, it fits fine and is fully functional but because it was designed specifically for the R32, it curves away from the front of the car a bit too much and leaves a gap. It is purely aesthetic, up to you if this is a problem or not given the money you're paying. It's easily the nicest intake other than maybe the Volkswagen Racing ones (Which I don't think exist for the R36, happy to be proven wrong here) but it's not a perfect fit for the R36.

Other options that I know of are the Forge and the EVO-MS which is what I have. It just comes down to budget and what you want it to look like in the bay I think, performance and sound differences will be negligible.
