Titanium Exhaust Drone

[kaneryan]

hey guys

i got an r34 gtr

i just bought a trial titan tryforce 3' catback titanium.

i have a venom 4'' cat and trust front pipes

since fitting it last night, sounds amazing!!!

BUT!!!!!

has an awesome drone from 2700-3100rpm.

has anybody got a titaium exhaust and had the same issue?

its just got a resonator and a cannon muffler, ive heard the idea of stuffing your spare wheel cavity with sound deadening or blankets and stuff like that to stop the drone coming into the cabin, but didnt really work LOL!!

once again it sounds great but annoys me that inbetween those rpm's especially on the freeway when your cruising at 110 and it sits on 3000.

anybody got any suggestions

Single muffler - that is your problem. No single muffler Ti exhaust is gonna be quiet

Only way to fix it - add a decent middle muffler, or buy another exhaust.

[kaneryan]

okie dokie

any ideas on a decent muffler?

[kaneryan]

its not it being loud thats the problem, its the drone just around that rpm, do you think the extra muffler will make the exhaust tooo quiet.

cheers

I can use a stick welder and weld in a nice muffler in the middle. I'll use the oxy to cut the pipe too

[kaneryan]

^^^ done and done^^^^

can you guys recomend any nice mufflers?

does it have to be titanium to weld to titanium? or can it be anything.... i dont car as ive already saved myself like 10kg+ in weight anyway!

cheers

Step 1: sell the titanium exhaust and pocket HEAPS

Step 2: buy a quieter exhaust and have HEAPS of change

Please don't wreck the Ti exhaust by adding some botch job muffler onto it.. Not sure if you realised but DVS JEZ was joking. Stick welding and oxy cutting are probably the messiest way to do anything, and you probably couldn't even do it with titanium.

[R31Nismoid]

A decent muffler will weigh more than the entire exhaust TBH.

And of course it'll make it quiet.

If you still want "loud"-ish and less drone you need to sell the Ti system, you'll never achieve both as they always have wafer thin mufflers.

[kaneryan]

Well dont wanna sell it as I waited 3 months for this exhaust to arrive a month of that was with auspost so its kindof like ive been through all of that to now throw it away.... I dont think i can do that

[R31Nismoid]

Well I suggest you purchase a set of earmuffs

Turn the radio up Kane or stop being a pussy

exhaust wrap the pipe?

[Piggaz]

exhaust wrap the pipe?

How on earth would that help?

[GTR81]

Has your cat still got its insides intact? I've got a titanium exhaust on my car with only a single canon muffler and its pretty good

with a cat but drones like a mofo without the cat

[kaneryan]

Yeah cats brand new, and ive heard of the exhaust wrap working as it makes the exhaust thicker... Might try that next

[kaneryan]

doesn help when the cops pull you over and tell you its too loud either might have to fi this one sooner than i thought

Do what GTScotT said? I had to get rid of my Ti system, couldnt afford a Mine's VX Silence Ti (for the weight) so I got a stainless system, lost 80hp because I went smaller diameter.

But, for the money I sold the Ti system for, I bought the Stainless Fujitsubo, got the Ti removed, new exhaust fitted, dyno tune and pocketted a $150.

[kylieyeah]

Wait what... You lost 80hp!!!? I'm guessing you went from a 90mm to a 80mm and lost that much? Wow that's 60kw.

Very interested in power/exhaust size ratio. What were you making before you lost 80hp??

How on earth would that help?

noise not only exits the end of the exhaust pipe but also resonates thru the pipe itself, exhaust wrap would act as a silencer as well as keeping up exhaust gas velocity
