Exhaust Drone - How To Reduce It

[wanted r34gtr]

which resonator should i use ?

I was told by the exhaust shop that the spiral hotdogs woudn't reduce flow but i find it hard to believe. Hence I fitted a perforated hotdog (so i wouldn't loose any power through restriction) but the drone is still there !

Has anyone used a spiral hotdog and noticed any restriction .

The only other solution is to get a new rear muffler as the system i've got is a 3inch straight through, with a cannon and 5 inch tip

forgot to add that i don't want adjustable or removable silencers .

thanks in advance for any help

regards

You can buy cannons with removable silencers. Good for when you cop a canary..........

Has anyone used a spiral hotdog ? does it reduce the exhaust flow ? the perforated hotdog is not enough to eliminate the drone .

I've been told the other option is to get a oval muffler as opposed to a cannon .

Anyone else with ideas ?

Hotdogs do not work.

There have been plenty of topics on this over the years.

The only TRUE fix is a dual muffler set-up, of decent quality.

You only have one cannon, and a 5" tip.

Two mufflers and a 3" tip will fix your problem. Its not the cheap solution (hotdogs are far cheaper) however its the only one that will work.

what canon/muffler do you have?

if you want quiet, get a jasma jap branded one.

i changed from my semi titanium reinhard to a HKS super drager & its quiet as!

try hks silent power as well for quietness.

sounds like resonance might be more of an issue than the exhaust note itself

i'm guessing you've got a reasonable sized exhaust thats only very thin walled?
