Exhaust to loud!

[GregNZ101]

I have a 3” exhaust on my wrx, but it is way too loud, unless the highly restrictive silencer is used. There is one small, and one large resonator leading to a straight through cannon exhaust.

I am thinking that I will need to change the rear muffler, to something like a flowmaster style.

So that do people think, will this make it quiet? Anything else to try?

Commodore/Ford V8 after market muffler...

Cheaper than other options!

The after market one is not that small, my one is a straight through 3" jobbie fills in the factory space real well

they guy i'm getting to make my new exhaust has a flowmaster copy on his 89 rs, said without any other resonators it was way too loud, he's now got a 15" resonator in the system and it sounds pretty mint

[Pappu1]

or swap with me...lol.. just the catback part anyway

3 inch with single resonator and strait thru cannon but is the proper muffler so sounds deep yet not loud

I have a 3 inch turbo back exhaust with three resonators and a Zerosports JASMA muffler. It's pretty quiet. Even with 2 resonators, it wasn't bad. So yeah, see if you can fit an extra resonator in there and change your muffler, should be plenty quiet.

[Stoffa]

If you havent worked it out Jasma isn't a brand its a specifcation that all japanese aftermarket exhaust systems have to meet (under 95Db I think).

They will usually have a plate welded to a jasma spec exhaust, if you find a jasma spec exhaust it will be legal in NZ, well usually, they're not allowed to remove cats in japan so a catless downpipe may make it a little louder than its spec.

The plate will also help you find out what brand an exhaust is, theres a few lists online, depending what numbers are on it they usually matched to a manufacturer.

This exhaust is actually a fujitsubo system, valued over $2000 normally, i've got two of them (one spare for full 3inch setup) my car passes wof's no problems with a catless downpipe

Fujitsubo exhausts are nice....

[subieboy]

This is fitted to a turbo's back 2 & 1/2 inch pipe into 2 & 1/2 inch joiner, into 4 inch flexi into 3 inch pipe all the way to the 4 inch tip...

Sound measured when made was below 95dB (if memory is correct it measured to 91dB)... cant get better than that for the whole system for $800 cash...

Actually you can get better than that, I got my second fujitsubo 3 inch stainless system for $200, a mate got the same thing but with a titainium muffler for $400.

I got a 2 1/2 inch system custom made for $350. so $800 is up there for a bitsa system

[bubblz]

u get that from here in wellys stoffa? from trademe or exhaust shop?

This was about 4 years ago that I got it. The system includes a cat as well:

 

turbo's back 2 & 1/2 inch pipe into 2 & 1/2 inch joiner, into 4 inch flexi into 3 inch pipe all the way to the 4 inch tip...

And its custom made to fit to the car (not some generic rubbish kit) I Have tried some of them in the past and they would have bits rubbing or hanging too low.

I got my exhaust noise & emission cert.'ed when I got the rest of the upgrades cert.'ed, this means that the WOF shop can't argue the point ;D

I got one off a local clubsub member, they pop up on trademe every now and then.

[GregNZ101]

Just had a Fujitsubu muffler fitted, very happy. Quiet when driving around normally and sounds great when I put my foot down, and a bit more power vs the old muffler with the silencer.

Only problem is it sticks out a bit

Well i dont think it will leave drity maks on my bumper ;D

[Simon C]

That looks really long! Was it designed for a GC8 or was it from a Forester or something? Mine stuck out that much when it was first fitted. If you can, get them to move it back a bit. Otherwise, you'll burn your ankles when you walk around the back to get something out of your boot!

[GregNZ101]

Its really big muffler so could not go any further back, it will do for now. Might try to change the tip later on

[funkytown]

llooks like the ones that go on GTB's, they have a long 4" section at the rear like that to get out past the bumper
