Hey Folks,

I just had my HG fixed, and now I am thinking I may need to do the exhaust. Although they have nothing to do with each other, I started noticing a whistling at high RPM between 4000-5500 K noticed this before the HG issue.

mentioned it to my mechanic and he suggests that the ballast in the muffler are rotting out he has heard that it makes a whistling noise. He suggest drive it for a while then if it gets worse replace it.

Now I noticed a sulfur smell as I was driving home last night and thought it might be somebody else, but then driving into work today, the same smell came back, as I was doing 80Km.

Fuel economy on the car has not deviated at all, I am wondering if this is the signs the CAT is almost done ?

Any Idea's or suggestions ?

Part of me, wants to put on a really cool performance exhaust, but not sure I have the money for that right now.

Sulfur smell is usually indicative of you CatCon going out.

No Codes

The car is running pretty good, fuel economy is consistent at 24 Mpg.

I saw on boxer4racing that there is a cat designed for N.A Subaru's that is better performing than stock. Anyone have experience with them ?

Also if I do this, I may replace everything Catalytic on.

I was pretty sure, the smell was indicative of the Cat going :icon_frown:

So now to figure out exhaust, would like something custom but not willing to break the bank :icon_wink:

boxer4racing is great. Their prices are high, but their parts are high quality. They are based in my hometown, so maybe Im biased!

Sulfur smell is usually indicative of sulfur in the fuel of poor quality. Do not replace your cat., change your gas station instead.
