Exhaust loudness dropped dramatically? - Toyota GR86, 86, FR-S and Subaru BRZ Forum & Owners Community

AZ_Racer_1 · 01-24-2015, 12:52 AM

So I have Borla exhaust and borla UEL headers on my FRS. I've had the exhaust for about 10 months and the headers about a month. It was decently loud after header install and good rumble but now all of a sudden it is like the headers aren't there.... It sounds really quiet barely can hear it while driving, unless in high Rpm's. It sounds similar to when I only had exhaust, little to no rumble. I don't have any loss in power just exhaust loudness? Please help

It's because you've gone deaf.

That is strange though, my experience has been that most exhausts get slightly louder over time.

Wow you are so funny dude....

AZ_Racer_1 · 01-24-2015, 02:07 AM

@Decay107 yeah that's what I thought, that's what happened with my exhaust, then I got the headers and it did the opposite lol

Was it a gradual drop or just one day was quieter?
Don't think it can be diagnosed over the internet but you have made me very curious.

Someone stuffed a potato in your tailpipe?

This is what I'm thinking. I can't imagine any other reasons for why a loud, modified exhaust would suddenly get noticeable quieter.

Your neighbors must not like your car very much OP.

Turn the engine on.

Check for blockage in the pipes. Seriously sounds like someone may have shoved a banana\malleable vegetable in to one of the tail pipes to muffle it.

Really? Stuck something in there? That's messed up haha but alright I'll take my exhaust a part and look through the pipes thanks for the suggestions! I'll let you guys know if I find anything

Oh actually I forgot about 2 weeks ago I got a bad batch of gas that reduced my power and then gradually reduced exhaust but I have refueled and cleaned the engine and fuel lines. The power is back but I'm thinking maybe there is still a little bad gas in there?

You probably are experiencing hearing loss due to your loud exhaust, or just becoming accustomed to it. Loud isn't loud if you are exposed to it daily.

I mean, it's happened before. it wouldn't get much past the actual muffler\tail pipe section, but I've seen it happen before - Friend of mine in HS had a stupid loud SLP Camaro, and someone managed to wedge an absolute ton of banana's in to his Bowtie-shaped exhaust pipes and it was both very quit, and very messy. Unsure if it actually did any damage.
