Making my blow off or waste gate louder?

Making my blow off or waste gate louder without voiding the warranty?? Thanks

I grow weary of all these "I want to install non O.E. equipment that could potentially affect drivability, but still want warranty" threads.

Anyway here goes the info you seek. No real way to make it louder without voiding the warranty, atleast without going back to stock before going to the dealer.

According to some act that can be googled, the dealer must prove that an aftermarket part caused the problem to void the warranty. In reality they usually say you have to pay for an issue that may or may not be caused by your mod. Many times this happens if the mod you made COULD cause the issues you went in there for; lets say you went in for poor throttle response and have an aftermarket intake, they'll probably say "go back to stock and come back if the problem occurs with O.E.M. equipment." or "If you want THIS issue fixed you need to pay for it".



The most dealer friendly way is to cut a hole in the bottom of the airbox (the lower box that clips sits in the fender). This will make more noise, be virtually undetectable to the dealer, and if discovered the dealer won't void your powertrain warranty because of it.

Next up is an aftermarket intake. Even more noise and most dealers don't care if you have one installed. It's also easy to swap out if you have a dealer that frowns upon an intake.

Then there's the Forge BPV that replaces the stock unit BPV and functions the same. It's slightly louder than stock and fairly hidden thus hard for a tech to notice. If caught with it you may face some warranty concerns especially if you have turbo problems.

The loudest option is the Forge BOV. Like the forge BPV, this replaces the stock unit. Only instead of recirculating boosted air around the compressor, it vents it to the atmosphere for that loud pssshhttt sound. This requires a tune and will most certainly raise eyebrows and put you under scrutiny at the dealer because of the definitely not stock "hey this is a BOV" noise coming from under the hood.

Here's a link for the Forge units with descriptions and videos:http://www.sonicownersforum.com/for...74-possible-1-4t-bpv-upgrade-coming-soon.html. and another one:http://www.sonicownersforum.com/forum/bad-news-racing/5106-bnr-forge-bypass-valve-installed.html.

Then the other loudest and most expensive option is the Charge tube with a BOV. It's the traditional method of installing a BOV and can be equipped with many different makes of BOV upon request. It's in your face as soon as you pop the hood and also loud so good bye powertrain warranty...

That's all the intake side of things. On the exhaust side you need a Catless downpipe, preferably 2nd cat delete, and a cat back loud enough to hear the exhaust and you'll get sweet sweet turbo spool noises.

Just in case.

Wow man thanks a lot! I honesty didn't think I'd get such a good one!! I think I'll go with the hole in the box for now. We will see. Thank you very much again!!

You should copy/paste/sticky this in its own thread. That's some excellent comprehensive info there.

Do we have a FAQ thread that has links to the answers for these? I work this weekend, maybe I'll have time to put one together.

I KNOW there's a search function, but we know how often it's used (and probably so will the FAQ thread) and it can get frustrating at times even when you know the exact title of the thread you're searching for.

good idea. I may get around to making one some time in the interim future. If you'd like to do it sooner be my guest. It would be really nice to get a comprehensive thread with this stuff and other warranty concern things sticky-ied.

And sadly even using the "quick search" doesn't show very good results. Today I searched Dyno Thread to find a topic that I started, using those words and it was the 4th or 5th hit :blankface:.

The "advanced search" on the otherhand works very well.

It's what we're here for

I would think the way to do this without violating the warranty would be to install a mike, amp, and speaker system. Since it's just the noise, not actual performance boost you are looking for, this would allow you to get the sound without touching a single engine part. Even better, you could put a volume control in your dash, so you could go from the subtle, barely audible sound of a stock Sonic, to a full, deep throated Ethel Merman PSSST.

The funny thing is that the Focus ST, GTI, M5, and a bunch of other cars essentially do this. The GTI and ST pipe in the noise, and the M5 has artificial engine noise played through the speaker.

What a coddled ridiculous world we live in :laugh:

If you want to be even cheaper and more warranty friendly, you could remove this little intake resonator thingy.

It's not going to make as much noise as an actual Cold Air/Short Ram Intake, but it definitely amplifies the wastegate and bpv sound (compared to stock).

It's located right under the airbox (it's between the airbox and the fender opening) and it takes like 5 minutes to remove.
