Roger Maestas: allows to to open a valve in the muffler to gain sound, or close it to
silence the sound
TonyTube407: That whistling sound is almost as bad as fingernails on a chalkboard.
Sounds good with the valves open though.
Cristian Moncayo: Where can I buy it ?
Lancr04: Why is it whistling like that??
Tony Filicetti: when can we hear this on a 2.0T...
Paul Walton: @laverkfc4stitching well obviously this is for a optima, not a camaro, no
one cares about your old POS. Take your condescending remarks to another
video, maybe something involving a camero? Jackass...
Steve Song: damn internet trolls...i have 69 camaro so i am gonna come here and bash
decent daily driver sedan...yeah...nothing to say just ignore these ppl...
Paul Walton: @laverkfc4stitching you mad? lol
Enis McPenis: Bit of an annoying whistle there...
Shon Conner: I'm liking that alot, just bought an Optima. Maybe an up coming upgrade for
TheTexasHitmen: I'll stick with my '07 Sonata. Don't get me wrong. I love the styling and
the performance of the new Sonata and it's sister car from Kia but I can't
get used to the sound it makes through a performance exhaust. Maybe I'm
used to the extra two pistons or maybe it's the exhaust. The whistle it
makes when it's closed drives me nuts. Sound good when it's open though.
Because it's a great car and it sounds good with the valve open I'll give
it a "like".
Gaz Murphin: oh lool gay sound compared to my camaro 69 ss
The4x4life: @laverkfc4stitching old school for life !
IronSoul: Wtf is that whistling sound ?

away of my sight otherwise my camaro will take it for a snack DOUCH
Cert: Building stuff is always in my family gene. My dad is a new york auto technician and taught me everything I need to know about cars. Now I sell car parts online to suppliment my income. So it does help when there's good guidance.
