Bill_Cosbys_Nightmare Posted June 28, 2007 Share Posted June 28, 2007 I just installed the K&N typhoon, and I'm totally NOT digging the BOV sound it makes when shifting. Does anyone out there share the dislike for the BOV sound? Is this the BOV I'm hearing now or is it something else? Has anyone done anything resonance-wise or something else to reduce or eliminate this sound? I'm not knocking those who like the BOV sound, but i'm just saying it's not the sound i was looking for. I would like to find a way to keep the less restrictive air intake though as i'm planning to install a cat-back or turbo-back at some point. Would a tune help at all? Would adding a less restrictive turbo back exhaust help reduce the sound? I'm guessing not with my somewhat limited understanding of the GT engine...

itsme Posted June 28, 2007 Share Posted June 28, 2007 As far as I know all of the aftermarket intakes make that noise. I would say go back to stock. When I got my TBE(turbo back exhaust) it seemed to get alittle louder. I'm at stage 2 now. The tune made the intake sound alittle deeper.

Max Capacity Posted June 28, 2007 Share Posted June 28, 2007 Some of us like the sound. Remember you just installed a performance part.

mikefoy6 Posted June 28, 2007 Share Posted June 28, 2007 FWIW what you are hearing is the BPV (by-pass-valve) not a BOV. If you dont like it, just turn up the radio lol! Its actually not as loud on the outside of the car as you think. A tune will not help, i would think it would make your suck more air in and increase your boost levels making the BPV sound even louder. Link to comment Share on other sites More sharing options...
zmarko Posted June 28, 2007 Share Posted June 28, 2007 Its actually not as loud on the outside of the car as you think. Yes it is. lol. Installed my Typhoon over the weekend, and it's coming off today. Link to comment Share on other sites More sharing options...
bdisco Posted June 28, 2007 Share Posted June 28, 2007 If you dont like it, just turn up the radio lol! Did you get that advise from my wife? My Blitz panel filter makes more "whoshing sounds' then the stock one does. Link to comment Share on other sites More sharing options...
psucaptainkickass Posted June 28, 2007 Share Posted June 28, 2007 The sound actually gets quieter with time. That, or I am just getting used to it. Link to comment Share on other sites More sharing options...
TDC Joe Posted June 28, 2007 Share Posted June 28, 2007 I would suggest you go with the AEM intake then. Sell the KN you will get better performance (colder air) and you can barely hear it. It is the best "stealth" intake out for this car! Joe PM Me for all your Modification Needs! Link to comment Share on other sites More sharing options...

psucaptainkickass Posted June 28, 2007 Share Posted June 28, 2007 ^ No, because it doesn't sound like crap 10k miles later. (Damn did I really have it on for that long...<moment of realization>) Link to comment Share on other sites More sharing options...

It is the best "stealth" intake out for this car! Joe This is what I did. The AEM CAI actually filters the sound through the tire well so it's not quite as bad as the short rams. I only hear a little hiss when barely giving it gas. With the UP/TBE; the exhaust rumble will drowned out the intake. I don't even hear the woosh when shifting anymore. Let's kick this pig!

LegacyGT 05 Posted June 28, 2007 Share Posted June 28, 2007 The sound actually gets quieter with time. That, or I am just getting used to it. More air flow=more noise as the turbo will suck down a heck of a lot of air. It gets quieter because your filter is filling with crap That's the point of filters. Clean and/or replace it and the noise will come right back Link to comment Share on other sites More sharing options...

turbobum Posted June 30, 2007 Share Posted June 30, 2007 How much louder is the AEM intake than stock? I had the k&n typhoon system on my car and took it off a month later. I couldn't take the noise anymore. It's a great performance part, just not for me. So, I was hoping the AEM system was quiet(er). Link to comment Share on other sites More sharing options...
