Strawman Posted June 17, 2013 Report Share Posted June 17, 2013 Since the installation of the Kenne Bell, the exhaust note on my GT/SC has been muted significantly. Why does this happen, and what can I do to get the rumble back? Link to comment Share on other sites More sharing options...
AstroDan Posted June 17, 2013 Report Share Posted June 17, 2013 Hmmm. Really? That's semms strange to me. Maybe lean on the throttle! Link to comment Share on other sites More sharing options...
Elgin Black Posted June 17, 2013 Report Share Posted June 17, 2013 I can't figure out why the exhaust note would change.I would try AstroDan's solution and try some more throttle. Link to comment Share on other sites More sharing options...
ITHERTZ66 Posted June 17, 2013 Report Share Posted June 17, 2013 I never had a chance to hear my Hertz prior to the S/C installation, but I don't think my car sounds at all like the ones in all the videos. Mine seems very quiet in the exhaust department as well. All I can hear is the S/C when I put my foot in it. Perhaps that is the problem also with the OP?

Jer Posted June 18, 2013 Report Share Posted June 18, 2013 The original exhaust was only mildly more aggressive than stock, but very cool. The blower should not change a thing. Just "more of the same". Jer Link to comment Share on other sites More sharing options...
Blown Away Posted June 18, 2013 Report Share Posted June 18, 2013 I immediately noticed that the car wasn't as loud at WOT when I drove it for the first time after having the whipple installed. Before, when revving it, or driving WOT it was more aggressive sounding. That being said, I'll take the extra power over the sound any day of the week.

Mine seems very quiet in the exhaust department as well. All I can hear is the S/C when I put my foot in it. Perhaps that is the problem also with the OP? I rented and drove GT-H's several times before purchasing my SGT. One of the most enjoyable aspects, to me, was the throaty exhaust note. When the SGT was returned to me by SAI during the CARB fiasco (pre S/C) I felt the same about the sound. Post S/C, I believe the exhaust is much quieter, others agree. Maybe I'm going so much faster the sound can't keep up? Link to comment Share on other sites More sharing options...
ITHERTZ66 Posted June 18, 2013 Report Share Posted June 18, 2013 Perhaps something in the tune or change in the CAI is the key to all of this? If I could find another SGT or GTH in town we could do some comparison vids... Link to comment Share on other sites More sharing options...
bnoslo Posted June 19, 2013 Report Share Posted June 19, 2013 Do you have any power/boost problems? If it feels down on power maybe check the bypass valve and see if it is in the valet mode. If power is good, i don't have any other ideas. Link to comment Share on other sites More sharing options...
Strawman Posted June 19, 2013 Author Report Share Posted June 19, 2013 Regardless, I'd like to "toughen" my SGT's exhaust tone, how can this be accomplished? Can I get away with a new set of catbacks, like Borla stingers, or would an O/R midpipe be essential? HAs anyone changed their GT/SC exhaust?

Strawman Posted June 24, 2013 Author Report Share Posted June 24, 2013 Upon further review, I've decided to keep the GTA exhaust/muffler setup, and try to achieve more volume through a mid pipe change. I'm considering changing the SGT's x for a MAC Prochamber, has anyone tried this or any other midpipe change? Thoughts, ideas? Link to comment Share on other sites More sharing options...
