jeisen Posted October 6, 2013 Share Posted October 6, 2013 I have an 08 LGT with an SPT catback and intake. I'm think about going stage 2 but the one thing that is holding me back is the added noise level of a catted downpipe vs. the stock downpipe. I was looking at a Cobb or Invidia catted downpipe. How much noise increase are we talking here? I leave early in the morning and I don't want to piss off my neighbors. Thanks guys. Link to comment Share on other sites More sharing options...
510Finn Posted October 6, 2013 Share Posted October 6, 2013 Not much louder than the stock DP. I have Borla header, Invidia up, and CNT catted DP, SPT v2 CB and it is almost too quiet.

BoozeRS05 Posted October 6, 2013 Share Posted October 6, 2013 ^ Agreed. I have a GS UP, Cobb DP and SPT CBE, and I'd say its quiet. Marginally louder as with the stock DP. The stock DP and Magnaflow CBE on my sedan was twice as loud as my current TBE setup.

iNVAR Posted October 8, 2013 Share Posted October 8, 2013 Interesting. I found my SPT CBE to be too loud, and droned on the highway. Really needed a 3rd muffler put in. Different strokes for different folks. Link to comment Share on other sites More sharing options...
PtPixel Posted October 8, 2013 Share Posted October 8, 2013 I'm catless stage 2, didn't notice any noise increase with the change. NZDM have equal length headers though if that makes a difference, not as much of a rumble. Link to comment Share on other sites More sharing options...
shutterbc Posted October 8, 2013 Share Posted October 8, 2013 No significant noise difference for me either with the CNT catted dp. However I'm hearing more rattling than I did a year ago and can't help but wonder if the cat is failing.

Moddiction Posted October 14, 2013 Share Posted October 14, 2013 Not really louder but there is a very very slight drone with windows opened when stopped in my 08 LGT with the CNT catted downpipe. All other exhaust is stock. WWW.MODDICTION.COM Moddiction Stainless steel and Titanium shift knobs. Drivetrain, suspension, brakes, exhaust, cooling, fuel, gauges+MUCH more!
