keithk831 Posted March 21, 2011 Share Posted March 21, 2011 In a different thread I posted about my new SPT catback. I like how it looks as well as the extra midrange torque, but it drones a little with my Stage 2 setup. Someone locally is looking to trade his Borla for an SPT. Would that be a good move? Less drone on a Stage 2 setup? I wouldn't mind it being a tad louder, I just want no drone on the inside. Link to comment Share on other sites More sharing options...
planelazy Posted March 21, 2011 Share Posted March 21, 2011 you could always take it to an exhaust shop, chop up the mid pipe and install a 3rd muffler or a resonator Link to comment Share on other sites More sharing options...

Blk2.5GT Posted March 25, 2011 Share Posted March 25, 2011 Get the Magnaflow...I love it I think you can get it for $550 from Subimods. I bought mine used for about a year and cleaned it up and it looks brand new. They have a decent warranty too. Link to comment Share on other sites More sharing options...

aaronlee0821 Posted March 25, 2011 Share Posted March 25, 2011 with any stage 2 setup, (catless up and catted/catless dp) im pretty sure any aftermarket exhaust will drone.. some will drone more than others, but unless you get a resonator added on, the catbacks will have drone. or you could just add dynamat under the already insulated carpets to keep some droning noises out of the car.. never tried but heard it helps. i got used to the droning. I had catless dp and straight pipe single exhaust.. Link to comment Share on other sites More sharing options...

I had catless dp and straight pipe single exhaust.. Yeah...my Perrin cans with stock midpipe doesn't drone at all...so i'm wondering if having a resonator in an aftermarket exhaust makes all the difference. I also noticed with my last car that chambered mufflers drone WAY more than straight-thru designs (SLP vs Magnaflow). So muffler design has a lot to do with it also.

Blk2.5GT Posted March 26, 2011 Share Posted March 26, 2011 With the Magnaflow you can't really notice any "drone" when the radio is on, or when you take your foot off the pedal...nice exhaust, really. I have had mine on for two weeks and I love the damn thing, I sometimes cetch myself driving with the radio off and the windows cracked just to hear the damn thing.

TRSCobra Posted March 26, 2011 Share Posted March 26, 2011 Keith, is your aftermarket DP catted or catless? Link to comment Share on other sites More sharing options...
AdAstra Posted March 26, 2011 Share Posted March 26, 2011 I have a Borla CBE with a CNT catted DP. I haven't noticed drone under any condition. In fact, I had installed the CBE before the DP, and at cruising speed the addition of the DP added very little volume. In town, with the windows down, the increased sound of the DP is definitely noticeable-in a very good way. Link to comment Share on other sites More sharing options...

Drogos Posted September 8, 2013 Share Posted September 8, 2013 any more opinion on SPT vs. Borla on catted COBB DP? utube seems to suggest that Borla is little louder? Friend stopped by in his 11 STI yesterday. Turbo X catless and SPT. It sounded pretty much perfect. Link to comment Share on other sites More sharing options...

Burke25thID Posted September 9, 2013 Share Posted September 9, 2013 Stage 3 with a borla cbe and megan downpipe. Car is very quiet on the inside almost stock "big sleeper" The downpipe barely made a difference in noise. I have a 46mm ewg so i have the best of both worlds .

CapnJack Posted September 11, 2013 Share Posted September 11, 2013 any more opinion on SPT vs. Borla on catted COBB DP? utube seems to suggest that Borla is little louder? Friend stopped by in his 11 STI yesterday. Turbo X catless and SPT. It sounded pretty much perfect. I've got the SPT V2 with a Cobb catted DP. It does drone a little at about 68-72MPH, but nothing significant. Anything below or above that, it is quiet. Since you have a Spec B, it may put you in a different RPM range at those speeds.
