Glass Packed Baffle Insert for TWIN TIP versions of SuperStreet and SuperQ.

After installing my SQTT in my RF I decided that while I really loved the look of the twin tips and the throatier volume in general, there was a bit of unpleasantly loud drone-volume that was above my personal threshold for enjoying the car's acoustics. I ordered two packed baffles for my SQTT to suppress the undesirable noise. The packed baffles arrived in a timely manner. The installation was simple but I did use a bit of PB Blaster and an impact wrench to easily and quickly loosen the bolts of the original non-packed baffles that came installed on the SQTT.

Using the penetrating oil alters the bolt's thread resistance within the captured nut of the baffle so I found the fitting too "slippery" to get to Brian's recommendation of 15 lb-ft of torque. I watched the bolt rise in the captured nut until it was just slightly above the top of the nut's surface. I felt that that amount of threading was sufficient without risking pulling the fitting through the baffle and I did not want the bolt uncosmetically protruding up into the exhaust pathway. I used a manual socket wrench to set the bolt and I felt the progressively increasing force involved to set the bolt in place to be sufficiently tight and secure.

The reduction in undesirable noise was good but not perfect across the full RPM range. Most all of the unpleasant drone-volume was diminished with one exception. With the RF top up (enclosed car) in the 2.5K RPM range, the drone-volume tips into the uncomfortable. With the top down (open car) the sound is perfect in all RPM ranges. I think the hardtop captures the noise in some way that magnifies the intensity. Also I think that with the car open, wind noise is a form of "white noise" that negates some of the unpleasant frequencies of the SQTT.

The packed baffles work well enough to be satisfied with the product. I'm hoping that as the new SQTT ages with miles, the tone will also mellow and further improve the acoustic experience.

I'm running the Goodwin Racing long tube header V1 and midpipe with the magnaflow muffler that hangs low paired with the non header version of the superQ twin tip. I purchased two of these tip baffles (60-1324T Glass Packed Baffle Insert for TWIN TIP versions of SuperStreet and SuperQ). They help to reduce noise without a doubt. I would like to try the header version of the superq (has an additional resonator) and remove the magnaflow resonator in the midpipe, but this solution has an acceptable noise level while minimizing the performance loss.

I bought two of these because they dampened the sound level to a very acceptable level. Especially I had to go to work either super early or late night, and I do not want to piss off all my neighbors. They work great, and I am now able to enjoy my music while cruising highway and still get the accoustic of my Superstreet Twin Tip exhaust.

I loved the tone of the SuperStreet Twin Tip with the mixing baffle all the way in, which if I read the descriptions correctly effectively makes it a RoadsterSport Race. I was pretty self-conscious driving around with it in that configuration, and quickly picked up this glass packed baffle. Best of all worlds now, at least in my opinion. I do not feel overly obnoxious but love the tone this system puts out. Thanks for all the configuration options, GWR!

I wanted this in case I wanted to take a long highway trip. It's a lot quieter and more even in tone, keeps the wife happy. LOL

As Brian has stated in ever video or wrintten commentary, exhaust sound preference is very personal. For me my stock system with twin tip super-Q was fine with or without baffles. When I added the stainless midpipe I got a little too loud on acceleration. The packed baffles lowered the exhaust volume and add lower growl. Hopfull not much HP is lost with them inplace.
