Received some JCR silenced titanium tips today. Arrived well packed. Construction appears to be solid. Cast titanium backing plate; two mini mufflers with internal perforated pipe/steel wool packing; turn down tips.







The JCR tips are pretty light - lighter than the steel 991.1 RS tips, but heavier than the titanium 991.2 RS tips.

JCR - 1400 grams
991.1 - 1550 grams
991.2 - 900 grams









Test fit went fine. They look good - I could definitely drive to the track with them mounted and leave them on for an extended period of time. Typical turn away pipes I would always install and remove at the track.







Laguna track test with dB readings soon...

Are you running stock muffler/side muffler or JCR?

Stock exhaust. Plan is to test back to back dB readings of:

1. Stock w/ and w/o JCR tips
2. Stock + gps activated valve control w/ and w/o JCR tips

Will be looking to see if the dB delta is the same in both scenarios.

After one session, tips turned a nice blue. I guess they are made of titanium, after all! No issues passing 90db on a very foggy morning at Laguna Seca in conjunction with exhaust valve GPS controller. It was also rather peaceful having a quieter exhaust on the drive back home.

Excellent, great to see another customer happy and running on track without issues!

Do you have decibel readings without the Track Nanny? Just curious how much they reduce the loudness with stock exhaust.

A further review here should help
