Cary Brooks Verified Owner Friday, Oct 2 2020 (about 4 years ago) O.S. PowerBoost 105HZ Helicopter Pipe Great pipe for pairing with the 105 HZ DRS. I have 5 gallons through my current engine and pipe and still no leak at the engine to pipe joint. Finish is very nice on the pipe and it is lightweight. It does a very good job of silencing the big powerhouse of a motor. 1 customer found this review helpful. Juan C Melendez Verified Owner Friday, Jun 12 2020 (about 5 years ago) O.S.
