super7guy Posted January 2, 2015 Posted January 2, 2015 Just finished the modifications to a C5 titanium muffler. This muffler weighs 7 lbs without the heavy (2 lb) SS strap. Required welding the titanium flange to the end of the muffler, so that the remaining tubing can be SS. This is a 2 pass muffler with dual outlets (inlet and outlet on same end). Can supply pics on request. Wayne super7guy7@yahoo.com
super7guy Posted January 3, 2015 Author Posted January 3, 2015 Have yet to hear the sound and sure hope that it meets our "Q" requirements of 93db@50'. Guessing that it will have a unique sound. Have more fabrication to get it installed on the side of my Cat Will have 3 bolt flange off header, 180 bend and 2 bolt flange to match up. Everything is 2.5 dia.
coffee break Posted January 3, 2015 Posted January 3, 2015 I'm guessing it's going to be hanging under the rear of the car. Right?
super7guy Posted January 24, 2015 Author Posted January 24, 2015 Completed the fab and installation of the muffler today. So far sounds throatier. Now have less weight hanging off the side the car. Lost at least 10 lbs. Find out on Sunday, if sound is under 93db @ 50 ft. Our requirement at the stadium. Wayne
xcarguy Posted January 24, 2015 Posted January 24, 2015 That's a first, super......love it. Here's to successfully passing inspection. :cheers:
randychase Posted January 24, 2015 Posted January 24, 2015 It is going to have a lot to do with which side of the car the meter is on I would think. Any provision for making a "mechanical change" if you are over 93?
super7guy Posted January 24, 2015 Author Posted January 24, 2015 Randy, If you remember, the old setup consisting of a bullet and Ultraflow combination did not need a direction deflector. so hoping that it is the same for this one. One main difference is that this one blows straight down whereas the older was straight back. Time will time. So far, the titanium and twin pipes seems to reduce the 4 cylinder raspiness (if that is a word) Wayne
super7guy Posted January 26, 2015 Author Posted January 26, 2015 Sundays results were under the sound meter, but the meter was opposite the exhaust side. All modified cars have to work hard to meet the sound requirements at the "Q". I seemed to hear the intake noise more clearly (its intake is from the cockpit through the heater opening), so maybe the exhaust noise is reduced. Engine seemed to rev quicker, so maybe I have a winner here. Wayne
randychase Posted January 28, 2015 Posted January 28, 2015 I noticed you only took two runs Wayne. Was that due to sound?
