steve'66 Gearhead Posts: 5659 From: Sonoma,CA,USA Registered: Mar 2000	posted 11-22-2002 09:09 PM Compared to single chambered Folwmaster race mufflers? Rob, you run Borlas right? I got a line on a pair of the 3" X 15" long ones for the other project. Will it be quiet enough to drive to the track w/o tickets? SteveW IP: Logged

kid vishus Gearhead Posts: 3894 From: middle of NC Registered: Oct 2000	posted 11-22-2002 09:20 PM I dont know about the ticket Steve. I have 3.5" in/out 16" long Borlas on my car, and although they are fairly quiet for a racecar, they would probably be considered loud for a street car. They do have a really deep sound to them, unlike the flowmaster race muff's. I'm sure the slightly smaller diameter would help quiet them some, but I'm not sure if it would be enough. Another thing to remember is, I dont have any pipe on mine. They have been welded to flanges and are bolted directly to the hedder collector. Some actual exhuast pipe might quiet them down a little to. I have to unload it tomorrow to do a little wiring on the 'brake, and also to change the oil. If you want, email me your home phone # and I will call ya and you can hear for yourself. IP: Logged
steve'66 Gearhead Posts: 5659 From: Sonoma,CA,USA Registered: Mar 2000	posted 11-22-2002 09:37 PM Rob, That's cool but I'll own them tonight. We run the 1 chamber 3" flows on the 'stang and it's trailered to the track. I think I could get away with driving that if I stayed out'a the go peddle. I'm gonna run the Borlas with no tailpipes too, so It'll be good. I'll e-mail my number, and feel free to call anytime. SteveW IP: Logged

They have a very mellow tone without tail pipes slipped on right over the collector. I have them on the convert so we can move the car around without annoying the neighbors. Borla gave some to us for R&D work and we tried them on all three cars. They slowed MM down .15 and Tony's car and the convert both a full .2. If you intend on doing any serious racing with mufflers succesfully, you need to have a custom cam ground. ------------------ Alex Denysenko Co-Administrator and Moderator NHRA/IHRA/SRA member and licensed Superstock driver MCA member# 53321 NHRA and IHRA SS/LA National Record Holder '00, '01, & '02 Fleet of FoMoCo products including 88 ASC McLaren Mustang #28 Professional Manwhore The Barry of BarrysGrrl Quote #1: "I never met a magazine mechanic I liked."

I got the pair for $102 so I can't bytch. We'll give them a try next season. Most of our racing is all corked up Alex, I know, but the future of our sport will have to make h.p. thru the mufflers.

WOW. I must be lucky. Mine didnt slow the car down even .05. Maybe it's because mine are 3.5" diameter? IP: Logged

Moneymaker Administrator Posts: 18704 From: Lyons, IL, USA Registered: May 99	posted 11-23-2002 11:26 AM Clarification. KV runs a 950 CFM carb on his car vs the 400 CFM carb that I use on MM. Although he is correct, there will be much less loss in performance with a 3.5 muffler, the greatest variance is in the size of our carbs. There will be much less loss with a large carbed engine as it does not have to fool itself. There is far less reversion with a large carb. ------------------ Alex Denysenko Co-Administrator and Moderator NHRA/IHRA/SRA member and licensed Superstock driver MCA member# 53321 NHRA and IHRA SS/LA National Record Holder '00, '01, & '02 Fleet of FoMoCo products including 88 ASC McLaren Mustang #28 Professional Manwhore The Barry of BarrysGrrl Quote #1: "I never met a magazine mechanic I liked."

Oh, I never took the carb into consideration as to having an affect with mufflers. But it makes sense. I learn something new everyday if I pay enough attention. IP: Logged
