: Sound and Performance of Spin Tech Chas67 Jan 8th, 05, 11:32 AM Has anyone used the Spin Tech mufflers and oval tubes for clearance with a BBC? I am looking at a custom exhaust and was wondering about sound quality and flow. I will want to use 3.5" pipes after the headers. I am looking for clearance but also performance. Thanks Adman Jan 8th, 05, 3:02 PM they are LOUD Ron454 Jan 8th, 05, 3:39 PM I used the 3" Spin Techs and they were loud. performance was excellent though. 0 mph loss in the 1/4 with them on or off. Ron TD509EFI Jan 8th, 05, 7:43 PM What model were you guys running? Looks like SpinTech has quite a few. Their Sportsman Street or Sportsman Street XL are supposed to be very quiet at idle. John JWA Jan 8th, 05, 8:10 PM Jeff Kinzli has spin techs on his blown 67. There is a sound file on his page: http://www.kjsl.com/~jk/chevelle/indexa.html BowtieAaron Jan 8th, 05, 10:48 PM LXS388 ( i think his name is) runs spintechs. he said they sound awesome, on a worked engine. compaired to flows... flows were just noise, with techs, u could hear the cam perfect. ive heard a few of their soundclips, and am sold on them, but money is really tight. aaron notstock71 Jan 8th, 05, 11:45 PM The Spin Techs seem real popular over at the www.dodgemagnum.net (http://www.dodgemagnum.net) site. Sorry for crossing brands here but I have a Magnum R/T also. Seems they are preferred over the Flowmasters by many. I personally am a faithful Flowmaster guy. blaauboer Jan 9th, 05, 9:26 AM Are they as loud as the Bullets ???? When letting off do they cackle,pop,like a cherry bomb ?? I am looking to dump the flow masters for a better flowing muffler but I'm one that still likes loud..... :eek: :eek: just not bullet loud.I was thinking maybe a one chamber race Flowmasters but I'm afraid that to will be to loud also. BigRed-L72 Jan 9th, 05, 10:37 AM I`ve only heard them when coupled with an X-pipe. They have a sound all their own; a 2 stroke big block comes to mind, or maybe a huge chain saw like 500 cu.in. on nitro with an expansion chamber. They have a high pitched, buzzy, resonating rasp that at WOT sounds like 10,000 rpm instead of 6500. One thing`s for sure, you`ll have people coming up to you in the staging lanes looking to see what`s making that "sound" motown/malibu Jan 9th, 05, 2:30 PM try flow tech 3 inch peurple horny,s same rthing same flow less cost | ||
