Longer stacks as in longer runners means more torque while shorter ones mean more power. Not lots, but it all contributes to a freer flowing intake which helps your freer flowing exhaust to make a bit more power/torque and slightly better fuel economy. You note vintage racers usually have anywhere from2.5 to 6 inch stacks. Some with a stocking for a coarse filter, most just hoping nothing of consequence enters the throat… I have a set of 2.25 inch stacks in my 3.25 inch K&N’s on my MGB and they seem to help. Just the ho hum stock setup on my Magnette.<o:p></o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'><o:p> </o:p></span></p><div><div style='border:none;border-top:solid #E1E1E1 1.0pt;padding:3.0pt 0in 0in 0in'><p class=MsoNormal><b><span style='font-size:11.0pt;font-family:"Calibri","sans-serif"'>From:</span></b><span style='font-size:11.0pt;font-family:"Calibri","sans-serif"'> zmagnette-bounces@autox.team.net [mailto:zmagnette-bounces@autox.team.net] <b>On Behalf Of </b>Richard Greenberg<br><b>Sent:</b> Wednesday, November 13, 2013 12:34 PM<br><b>To:</b> List for the Z Magnette Group - North America<br><b>Subject:</b> Re: [Zmagnette] Stub stacks<o:p></o:p></span></p></div></div><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>What is a stub stack?
