exhaust???

[pro4dude14]

im running a through the firewall header and ran a pretty short exhaust last year about 3 feet actually had a few people tell me it needed to be longer and i was losing a decent amount of power because of it what is yalls take on this and how long should it be

if you search 84Dave he wrote a rather long,yet very interesting article on this exact topic.

basically you tune the exhaust to your engine combination...if you have unlimited access to a dyno that would be the best way...another trick is to paint the exhaust and see at what point the paint is no longer burning off after a run...or so ive been told.

i took daves advise and got pipemax well worth the 45 bucks

[84Dave]

Please let us know your operating rpm band & what PipeMax says for the length(s) of your exhaust/tailpipe. What are the ~lengths of your header primary tubes from the flange out to where the primaries terminate inside the collector? I'm currently working with a team that road races, and the difference between the longest & shortest primaries on the Schoenfeld header they're using is 11"-12"! Might be good for limited installation room, but totally lousy for proper exhaust tuning. It all has to work together! -Dave-
