*Toymota* Posted January 29, 2006 Share Posted January 29, 2006 My Glanz has got a powerflow exhaust system will I still get a power increase or would an aftermarket jap system like HKS etc be better??Ta Quote Link to post Share on other sites
starletboy Posted January 29, 2006 Share Posted January 29, 2006 prob wont have a power increase depends on size of bore and routing etc generally powerflow are not performance inhancinh exhausts would be better with a jap specific system such as hks,blitz or kakimoto which are very very good!!!!!!!!!!

gaz Posted January 30, 2006 Share Posted January 30, 2006 on gtt.com WEPR and AUTOFIXED do kind of custom systems with no restrictions. im buying one in the next few days, if you want power id reccomend those. Quote Link to post Share on other sites
DAN_GTT Posted January 30, 2006 Share Posted January 30, 2006 Yeah i have a Autofixed turbo back system and noticed a HUUUUUGE difference from stock Quote Link to post Share on other sites
scutch0 Posted January 30, 2006 Share Posted January 30, 2006 dont the mandrel bent powerflow systems restrict anyway beacause of the bends being narrower?Rich. Quote Link to post Share on other sites
BlackTarw Posted January 30, 2006 Share Posted January 30, 2006 Mandrel bends are what you want as it maintains the diameter throughout. Quote Link to post Share on other sites
lobotomy Posted January 31, 2006 Share Posted January 31, 2006 Yep this is true. The larger the diameter of your pipework the larger the radius of turn you will need to keep Ã? constant though. Won't really matter for 2-3" exhaust pipework though. Quote Link to post Share on other sites
BlackTarw Posted January 31, 2006 Share Posted January 31, 2006 indeed, but I'm fussy with bit's like that! Nothing goes on my cars without it being flow-benched, reviewed and road tested to prove it's worth Quote Link to post Share on other sites
gaz Posted January 31, 2006 Share Posted January 31, 2006 good going. Quote Link to post Share on other sites
lobotomy Posted January 31, 2006 Share Posted January 31, 2006 Sorry. Meant to say you won't have any problems keeping the diameter uniform for an exhaust system using a mandrel... however it's a very important aspect of exhaust design in order to keep the gasses flowing smoothly that diameters are kept constant.(Just reading it back my post it never seemed right) Quote Link to post Share on other sites
