Haribo1187 Posted February 17, 2007 Share Posted February 17, 2007 Hey guys... I curently own a MY99 Uk PPP - Ive got Blitz Nur Spec R cat back and was wondering if anyone could recomend a good downpipe that would give best performance ?? Also lookin at headers but there so many different ones out there and struggling to decide.. Anyone any ideas what to go for ??? GT Spec II ???... I noticed flat4 do a cheaper alternative that claim to be the exact same as the GT Spec without the name - Kakumei make them im sure.. Are there any other good makers - I noticed DC Sports make them aswell.. Greddy Etc.. Just another quick question, sometimes my car seems to back off underpower in higher gears, like 4th and 5th - sorta gets acelaration then kinda nothing for few seconds then acelarates again... Its a weird feeling.. Possible coil packs ?? MAF ??? How much these cost to replace ??? Cheers For All Your Help... Andy Link to comment
colin_ross Posted February 17, 2007 Share Posted February 17, 2007 GT spec II seem to be very highly rated. I've got a set ready to go my car so while I can't comment on performance or sound I can say that they seem to be well made and I haven't heard any horror stories like you get witl megans's etc. Link to comment
diffbuster Posted February 17, 2007 Share Posted February 17, 2007 Dont with a capital D buy cheap ones you will regret it, if possible avoid flexi joints i searched for equal length without a flexi and got them from america and still regreted it.Next remap its back to ported and polished standard manifold with a return to the burble gt or gruppe s seem to be highly recomended though.

oz *sti* Posted February 17, 2007 Share Posted February 17, 2007 I did have a cheap headers with the flexi joint and the joint let go after a few thousand miles!!!! I now have RCM headers great quality [] Link to comment
Haribo1187 Posted February 18, 2007 Author Share Posted February 18, 2007 Cool.. Well the Kukamei ones on flatfour claim to be the dogs, say they just same as the GT Spec II.. Its abit of a hard decition with so many choices.. What is the difference in power gains between equal and unequel ?? I no there is a substantial change in noise etc.. I would prefer to keep the burble.. Anyone have an idea for a good downpipe ?? Hayward and Scott downpipes and headers ?? Cheers.. Andy Link to comment
frank c Posted February 18, 2007 Share Posted February 18, 2007 I opted for the H&S open neck downpipe, cracking piece of kit as for the headers i've no experience here, i was thnking of getting Harvey to port my OE ones. Link to comment
fai17 Posted February 18, 2007 Share Posted February 18, 2007 Gruppe S,real GT spec2 and Greddy headers. Meercat snakehead downpipe all the way m8. Link to comment
WUZ Posted February 18, 2007 Share Posted February 18, 2007 Any of the above headers WILL REQUIRE A REMAP! H&S D/P are the dogs! - but I am biased as I suipply a lot of them to people! Same with "real" GT Spec II headers...........Good Prices too! Russell Link to comment
