On 27/05/2010 at 1:50 AM, osonvs said: hiddeous, now your talking my language. Yes 4 speed auto. Ill only be putting exhaust on when I put the other mods on. So I only need to get one tune afterwards. What would you suggest being the best option? The SMB or the stealth? Id buy new mufflers to replace the old ones if I bought the SBD. What price would I be looking at for an auto upgrade? I think I am more worried about the diff and drive shafts buggerin out before the auto haIn all honesty i would go BF Dump, Bigger cat and leave the rest as is, Or get the stealth system, Your going to have to spend big on the 4 speed if you want it too last. Dont worry about the diff/driveshaft (unless the car is stupid low) they will outlast your auto at the power levels your talking. Why would you replace the mufflers??EDIT: Look up X-Force systems, they would be good for what you want Link to comment https://www.fordxr6turbo.com/forum/topic/68419-exhaust-buffs-wanted/page/2/#findComment-1011103 Share on other sites More sharing options...

What sort of work on the auto would I be wanting to do??? I suppose a manual would cost more to make it last?? Car is @ 100,000km nearly so I would have thought diff/drive shaft would nearly be stuffed. The mufflers on the car at the moment blast exhaust in one end, back up towards the motor in the middle, then back out the exhaust. May as well just get a straight through exhaust, more free faster flowing. Car is only about an inch lower than standard I have just heard that diffs and drive shafts break alot. I dont like exforce, anyone know of any others?4" dump, race cat and new faster flowing mufflers should do it eh? no point in replacing my exhaust with another 2 x 2.25" pipes when they are already there lol Link to comment https://www.fordxr6turbo.com/forum/topic/68419-exhaust-buffs-wanted/page/2/#findComment-1011140 Share on other sites More sharing options...

Worm A much better forum Silver Donating Members 3,808 Member For: 16y 11m 1d Gender: Male Location: Victoria Posted 27/05/10 05:40 AM Share Posted 27/05/10 05:40 AM Sorry it was 5am... I was reading rwkw. I have center muffler removed, lpg, air intake, fpv Cooler and shorter gap plugs. I am getting 280rwkw+ which is about 340 fly wheel kw. Just add injectors to yours and a cat and you will have 350kw...Just do that. Any more and you will just be asking for issues with valve springs and auto...
