ZAP No boost, no bottle, just my foot on the throttle!

This will free up the motor and make it breath better.There are many choices, but a single 2 1/2 is not suitable if standard it comes with 2 x 2 1/4. Get the same or slightly bigger like dual x 2 1/2. Link to comment https://www.fordxr6turbo.com/forum/topic/34943-advice-needed/#findComment-532066 Share on other sites More sharing options...

There's all sorts of au xr8s with different exhausts over there and they're all happy with what they've got.http://www.fordforums.com.au/showthread.php?t=92277There's even a thread with sound files if you do a search.There's guys with 220rwkw+ with single 2 1/2 inch systems (which cost as little as $400 and by all accounts, will improve power over stock)) and lots of supporters of twin 2 1/2 inch systems for under $1000. It seems anything you do will add power over standard Ford stuff, due mainly to using straight through mufflers. Not sure where you are, but Mettam's Mufflers in Perth quoted me $400 for a single 2 1/2 system with straight through muffler.I'm just going to remove a centre or rear muffler for better sound - Its not worth trying to chase power in an XR8 for me after owning an XR6T!Mark Link to comment https://www.fordxr6turbo.com/forum/topic/34943-advice-needed/#findComment-532081 Share on other sites More sharing options...
