Gas has cooled a bit as it get down there though. Wouldnt want that over 300rwkw Link to comment https://www.fordxr6turbo.com/forum/topic/79156-twin-25-into-3-single-over-diff/#findComment-1204403 Share on other sites More sharing options...

Looks like I should have done my research first.

Kristovic Member 8 Member For: 13y 7m 11d Posted 02/03/12 02:18 AM Author Share Posted 02/03/12 02:18 AM Sounds like a plan! Next question 3.5" or 4" over the diff? Planning on making around 350rwkw for now Link to comment https://www.fordxr6turbo.com/forum/topic/79156-twin-25-into-3-single-over-diff/#findComment-1204539 Share on other sites More sharing options...

BRK Member 361 Member For: 13y 6m 25d Gender: Male Location: Perth Posted 02/03/12 05:39 AM Share Posted 02/03/12 05:39 AM You have a problem there. If I remember rightly, the insides of that muffler will have a single 76mm pipe somewhere in it as well so changing the outside bit - the "over the diff" section will not help. Cutting mufflers and fiddling with the inside is a tough job without the right sort of gear - and may not do much at all other than add noise.For 350 RWKW the general consensus is a single 90 MM or twin 63.IMO - and sorry to say - classifieds might be where it will need to go.
