Title: Exhaust question
Post by: JayD on August 20, 2012, 10:22:43 PM
Hi guys

Where would be the best place to get a mid box for a 4" exhaust straight pipe?

I have a welder who can cut and add the mid box i just cannot source a mid box with a 4" entry

I\'m only really doing this so i dont get pulled or upset the neighbours

Grazie

:King

Could you not just get a 3" silencer and then simply cut the 3" inlet and weld on a 4"? Or perhaps you could get a 4" to 2" twin adaptor and run 2 smaller midboxes?

Umm I thought about the three inch idea but its a bit of a messy idea..

Will just create a bottle neck...

Hmmm could you perhaps look at repacking the rear muffler a bit more?

No, its an old photo from rotorstock before I bought my FC which I have just sold lol I thought....why did they need to run the exhaust to the back, just run it out the bonnet :D
