Guys this is still going strong, great to see so many names

Only issues is I have the pipes for a 3.0si but am not going to fit them now due to the change in circumstances. Either can sell these on for £30.00 delivered so someone else or see if they fit the M boxes.

Sorry to all non 3.2 members :cry: , am still all over this mod but slight change in persnal direction. As a potential new owner may not appericate a more active exhaust system on my si :?

Feel bad as I started the thread... for non m's :(

I want to do this mod, but I have the Eisenmann backboxs. Can I still do this mod?

Can't see any reason why not, as long as there is enough room either side of the box to drill a 3/4in hole and weld it.

What do you think? don't forget these are almost upside down in design, so the back box is higher above the tip, rather than the hanging testicle of the standard back box..

Don't really want to mess with the Eisenmann's, but I do want that raw noise...
 
Fascinating mod.
Have those looking into it considered fitting a simple manual on/off valve (pretty much a tap) into the pipe?

That way you could in 30 seconds close the pipes for track days, MOT's, longer drives where you may not want the noise, etc.

I'm by chance going to an exhaust specialist in the next couple of days as my custom system needs a new hanger rubber that they'll be fitting, so may well ask thei rexoperience of this type of conversion.

Do like it a lot :thumbsup:

Thats what I thought, and with the M you've got two pipes so by shutting off either 1, 2 or none you can have three levels :)
 
Spoke to a specialist and he was aware of this mod. Seen it on Porshe before. He was actually neutral on it as neither affecting performance (up or down), just creating more rasp and pops from the system.

His only concern was heat to surrounding components if it was rooted close and suggested shield wrapping it.
 
Sounds interesting and a damn sight cheaper than replacement backboxes!

I contact warren engineering this week, anyone with a 3.0 2003 -2006 need to measure they backboxs , as well as the 2.5. As we do not have measurements yet.

Cars we do have is 3.2m and 3.0 si, so if someone can measure these is would be great so we can get them order altogether.

Up to 9 so far we can 100% order :D
