exhaust bore size

[f0xy]

hey,

ok... i picked up a magnex back box from a member on here (twin 3.5") to replace my current gash magnex oval one...

before i got this new twin backbox i got a different magnex middle section to replace my other one that had a silencer in it, so now i have one without a silencer...

just looking at the bore size of the pipe on this new backbox its alot bigger than the middle section...? will this matter or will the clamp pull it all together?

cheers :approve:

If its alot bigger you will need a reducer to bring it down a bit. If you go to your local exhaust place they will fit it no problems

ok so i let the monkeys at kwik fit loose on my car so sort the joint between the cat and the middle section, and to swap the back-boxes...

they fixed the cat joint then told me the bore of the new backbox dosent match the middle section bore so they cant fit it? they said i need reducers... anyone know where to get these from and do they just fit in or do they have to be welded?

cheers.

im running a custom magnex middle section with no silencer that is 2" and the bore of this other magnex backbox (off a 172) is 2.5", grrr

the monkey at quick fit was saying you can get a piece that sits over the end of the smaller pipe, then theh big pipe slides over this and the clamp is tightened... anyone seen anything like this??? cant seem to find anything of the sort anywhere...

Go to a place that does powerflow exhausts & they'll sort you out.

cheers people, just found out there is a powerflow dealer 1mile from my house, will pop down and see what they can do.

nipped upto a local powerflow dealer today.. they want £40 to get it to fit... although this means they want to modify my middle section by expanding the end of it to make it the right size for the backbox... i dont want the middle section modifiying though incase i want my other backbox back on...

is £40 an average price?

Sounds about right, hour or 2 labour!
