So I am thinking give the 435 a quad exhaust mod which makes it more aggressive and more like a M4.

I have asked several body shops and it mostly requires a change of diffuser and the whole exhaust systems. Which is kinda expensive considering my budget.
Is there anybody here who have done it before and may give some suggestion on the work?

I am currently having the M performance exhaust from the dealer. So I might have to sell it too to make up for the cost.

Thanks

Update:
So after asking all kinda body shops and people. I think the current best option will be:

Switching from my current M performance exhaust to a super sprint one. Link: http://supersprint.us/p-4915-supersp...w-f30-f31.aspx
Switching my current diffuser to a JL motoring diffuser. Link: http://www.jl-motoring.com/BMW_F32_M...p/bmdi3225.htm

This will be the best options considering my affordability. And I have to sell my current exhaust to do it. So do you guys think is it worth doing it?

Here is a picture of my current rear.

That's what I thought. but the original diffuser has only two narrow exits for the exhaust.

Correct. Even if the quad tips are only 3" wide you have to widen the stock diffuser at the cut outs. The lowest cuts have to be done at Meisterschaft or Super Sprint mufflers but they're quiet expensive.
If you want the real deal, buy a kit like this here from Bastuck, stainless steel, tips are 4.5", ABS diffusor and additional center silencer muffler for German street laws. Into the US you could also use a straight tube

Get the REMUS quad, it comes with templates you can use to cut your original diffuser

Yeah it is just I have troubles finding a good diffuser that supports the quad tip. And which brand should I consider for the tips?

No, you're wrong, therefore I'd mentioned the Bastuck set. This is original manufactured and fits a 435i.
