Hi folks,
Before I get a ban from the Forum
I want to say that everything started just as a game with extra parts I had in garage but at the end it worked and pretty well though
I just installed the axleback Borla S-Type. I love them but during the cold start, they are quite heavy and honestly I was feeling bad for all my neighbors and their kids when I was leaving at 5 am for work.
Anyways the stock exhaust too were pretty annoying at cold start.
My ride has the exhaust dual tip non NPP; however I read that also who has the NPP has the same problem since during a cold start, the valves stay open for the first seconds.
so, here is what I have made:
Cold Start with S-Type
Cold Start with the 'boxes of shame' 
the Videos are taken from the same distance, I just zoomed a little more on the first one.
As you can hear, these crappy boxes do their job, and I have to say, they are quieter than the stock exhaust I had!
I've put at the end of the post the pictures on what it's inside the boxes.
I know
, foam, cardboard and plastic are not really a good idea when we talk about exhaust but I wanted to test first if the idea I had in mind was actually working (I don't trust myself
).
In addition, I'm going to use them only for a cold start, the gases are not so hot to damage something there. I'm just worried about the condensation and the chemicals that may damage the foam in a long term process.
worst case scenario I will build a new couple, 96c the box, $9 pipes and $5 the foam sheets
in case of quad tips, the box layout will change but I guess it will work anyways.
thoughts? Can I still stay in the forum after sharing how crazy I am?
