Bradan F355 2.7 Y-pipe

Don't see the cat to make them street legal.

 

This is going to sound harsh, but you need a better camera or a better welder to charge 1300 bucks for a y pipe. That merge needs to look more like this:

What's happening at just shy of 4000rpm when the hp/torque curves show a blip?

Is that the opening of the bypass valve, or is it a changeover in the fuel mapping from "closed loop" to "open loop"?

Just curious, thanks.

Now that's a clean weld !

Are you making any 355 headers ?

I would love a Y pipe, dont realy care if the welds are not Audi standards either as long as its priced right.
But there is no chance ever that i could justyfy $1300 for somthing as simple looking as they seem.1300 is the cost of two complete exhaust systems for any other normal road car.
Now i recon some one who makes one for less than $500, will have them flying of the shelf.

 

Likely the exhaust bypass valve. It opens right around there...depending on gear according to the WSM. (workshop manual)

 

Thanks!

Those aren't my welds, just pics I found on the webs. I can weld like that though.

 

SS is pretty easy to weld and keep a nice clean bead, aluminum pisses me off sometimes though.
