New exhaust: will I damage the engine?
Hello can you please tell me your oppinions on if my setup will be dangerous to the engine?
Is it worth avoiding the cost of porting my wastegate?
Here is what I have:
S5 Tii with rtek 1.7, clean and flowtested stock 550s primaries and ID 725 secondaries.
Other main engine components are stock.
I'm installing the Bonez Turboflo system (downpipe and main cat) and everything else 2.5 inch to a magnaflow 2.5 inlet/outlet straight tru muffler.
I don't want to attempt porting the wastegate myself and its complicated to find a shop to do it all for a good price.
Is this enough drop in back pressure to blow up with stock wastegate?

IF you're keeping a catalytic converter in place you should be okay IMO, but each car and setup responds differently so you'll basically have to put it on and make a couple of runs, paying attention to the boost levels and then make adjustments accordingly.

Like Kevin said, you'll just have to test and see. Btw, welcome back RR!
As far as porting the wastegate goes, it is really incredibly simple. The biggest pain is getting the turbocharger on and off, but it doesn't take too terribly long. After that it's just getting the 13mm bolts off the hotside, grinding the holes larger (not so large that you exceed the diameter of the flapper) and slapping it all back together.
