Vehicle = 2011 2.7l I-4
I work at a performance shop and have access to aluminum, stainless, tig and mig welders, etc and was wondering if the modern full injected engines still need a bit of backpressure?
My plan was to order LCE headers, cut open the cat converter(s?) , gut em and re weld em on and then dump the exhaust somewhere.
But with the headers, gutted cat and no muffler, i was wondering if that would actually hurt the engine or increase the risk of blowing it up?
Like should i maintain x amount of backpressure or just free it all up?
And also will any of this help without being able to program the ECU?
Cause our ECU's arent flashable or something like that right?
I honestly am just trying to make the lil 4banger sound beefy as can be.
Any help/links/info would be greatly appreciated
