Exhaust leak effect on performance

Okay two things here

i was bored so after installing my header so me and a friend tried to tackle the rest of the exhaust system, installing my high flow cat, and cherry bomb resonator…and appparently we cannot weld very well…the resut…well my exhaust is about as solid as swiss cheese and it sounds like a helicopter. its leaking in at least 4 places, very small leaks but you can tell they are there.

its going in to get done properly soon, the first attempt was a learning experience and it was also free. SO heres the deal

  1. will a leaky exhaust negatively affect performance badly enough to notice…like when i get it done PROPERLY and not leaking will it go better

  2. the EGR could not be saved so i plugged it on the header, the outlet part that is but as of right now the pipe going into the intake is open to the atmosphere…and around 3500rpm (where the EGR opens apparently) i get this nasty Bog happening, as (i think) the pressure is screwed up from the EGR opening the intake manifold to the atmosphere.

does this make sense? If I plug that tube should it help too

im sick of trying to figure out all the tubes and valves and wires and gizmos…

Haha. That is why you get rid of all that crap. lol The exhaust leak will not hamper performance. Not enough to notice anyways. You would have to completely isolate the EGR from the engine to get rid of the bog out.

Some EGR discussion on KA-T.org that may or may not help you out:

yea they say that you should put a plate in the egr to eliminate it…ive just duct taped mine shut for now at the pipe on the other side of the engine, but i havent run it yet
i wonder if it will do the same thing

for now though the duct tape is fine ill do it right when i have time to dismanltle the intake manifold to get to the egr

thanks for the link!

Duct tape! hahahah thats AWESOME!!

Dude you’re my hero.

LOL

im going to FIX it properly but its a “for now” type thing!!

glad i didnt show you all my stereo wiring or sideskirts!
