What are the best headers. Ive seen the slp headers for zzp but no real info on how to go after that. I have a n/a monte and lookin to upgrade the whole exhaust system. But alot of conflicting information out there. Thinkin slp headers, zzp downpipe, high flow cat aswell as 2.5" cat back. Maybe magnaflow or flowmatlster. Has anyone else dome this? Could give me some idea of what to expect?
No need for custom downpipe with these either. Bolts right up to catback system. Keep in mind there's no cat in these so if you have strict emission testing to pass you won't with these. If that's not an issue then you're good to go. I also deleted the EGR by ordering EGR block off plates from ZZP.
I have Speed Daddy headers.. Got them from eBay for less than $200 shipped so you really can't beat the price. Almost exactly the same as SLP headers. Install wasn't too bad either. Can't find them on eBay anymore, not sure why though.

. I should have went that direction and I regret it to this day.

There's really no point of deleting the EGR unless you're looking to keep things cleaner, and if you do delete it, it should be tuned out, I've heard of people actually losing 2-3 mpg also with the delete
I am catless also, as far as the egr block off plate don't waste your money. Take the old egr and cut the tubes then take the mounting plates off of the egr tubes put black rvt on both sides of a penny set the penny on the egr tube and bolt it.Back on. Way cheaper and works perfect. This is how mine is done
