i have a muffler delete, but im wondering how much sound i will gain from Catless DPs and if i should just straight pipe it out. I am going to leave my second cats and resonator for now but can someone give me a example of the change is sound?

Check out my thread / videos to find out.
Straight pipe is really loud! If you do DP's and leave stock secondary cats you will be pleased, but no fire from the back of your car.
Doing cat delete, but replacing secondary with something like Vibrant resonators would net you very loud exhaust but still acceptable drone levels and if you are careful, your neighbors might not hate you too much

I have more clips somewhere, so if you want more data points, hit me up. Just remember, video will never give you true representation of how loud straight pipe can be. Enough to say, people on the motorway were flashing me up as if my car was broken while I was doing steady 75MPH ...
Good fun and exiting for the first 1000 miles, but then it gets to you, especially if you want to daily your car as I do

If you're trying to make it louder, why not add performance at the same time?

Deleting the mufflers does nothing for power and costs money, downpipes cost money and add power. Seems obvious which is better.

If you straight pipe it through it's going to sound loud where on cold start you're gonna turn a lot of heads but also piss your neighbors off.

I have an E92 with catls dp and muffler flap open, sounds great with great performance. Cold start loud deleter is available with MHD flasher and highly recommended.

You are talking about more sound vs extreme sound.

I'd go with catless downpipes first.

If you want more sound then add PE mufflers or 335is mufflers w/ the flap open.

If you still want more sound, then take the secondary cats out.

If you can't stand the the fumes at stoplight and the drone on the hwy and rasp while you accelerate, then add Vibrant 1790-2 Resonators and HF secondary cats w/ a 200 cell count.

If you want to go all out, yep, straight pipe it all the back from the turbos, but don't say I didn't tell ya! It's gonna be loud as hades.....
