so I just got my zzp down pipe in and first of all holy rasp lol its crazy when it hits 2000rpm it gets crazy raspy lol i need a cherry bomb as well i guess... but did you notice any vibration after you had the pipe on? mine seems to vibrate the entire car lol not like its hitting something just the sound i mean i know the 44'* are loud but im surprised! anyways did you notice anything like that

I noticed everything is much smoother with the new downpipe. Mine is also much raspier, but the Cherry Bomb helps by making that all low. I made a sound clip that'* filtered to help you hear the rumble of the engine, but you can get an idea of how it sounds. There'* no cat, the Cherry Bomb resonator, and a stock muffler.

hey rad I saw you had to do some rewelding on your system to get the cherry bomb in what length did you go with i would prefer to avoid all that ish. also any thoughts as to why its so raspy i mean i feel like its partially just the motor then again my setup is all pieced together i put in the zzp 2.5 down then the resonator was cut out and replaced with straight pipe and then a flow 44 series put in stock location. im just wanting a deeper growl without that damn rasp i mean its really really loud. think a cherry bomb will do it or do i just need to redo the whole thing??

Rasp is common for all V6 engines. You'll get it in the high RPMs because you don't have a V8 as I'm aware. The louder the muffler, the more rasp. My SLO would be so raspy if it didn't have the quiet stock muffler on it. The ZZP 2.5" downpipe is good because it helps quiet the raspiness.

The stock hanger for the middle of the car is just two rubber rings that hold the exhaust up against the car. That'* where I started the resonator. If you start a few millimeters behind where I did mine, you can squeeze this very long resonator right behind that metal bar that I re-welded. It'* possible. I bought the longest resonator they had in stock, but I forget the length. I'll go tomorrow to check, and I'll let you know.

A friend of mine just has a cat and a Magnaflow muffler, and his exhaust is pretty raspy. The best thing to do would be to get any resonator somewhere in the exhaust piping to see if that helps quiet down the noise. A Cherry Bomb may not be necessary, but it is one of the cheapest resonators out there.

yea thats why i was going that direction. and i know there raspy whats odd is that its from 1800 rpm to 2100 and thats it i mean normal up to but in that range its really loud like 1700 would be 1 4 out of 10 on a loud scale and 1800 it goes to a 7 out of 10
big jump. ill get a res soon though sounds like it should do it

If you're getting rasp in that area, a resonator should fix pretty much everything.

from the flowmaster site
This is the most “aggressive” sounding street/strip muffler that Flowmaster offers. If you're looking for attention, this one will get you noticed. The standard 40 series has an “aggressive rumble" and will generally resonate inside the vehicle around 1800-2000 rpm’*, and again at 2400-2600 rpm’*. Constructed of 16 gauge aluminized steel and fully mig-welded for maximum durability

guess thats why lol

They're just kind of letting you know there'* drone? Seems odd. I don't know how attached to that you are, but you could try a Borla F-body muffler. It'* insanely expensive and a risk because it could also be raspy. But it'* freaking Borla!

Great job Rad! Sounds really good.

well i mean it sounds amazing everywhere but at 1800-2100 so i thnk a res will do it. i dont have the cash to shell out for that non sense lol. i imagine part of it is its just a lot of exhaust to go through one muffler most of you guys have the dual set up im trying to keep that velocity high and run a single set up
