Exhaust diagram or explanation

cjwsrt6

Good afternoon, noob here, I have a top speed cat back which is just an hks clone, looking to see if anyone has a shot under the car with a list of what each part is. Reason being, the larger cylinders that are just above the rear cross member I'm going to replace. I thought they where the resonators but can't seem to find anything.
Could anyone assist a big dummy with this

Those are resonators.

Doesn't this 'high-end manufacturer/supplier' include a parts list with instructions?

Exhaust is two years old so I don't have anything like that, but thanks for the help
OhioYJ, thank you, thants what I thought but just wanted to be sure.
Thanks for the quick help

I'm guessing if I remove he resonators completely it would drone quiet a bit

You'll hear more done, rasp, pops and cracks.

The point of the resonators to quiet it down and prevent some drone, without noticeably affecting power. The real question is do you still have the factory cats? If you do, you'll probably be fine to remove them. I'm assuming you are thinking of removing them because it's not as loud as you'd like?

That being said, everyone's tolerance level for loud exhaust is going to be a bit different. Personally I think people who complain about drone in these cars has never owned a car that really drones. My Mustangs droned, especially on any car with an H-pipe, X-pipes helped quite a bit. When I think of a drone, it's more of resonance frequency inside the cabin thats to the point that almost hurts. My 370Z I ordered Fast Intention exhaust, no resonators (one of the biggest reasons I chose FI originally was this option), and have Berk HFC. The car loud when you accelerate, but when you cruise it's fine in my opinion. I can have a conversation, listen to the radio, etc.

The car will be louder when you put aftermarket exhaust on it, the closer you make it to a straight pipe, the louder it will be. You either want a loud car, or something that's quiet for road trips. You can't have your cake and eat it too.

That's what I'm looking for is the knoledge. My srt-6 had muffler and resonator delete and drone but it didn't bother me

I have z1 test pipes
Issue I'm having is the resonator sounds like the inside is rattling so I'm looking to fix it

OhioYJ

You'll still have the resonators and mufflers at the end. I don't think my car is obnoxious at all honestly, with no resonators, just the high flow cats, and the regular mufflers Fast Intentions uses.



There isn't any rasp on my car, but I still have cats. Worst case, you can get new resonators if you absolutely hate it, but from the sounds of you've had loud cars before, and aren't expecting something super quiet like some of the people who complain after swapping exhaust systems... I think you'll be fine.

If you're hearing rattling with your exhaust, the first question is did you remove the emission canister shield when you installed it?

The issue only started last week after 2 years, I haven't gotten it on my trailer yet to look under but I did jack it up and found it's the resonator making the noise
