Any drone during normal driving and cruising around?

I imagine the start-up is pretty loud too?

AMG893

Zero Drone.

Cold starts are quite loud. But warm starts are normal.

Let's hear some just revs and really curious how daily driving is in terms of sound alot louder??

AMG893

Sure will put some more vids up. Cold start etc. Revving.

As far as DD, its not THAT much louder than a 2nd Cat Delete on a stock car. (that is what i previously had) .

When i had 2nd cat delete, the sound was great. Then i got the LTH put on with 100Cell Cats. (still had 2nd cat delete), and it was very very loud. Way too much for Daily Driving. Still no drone at motorway speeds, but anything over 2500rpm it was terribly loud. And IMO not in a good way.
Within days, i put the 2nd cats back in, with the LTH & 100C Cats. Sound went nearly back to normal (how it was with just 2nd cat delete)

I am now on the hunt for an Akra cat back. I have found one in Melbourne. I am just trying to negotiate the price with the guy.

All going well, i will have that on, and it will sound perfect.

Nice why the akra not fully happy with the sound?

Phil Chow

That's really informative AMG893! Appreciate it.

I was looking of doing just a 2nd Cat Delete on the car, but, if the LTH w/ HFCs + Stock Catback sound essentially like a 2nd Cat Delete, that's perfect then!

I'd probably be looking at 200CEL Cats too, which I assume will definitely help with the noise too.

AMGonFire: Not that im not happy with the sounds, but i personally love the sound of the Akra mufflers, and if i can get them at a good price i will do it.

Phil Chow: Yes, 200C Cats will tone it down that little bit more. Its a very similar sound. The only thing i have noticed, is i dont get as much "crackle & pops" on the over run anymore with my current setup.

Phil Chow

Awesome. That's essentially what I want. Hopefully you can take a quick video whenever you have a chance in regards to the cruising and the "noise-level" inside the cabin and what-not.

Really wish there was somebody local to me where I can hear headers on an OEM Catback, haha. Would make it much easier

Sounds good give us a few revs and in car vid if you could would be awesome 😄

Nice! Thanks for posting this is very helpful for all. Great vids to see how fully stock exhaust sounds with headers.

AMG893

No prob. Will have some more vids up soon
