Had the primary cats gutted couple weeks ago, figured I make a video and update you guys with the new sound. It seriously sounds amazing now! I can’t get enough of it. Unfortunately, most camera mics are unable to capture the true sound. I wish you guys could hear it in person, but this will have to do for now.

Sorry, no red lining, motor was still warming up. I was in the neighborhood anyway, have to keep polite :) Anyway, idling and cruising are little louder than when I only had the Eisenmann and resonator delete. During hard throttle is when you notice the huge difference, it screams…

Only down side is that I’d probably have to keep the rpm low near police. If they wanted, I’m pretty sure they could ticket me, no worries though :biggrin:
If you guys have any questions about this set up or anything else, feel free to ask :)

Enjoy

That's right, so I wont be able to sneak up on anyone lol.
Funny you ask, I've never been through the Detroit-Windsor tunnel :( so maybe a road trip is just what I need!

A little, slight vibrations are mostly during colds starts, drone is tolerable IMO. Then again others could find it annoying, I love it though mmmmmm

Sorry bud, I know Cali is very strict when it comes to heavy modded exhausts :(

Sounds awesome! I would put the resonator back on and deleted the secondary cats! Im hoping that to be my setup soon.

How did u delete the primary cats? gutted or cut and straight pipe?

Sounds great. Did you take out both sets of cats and the res? Also is there a x pipe in there? :cheers:
Thank you :biggrin:
No, secondary cats are intact, only primary are gutted. Resonator is removed and straight piped with the factory H pipe intact :cheers:

Thanks!

Eventually I'll remove the secondary cats as well, but I'll never put the resonator back on LOL I like making noise, childish I know :hihihi: but it puts a smile on my face :)

It really is a great setup, cat-less headers with a good tune make all the difference :biggrin:

I had my local muffler shop GUT the primary cats, with the headers still attached. You have to be careful though, the primary pre-cat o2 sensor is very close. When nearing the gutting process, drills can poke through too quick and hit that sensor. If you have someone do it, just let them know, or have them remove the sensor before hand.
