Had mine installed today finally! Looks awesome, sounds very good (low deep rumble). It's definitely noticeable how much louder it is vs stock...probably nowhere close to some other exhausts, but don't think you'll be tricking your wife into thinking it's stock lol.

When I drove home with the box in the trunk (rear seats lowered), the drone was crazy and just overall loud! Once I got home and got rid of the box and put the seats back up it definitely made a huge difference. Again, you will still know you're driving a car with a modified exhaust. Definitely reasonable though and won't wake the neighbors if you are easy on the throttle (not sure about cold starts in the winter yet).

Keep in mind that I have the 350 so the sounds may differ from what Flash described. I'll update again in 5-600 miles to see if the drone has subsided at all.

Drone should definitely quiet down a bit after a few hundred miles.

 

BTW, the exhaust note from this exhaust in a tunnel at full throttle is AMAZING!

 

Already did it! Sounds great! Edited my original post that includes some pictures (not like you don't already know what it looks like lol).

 

Looks great man. Can you post a sound clip of what it sounds like on a 350?

 

Here are some side shots to show the staggered tips. I'll try to get a video/sound clip soon.

 

Does anyone know if the sound is any different than the dual tanabe exhaust?

 

 

Looks good! Where and how much did you pay for the exhaust?

 

I got it from Touge Tuning in Mississauga. It was $1,200 after taxes (CAD). More expensive than in the US, but after shipping and customs fees from the US it would probably be the same if not cheaper to buy locally.

 

Still waiting for the sound clip man

 

I'd like to hear a is200t sound clip.

 

 

Nope, I heard this sound clip before I bought mine and it does NOT do it justice. It sounds WAYYYY better in person.
