How are you liking the mod? Did you use the flanges like we talked about?

Wow I am really impressed! It sounds like a super car now. The start up is menacing but when it idles down it sounds slightly grumblier than stock. I would have imagined that removing all this would make this thing stupid loud but it didn't.....its perfect.

Rev's feel a bit smoother and the power is constant. I can't comment on whp gains but it feels nice. I think imma pull the 2 fuses to reset the computer a bit later today

Naw, no new cat back like what I mentioned. I ended up chopping the cats (replaced with straight pipes) and mufflers(extended a pipe with a hanger) off

at idle its just a nicer deeper grumble..bleeping the throttle you def notice it. Exactly what I was looking for, nothing too crazy but def exotic sounding

So for on hwy speeds your gonna hear it when you accelerate, but it settles off nice when your at a steady speed

I'll get a sound clip tomorrow, but it sounds just like WreuroR's clips except for that bit of rasp at the end. I think his car wasn't fully warmed up

I saved a few pounds too! The box that I put the mufflers/cats weighed like 45-50lbs

So what did this cost you for the parts/install? Can you weigh the cats and mufflers for an accurate total?

Install looks good.

Any droning?

The cost came out to $250. Sorry I don't have a scale at my house and I don't feel like taking this box to publix I read here that the muffler weighs 17.5lbs and it feels like each cat weighs 5-6 lbs. So thats where I got the rough estimate.

The install came out great. I just gotta re spray those parts either gray or paint the whole thing black.

About the droning...Like I said earlier it settles off nice. I wouldn't say it drones, its just exhaust noise. If your going through gears your gonna hear the exhaust, which is why people get exhausts.
I've read the reviews on JoeZ's exhuast and it sound exactly how they describe it. It has a great exhuast note and doesn't get overwhelming. Ripping through the gears is like a combination of Jesus and Fergie , my car takes shape of a unicorn!

If you guys heard it I'm positive you'll love it!
