Opinions on Kook's 3" catback system...

First, I'm a "keep it mostly stock" if at all possible kind of guy and value the warranty I paid for. I ran through my "mod for power" days back when I was a lot younger. But the stock exhaust is completely too tame for a car like this.

With that said, catback exhuast is one of those things like wheels...what's the real likelihood of a warranty issue being the catback? My goal is to have a nice sounding exhaust that's not hacky and loud. Mellow/deep growl is the goal.

I've narrowed it down to a couple of choices, although I haven't actually heard one of the systems in person, only on different videos.

I've actually heard a Corsa, and it sounds real good, albeit a tad raspy at times. I like the idea of no drone. However, the Kook's system sounds deep and mellow, and doesn't seem at all obnoxious. So I'm leaning in that direction. But I'm not sure about any drone issues. Haven't heard any, so I'm asking.

Opinions, good or bad, accepted here.

As you can see in my sig, I have Kooks LT 1 7/8" headers w/hi flow cats, SLP Loudmouth II axle back. I kept the stock mid pipe. It has a real low rumble and very little drone. It sounds like a muscle car should, not raspy.

I have LT's and The Kooks 2.5 inch Street Sleeper exhaust. It is very nice. It gives the car just the right note.

Keep in mind I have LT's but they still sound awsome.

Actually the KOOKS 3" is known to have drone.....but I don't think you can get the 3" system without headers. I'm pretty sure the 3" system has a 3" inlet which will not work with the factory mid-pipes.

Their 2.5" system should work though.

One other option if you don't plan to keep your factory exhaust is to go have a local muffler shop do a muffler delete for you. They typically run around $100 give or take some. If you don't like if for some reason you aren't out much money. However, the muffler delete sounds alot better than you would think. I had one until I got headers and then went with the 3" Magnaflow.

Not trying to be a smart azz here, but for the 6515 catback system, it says this:

Quote:
Kooks is excited to release this new 3" catback exhaust for the 2010 Chevy Camaro SS. This new system is mandrel bent from 3" all 304 stainless steel and fabricated to the same high quality as Kooks header systems. This system includes a high flow X-pipe and gets it unique sound with two straight through, polished, Kooks specific mufflers. They system ends with two great looking double wall 4" tips.

Note: This system does not includes cataytic converters pictured. It connects to your stock manifolds behind you factory cats, at the stock 2.5" clamp.
So I'm not sure exactly. I'm assuming it'd bolt up. There's SO many systems out there, and I haven't been able to listen to them all in person, which is what I prefer. Not really lookng to hack my current exhaust, just simply replace it with one that's mellow but has a nice, grumbly tone to it.

Thanks for the advice so far anyway, everyone. I'm keeping my options open.

I just heard some vid clips with some decent headphones...it sure DOES sound good. Doesn't sound raspy from what I can tell. I kinda hate the raspy parts of some of the exhausts. Wish I could hear them all on an actual car, though.

But one thing I CAN tell you...what's really annoying, out of over 75% of the video clips of exhausts I just watched, the mofos doing the videos are too fuggin lazy to edit out their azzes playing with the camera, then walking to the car and getting in which wastes a good 15 seconds to start the vids,...and waste another 15 seconds walking out. And with some videos running right about a minute, that's 50% of the video thrown away.

I appreciate the time for making the vid, but for cripes sake, EDIT! JMO.

For MBRP, the 3" S7024304 shows for L99 round tips for the better 304 stainless and they come polished. About $850 is the range for the 409 stainless. It appears many places have the 304 systems for $1103.78 with free shipping. It is comparitively priced.

SLP Loudmouth IIs sound pretty good, but they're axleback. I was hoping for a complete catback setup. They have the rest of the pipes, but sold separate. Which is also about 100 bucks more total. Grrr. My goal is simply bolt on, so in the event I want to go back stock, I can do it without issue.

Option overload...I guess that's a good thing.

Sounds like KOOKS added a 3" that will bolt up now. That wasn't the case about 3 or 4 mths ago. I don't pay as much attention to the exhaust stuff once I went to headers.

There are tons of exhaust systems out there and it is very hard to choose. One that I always thought sounded good but is a little pricey and I don't know that it can hook to factory mid-pipes yet is the one from LG Motorsports. If I could've afforded it I probably would've gone with them.

if your just doing a cat-back, 3 inch is not really necessary.

Borla S-type or Touring exhaust would be a good one also. not raspy like the ATAK or as loud as Corsa, but has a deep mellow tone. the S-type is louder than Touring. S-type is sometimes called sport or stinger, but all the same.

i would not recommend Magnaflow anymore to anyone.
