Sorry to hijack but bless you for keeping your car QUIET! It gladdens my heart to see someone preserve the sleeper qualities of these awesome cars while still looking for go-fast options. Besides, this car has one of the most incredible factory exhaust systems I have ever seen.QuikSilver said:Hi everyone- Looking for feedback on Kooks Headers with stock exhaust and how loud is it and how does the performance feel? I'm looking to put on headers but WILL NOT put on the Magnaflows (too loud for this old man!!)
Can anyone give me feedback??
Doyle said:I believe GSM had already posted dynos for Kooks, both with and without the magnaflows. My personal experience over the last week and a half is that the two together are too loud and will start by silencing the interior noise with dynamat. I may look into decreasing the exterior noise at a later time as I understand there are products that are able to do so with minimal power loss. I know your post regards Kooks only, but if they can be silenced inside and out (for the two together) then I guess the only issue left is the cost factor.
Yes it is sound proofing that I have started to look into and have heard good things to this point. I have no idea of the weight, but am not really concerned about it.GNSCOTT said:Is Dynamat some kind of sound proofing? If it is, wouldn't the extra weight you added negate any performance gains? I know the mats on the bottom of My Buick GN weighed around 75lbs. The last thing I would want to do to a 300 is add weight to it.
The weight is negligible compared to the benefit it gives in soundproofing.Doyle said:Yes it is sound proofing that I have started to look into and have heard good things to this point. I have no idea of the weight, but am not really concerned about it.
Thanks for the info, I am defiinitly going to look into it. I think I'll spare her the actual visual trauma though, just the look on her face after I told her the interior was to be removed was plenty.3SRT4ME said:Doyle,
If you haven't purchased already. Consider the www.b-quiet.com line of sound deadening products. I have used several over the years and found this to be my favorite. Less expensive too. I have the b-quiet extreme and V-comp barrier throughout my 3SRT8.
Few moments in life like seeing the expression on your wife's face when you have the interior of your brand new car spread out across the garage floor.
Doyle said:QuikSilver, thanks for the confirmation. Steve, clearly you want to stay all stock right now, best wishes. But it is my ride and I am trying for the best of both worlds here, improved performance without a compromise in comfort. As I understand it, the real benefit of the headers is down the road when other mods become available, so as I stated before, I am not concerned about the weight. Hey if I'm wrong, then I simply tried and I goofed, oh well. By posting my observations I am trying to give a heads up to anyone else who might be unpleasantly surprised by the interior sound.
