If this helps I have fabspeed mufflers and cats with suncoast headers. I ran with just the mufflers for a while and thought they were a little on the quiet side. Then I ran muffler bypass pipes which were way to loud for the street imo. With the setup I have now I think the sound is perfect as well as the overall volume perhaps a bit more to the to loud side but I love it.

 

hmmm...good thought. Thanks for the tip, I'll check it out.

 

Not if you use an accurate sound pressure level meter.

Then you know the exact levels for every change or modification.

In 1975 I was the first to work with the CHP to establish noise standards or SPL ratings for accessory exhaust systems.

It's done with the same parameters all the time. No subjectivity. You get accurate answers!

 

would you post video of you car.

 

if someone can tell me how I can do that later today.

 

downloas it to your PC then upload it in youtube.com

 

Thanks, I can do it a little later tonight. Any special requests as far as rpm or revs?

 

What system are you running now?

 

I think mufflers and cats with suncoast headers

 

Sorry guys I had a very late night last night. I will have the video up for sure by this afternoon.

 

I have Fabspeed cold air intake, Fabspeed cats,mufflers and Suncoast headers.

 

I am not familiar with the Suncoast Headers, are these X51 or are these there own?

 

They are both they are fabricated by Suncoast but they say they are duplicates of the x51 headers.

 

By the way I'm having trouble uploading the video to my mac and pc.

 

I would bet that they are less then the Porsche OEM, other wise no one would buy them.
