Same. On my day a Laguna Seca a ZR1 got black flagged due to +90 db's.

GR8WHITE1 is right. I put LT headers with high flow cats on my car with NPP exhaust. It is kind of raspy and loud. If you get a $95 resonated Magnalow X-pipe it fits perfectly in place of the H-pipe in the front pipe of the NPP setup. The exhaust not is smoother and deeper and is quieter than stock with Normal NPP operation. From what I gather it should pick up on power slightly too, but I cant confirm or deny that. I can tell you that it will definitely make it a smoother quieter sound. My car with out it sounded good, but it was loud and raspy when the valves opened up.

Hey 1LE Red Dragon, does the x-pipe reduce or eliminate the rear popping sound during decel?

I really like that popping sound...

I agree,i just love the gurrgle gurrgle growll growll.Once i let off the accelerator and produce the sound, i give just a touch of gas again so i can hear it again,so it's kinda like a two-fer

I ran my 1LE like you are planning for a little while. It should be fine at any track. It was loud, but not LOUD. To my ears not only was it loud, but very annoying. Magnaflow xpipe was the fix for me.

I remember getting passed up the back straight there by a older TransAm car with side dump straight exhaust, it was so loud it hurt, after the 1st time, I lifted the rest of the weekend just to get the noise by faster. Not like I was going to hang with a tube frame, racing slick car anyways.

Find out where they measure sound and back off the throttle or run one gear up until you are clear of the spotter station.

I just built my own version of a mild to wild controller for 1/3 the price and switching between the two is night and day but really only while cruising or under a certain rpm. To the original poster I say do it and after the install take it to a muffler shop and have them weld in a magnaflow resonated x-pipe where the factory H pipe is and you definately shouldn't have a problem. Are you going with cats or cat delete pipes?

My plan is to go with the matching high flow cats from kooks.

When this car passes you on the track it physically hurts your ears, even with a helmet on. If this beast isn't having noise issues then there's not going to be any problems with what we bring.

That is good to know. Thank you. I only brought this up because of the notice when I signed up for the track weekend.
