Heres a sound clip of my Remus exhaust with my berk TP i have. Ever since i put on the TP i have been having this whistle noise, and just wanted to make sure all is normal or should i put the car on a lift and check for leaks? When i first got it put on it didnt make this noise, after about a few hundred miles it then started whistling like this

My mechanic friend just said its just the car breathing


My mods that may be of concern are KN FIPK/Comptech header/Berk TP/Remus Exhaust

Just installed mine today (berk on oem exhaust). I have a similar whistle however it's only under load.

Get a cel yet?

 

i'd check the tightness of all the nuts/bolts, it's easiest to have someone in the car with it on a lift, and then have them bring the engine to the speed when it starts "whistling"

 

no CEL yet! i kinda like the sound, ive just never heard of anyone else having it and im also having a slight loss of power problem right now but im pretty sure thats just a bad map sensor, which is why i was worried about it..

I will check the nuts and such though DFWs2k, thanks for that tip

 

Did you replace the donut gasket and the rear gasket that connects to the exhaust? I have the noise too its right around 2500-4000 under load. It gets annoying.

 

i have the berk tp on my car.
same noise exactly.
tried to check the nuts/bolts it looks fine.
when u drive the car and stop at a light u smell gas?

 

i smell something.. but with a testpipe thats to be expected

I myself, didnt do the install, its the only one i havent done, i was down visiting my dad for a little bit and he's a service manager at a nissan dealership and he was like hey! i can get it put on for you. So i dont know how they slapped it on, im just worried they forgot a gasket or something

Seems like its normal though with all these responses im getting?

 

i don't hear anything out of the ordinary... you're fine...

 

I have also changed all bolts/gaskets and I still have that sound.

It's weird, I actually feel a power loss under 4000 rpm and no noticable increase in power above 4000 (but it's not like you should feel a big increase).

Reset the ECU -- Im still testing it but I might put the cat back on because im not to sure on any gains from this (Stock exhaust).

The lower rpm has a bit more grunt and im hearing a pulsing sound in neutral -- i like it.

 

I think I have a berk tp and I don't ever recall having that sound...
