Cantrell headers - RM Racing (B&B) Exhaust

[NSX2398]

There have been a number of post recently about various header & exhaust setups. Here's some video of my Cantrell headers/RM Racing (B&B) exhaust with stock cats on my '91. The exhaust is several years old now but the headers were just installed in May. Videos aren't great but the sound is realistic. And it's my first attempt at Youtube.

When I originally did the exhaust, it was louder than I wanted but tolerable because it toned down at highway speeds. It's probably the boom'iest at about 2000 RPM. After the headers were installed, I was expecting more loudness but I'm sure that it's slightly quieter overall and exactly what I was looking for.

I've tried to provide video from the outside (at rest and driving away) and inside (thru the first 3 gears) and also at various hwy speeds. The objective here was not to get the fastest acceleration but rather to just give an example

Wow thanks for the videos! I was wondering what my RM racing exhaust would sound like with headers.

Not a HUGE difference in sound but that could be a good thing.

I noticed the same thing when I had my DC headers installed...still drones at 2K rpms but quieter overall.

You guys still kept the stock cat in place, correct?

Wonder what it would sound like with that removed...

Hehe sounds almost exactly like mine. I have the same exh, but I just installed some CT headers last month. I was worried it would get louder, but it didn't so I was pleased. :biggrin:

Yes, still have OEM cats. I am considering going with some ProSpeed high flow cats eventually.

I have the Cantrell headers, test pipes and Comptech exhaust and it is a bit louder than i would like. It also drones a little and i don't care for that either. I am told it could quiet it down a bit if i put the cats back on but i just installed all of this so i am in no big hurry and will probably wait until i find an RSR exhaust and then get some high flow cats and install them together.

I have an iphone and i can't talk on it in the cabin with the windows up even a cruising speeds. I am constantly having to ask the person on the other end to yell over my exhaust. I don't know how some of you guys live with the loud super loud stuff.

I use a hands free ear pc. Seems to work fine. Speaker phone is useless. Just have to make sure the windows are rolled up during a call. Otherwise the combo of the wind and car noise does become too much.

I tried the hands free headphone things that come with the iphone and i can hear the other person when i use them but they can't hear me.

I am contemplating adding some additional sound deadening material on the back wall behind the seats but i don't see that helping much since the sound is coming from the exhaust and not really the engine.
