I'm asking everyone here to help me compile an exhaust note thread for the use of others.

I'll have another one monday when my 6'' magnaflow race muffler arrives

Here's a before/after of my exhaust:

Before

Engine: L24/E88, Triple 40DCOE Webers, stock cam

Exhaust system components: stock manifold to 2.5" pipe

Muffler: One straight-through, perforated tube can muffler (not much muffling going on here...)

Video:

After

Engine (same): L24/E88, Triple 40DCOE Webers, stock cam

Exhaust system components: Nissan Motorsports header to two separate 2" pipes

Muffler: Two 18" glasspacks in transmission tunnel and two 12" glasspacks at the end, all reversed.

Videos:

I didn't have much time to get a good video of the new exhaust. I will also get a video of the new twice-pipes in the same format as the "before" video, as I get the time.

Enjoy!

I'm liking this thread! Steve, what diff are you running?

[steve91tt]

Both of my cars are running stock diff's. On my local track neither has enough torque to break the back tires loose in the corners. I ran a tighter track earlier this year and I had to feather the gas on track out so as to not to grenade the R180 in a couple of places.

RATIO is what I was looking for-thanks

[steve91tt]

Sorry but I'm embarrassed to say I don't know the gear ratio. I know that both cars are running the same diff in posts 5 and 7 above because I actually moved the diff from one car to the other (long story). I'm also pretty sure the diff is a stock R180 from a 1973 240Z as the car it came from only had 60 000 miles on it and it appeared to be bone stock when I got it. I think these cars came with a 3.36 ratio with the 4 speed but I could be wrong.

Steve, that onscreen telemetry is awesome!! Where did you get that?

[madkaw]

I kind of figured a 3.54, there wasn't too much variance in the r-180. Watching your gear selection it seems your 2nd gear is good for 70, kind of like my 3.54 with my wide ratio t5. I thought the 3.36 was only in the r200
