i put an aeroturbine muffler at the cat and it made the exhaust a lot more quiet. did it mainly for street driving, when i used to drive the car to and from track.

 

Like so:

 

Sucks. My car will ikely never see MRLS unless I get in on a "no sound limit" weekend. There is no muffling an O2 dump lol

 

Money makes the world go 'round. No more so is that the truth than there.

All of the old money fat cats that live around the track cry about the noise, hence the DB limit.

 

i'm glad i've never needed a dump. weeeeee LOL.

i got in on a no-limit event, but it was cancelled due to not enough people. i was bummed. i guess it's a LOT of money to get one of those events done.

 

See golgo13's post. They probably have to pay off the rich people around the track haha.

In reality, the people that built their house NEXT TO A RACETRACK should be told to kick rocks.

 

I'm too lazy to google this, but it might just be a chicken-and-egg problem.

 

1. Mesa Marin Raceway built in the boonies of Bakersfield CA, 1977. i mean boonies. nothing for miles.
2. Mesa Marin closed and sold for development after the owner grew tired of complaints from neighboring home owners , 2005

i hear Laguna Seca is coming close to the same fate.

 

MRLS was built in 1957. Pretty sure it was all by itself at that time as well...

 

absolutely. i just never understood why people would buy near a track, then complain about said track. are they really that ignorant when they buy??

i don't see them moving the airport near my house.

 

Self-entitlement?

 

its the same with all of the northeast tracks these days too. lime rock is 86db, i skipped an event last month that had a 1 hr shutdown in the afternoon due to a wedding at the church a mile away. new york safety track, new jersey motorsports park and the new palmer track are all battling the locals over trying to shut them down.

 

The last time I ran was back in 2011 and I was catless with a Greddy Evo 2 with a Coast Fab mini-muffler bolted onto the tip. Passed sound just fine.

 

I think my biggest problem is actually my muffler. It's about 5-7" in diameter and not very long. Not much of a muffler, really LOL

 

Just wanted to add for future reference in case anybody cares, Road Race Engineering's stealth exhaust is amazing.

With or without cat, passes 90db at MRLS at WOT, NO turndown / laguna pipe needed.

And there was testing done showing that, with the straight through perforated core resonators, it flows better than RSR's (almost straight pipe) exhaust.

First time at Laguna Seca, ran a 1:41.372.
