ATR Exhaust

[geetee]

Brought a ATR 3" SS exhaust with pitbull mufflers (Old School). Mufflers have surface rust. Check the pictures:

Nice find. That seems like a really nice set up. Every now and then I think about getting the GN1 exhaust like that, but the Mag Tune 3in dual exhaust I got from Conley's Performance Plus back in 1990 still works great as long as we don't start smog testing as the V shaped single inlet dual outlet muffler sits close to where the cat used to sit.

Never seen one with rear exit pipes

Never seen one with rear exit pipes

The tail pipes are not rear exit... just on the wrong sides

Nice find btw!

I was wondering if he meant the single shot side exit in front of the tire?

I have the same exhaust in storage, but no mufflers. Trying to figure out whether to run it or the single shot when I get the car running again.

Did you buy them off Craigslist ?

 

[geetee]

Yes

I run the ATR's on my Conley built car and it sounds good with the cam!

I heard they sound great. Can't wait to get them on my car.

There are a couple of revs at 1:10. Not the best vid in the garage.

 

[geetee]

They have a nice deep throaty sound.

The very first ATR exhaust was a 2-1/4" dual system that exited out the rear (like a Monte SS). You used the factory Y pipe and cut it right where the pipes straightened out after the split. It had 2 short connector pipes to the mufflers, then tailpipes straight out the back. Had it on my car for years. Still have the tailpipes.
