Weird Exhaust Sound

tommyboy · March 24th, 2007, 07:36 PM

I'm attaching a crappy video, but it should be sufficient to hear the sound...i got in my car this morning and it sounded wrong...any ideas on what it might be from the clip? i have MAC LT headers, MAC no cat prochamber, and MAC axle back....any insight would be great

thanks alot!

Cant really tell from the video , sounded fine, like a no restriction exhaust to me. Maybe an exhaust leak but I dont think so.

tommyboy · March 24th, 2007, 08:03 PM

ya the vid does kinda suck...it just doesnt sound normal to me...i guess ill just have to take it in

Sounded fine?

I seriously doubt if you have a leak.

That's an easy sound to identify and it don't sound like that.

hey tommyboy, can you get any more vids of the exhaust? Revving, Driveby @ full throttle, etc? Im thinking of going to Mac, but need a good video to base it off of. I have the longtubes as well...

tommyboy · March 25th, 2007, 10:44 AM

sure can...ill post em up here later today

Sounds like an exhaust leak to me. The way it popped and the idle.

it's vertually impossible to tell just by a video, but i would say possibly a leak also.

on you tube theres a clip w/mac axle back w/the bassani x and headers. if you search mac exhauast demo it should come up, theres three or so

Did you shut off the second O2 sensor when you removed the cats?

tommyboy · March 25th, 2007, 01:27 PM

yes, the o2 sensor is shut off...i have had the exhaust for about 2 months, and it always sounded awesome, then all of a sudden this. i looked under the car today and realized that there is 1 clamp missing on the drivers side just under the door before the pipes come together, and the one on the passenger side looks broken. im thinkin maybe thats it

Sounds like exhaust leak, check collector gaskets.

gills99stang · April 7th, 2007, 12:15 PM

The prochamber came detached from one of the headers... that's what was causing the sound...

tommyboy · April 8th, 2007, 08:54 AM
