rotted out headers....

[Paul Perreca]

When i bought my car, the guy i bought it off of said he put MAC headers on it, and an H pipe w/ 2 cats, flowing to two flowmasters. Well, to make a long story short, I replaced the header gasket where i thought the exhaust leak was coming from, and nothing, so only to find out it was where the h pipe meets the headers, on both sides lol ANyway, i got new headers, and a straight H pipe, and there is no more exhaust leak, and what i saw when i took the old headers off was a gaping hole a rot hole, and it was nasty and there was no fixing it, unless i welded it, and in that case, just get new headers neway ! The new sound with the headers and H pipe combo, isnt THAT much louder, but it is WAYYYYYYY sweeter, no more exhaust leak ****, feels like the car is like 10 years newer - watch out for like 8 year old MAC headers, they rot out lol

I have similar issues, the previous owner wanted to buy go fast parts and not fix the old, rotted exhaust. So far i've got longtubes and the H, gotta figure out if my catback is salvageable.

the headers were fairly easy compared tot he H pipe, it comes in two peices, so i put each peice on each header, and that middle H part didnt line up right, it slid ove,r but it wasnt straight so i had to take it back off, and put it together at the H off the car, and than put it back on and it didnt line up w/ headers, so i used Porta Power (shop tool, hydralic tool that spreads as you need w/ pumpin) to seperate the tubes enough to get one on, and than seperated more to get the other on, headers were easy, all bolts threaded right in, and this morning i got like over a full turn on each bolt, cuz i knew that they back out when first put on. I had to lose a Hanger on one side of the H pipe cuz it wouldn't fit in, but the other is in, and its pretty stirdy... I couldnt beleive my headers were rotted out, and my car is much better sounding now, but its still not as loud as it should be, maybe my flowmasters are 3 chambers, i duno there is no tail pipes on the car after the mufflers...

Neone know why its not that much louder w/ new straight H??

Man, I have heard like 3 different people in the last month who have had problems with the mac headers. Glad to hear it's running better.
