Replaced a cracked crossover today and it made the world of difference on how well the truck runs. Seems to warm up quicker as well. I suppose if I had thought it out better I would have known:o:

More exhaust pressure = more boost=more power=more heat

One of the donut gaskets on my crossover is leaking. It is the passenger side. Still builds decent boost, but starting to get bad. I will replace it this summer.

Just remember,
The longer you wait on exhaust problems the worst it will get.

The Turbo rely s on exhaust heat and gasses more than anything else.

Just my 2 cents!

I know, going to college its hard..... SMokes a little under the hood at startup and when in overdrive going with a little throttle i can hear it ticking, making the ol exhaust leak sound....

I understand, I work full time and do college part time.

A down side of a leaking crossover is possible higher exhaust temps because lack of boost.

I thought that mine was just a leaking donut but when I took it in (Too cold to do it myself). They told me it was a cracked crossover. $302.00 later and alls well. (He also told me he broke 4 of the bolts (extra $90.00). It all started as a $60.00 to $80.00 Job:(

YUP!!!!, My truck is sooooooo rusty, i mean like really bad..... So everyjob i do on it is 20x harder, i break everything i take apart. So im thinking they wont be able to get mine apart EASILY, the exhaust system on my truck is sooo rotted it looks like tree roots coming out of the motor. I had a bear of a time putting my 4'' exhaust on. Had to take the hole pass inner and outer fender off to get a sawzall in there to cut the band. I love my truck but it really needs a new motor and body. Frame is in excellent shape tho, dont ask me how, it was ziebarted....
