installing exhaust today

sunwolf · May 19, 2015, 12:11:29 PM

I am having my friends shop install LME catted downpipes and a magnaflow xpipe today. He just called me and said the opening in the flanges is about half an inch off at the flex pipe end. Is this normal because of the larger diameter pipes? Do they bolt up just fine with no leaks?

I think you should be good,take a look at the pics below which should help,make sure to re-torque those bolts after a couple of hunded of miles. Z

Would love to hear them spool today but the shop called and won't have it ready until tomorrow.

How long has the car been there?did you get a price quote?

It has been there all day. I can't complain too much because he usually does not charge me for labor even though I told him to charge me something for this job since welding is involved.

And now the downpipes are done. X pipe needs to be ordered so I might put that on later.

So after 40 miles the exhaust has started to make this sound like it's vibrating and the two pipes are hitting each other under 8 psi boost Under 40 mph.

I would make sure they used the bolts that came with the DP,and as mentioned earlier and many other posts to re-torque the bolts due to heat expansure,and use some antiseize . Z

My downpipes didn't come with bolts...

Also there's a heat shield on the downpipe closest to the passenger side that I had to bend back a little because it was vibrating against the downpipe. I'd check that too

tell us about the sounds etc once you get it straightened out.

problems has to be the heatshield or something simple.

sunwolf · May 20, 2015, 09:22:23 AM

I think it is something simple. It sounds like a medium pitch humming that only occurs at specific boost and speed levels. The pitch isn't right for me to call it drone but that's kinda the idea I have of it.

Is it a "whine" type sound from driver side?
