Help: exhaust tips alignment issue
 
As you can see from the pics attached, the passenger side exhaust tip is not straight.
I have seen the threads with motor mounts as suspect but the passenger side one is not hanging lower than driver side. its more of a horizontal alignment issue.
I have not yet taken the bumper off to check the muffler hangars/bolts.

Car has the PSE

any suggestions?

top view, passenger side seems off

Motor mounts are easy to swap and inspect for sag. Need to narrow potential issue and that's where I would start.

It looks like its drooping down and outward. If motor mounts are good...... I dunno?

Are you saying that after adjusting the tips (i.e. loosening the bolt and then manipulating the swivel/pivot angle) you cannot get the gap and alignment to match on both sides?

If yes; then it is almost certainly motor mounts.

yes i played around with tip adjustment with no luck.

I guess time to buy RSS motor mounts, though i was hoping the muffler would have some adjustment as well after removing the bumper and taking a look there next weekend

I know of no adjustment you can make on the muffler mounting that will change anything significantly. Were you able to completely remove the tips?? I initially thought mine would not move much until I removed them and cleaned up accumulated corrosion, soot and road debris. You should have a pretty wide range of movement on them. I agree with others input though that you likely need mounts. Someone posted the install specs for these sometime back that I used to correctly position the tips in the rear facia opening after replacing the motor mounts. I searched but can not find it. Maybe someone who recalls that post will help out.

Is this car new to you? Did you get your plugs changed recently? I got mine replaced, and had to replace some exhaust bolts. This slightly affected my tip alignment. I didn't even notice when I got the car back, and now it's kinda bugging me. So that's a possibility.

yes i removed the tips completely and tried adjusting them which made them sit a lot better but not perfect.

I'm just spit ballin' here, but if you're trying to isolate the issue of the motor mounts, then why not eliminate any reference to the tips entirely by simply measuring the distance from the ground to the bottom of the exhaust tip fitting from the muffler side on the right and left sides? If those heights are unequal, then it must be the motor mounts ..... or am I missing something :confused:

dannysf 04-23-2017 06:29 PM

It doesn't seem like the motor mounts would affect the angle. It just seems way off, whereas motor mounts would just cause it to sag and be lower. Doesn't seem like it is the tips either because the tips would naturally want to just move to the angle of the tail pipe as you tighten it. Perhaps some of the cat or muffler piping is not bolted on correctly, causing the tail pipes to actually come out at the wrong angle. Taking it to a muffler shop and getting it on a lift would be best to see what exactly is going on.

If its not a stock exhaust that could be the issue

The tip height left vs right is just off my 2mm which is why I didn't think it was the motor mount as all posts I've seen here there is a bigger drop between left and right pipes if it's motor mounts.

The pic I have taken from top of bumper shows the right side pipe does not come out straight from the bumper almost like as if the pipe is bent and coming out at an angle. Il take th bumper off and inspect everything first before buying new mounts.

Has there been any exhaust mods done? How many miles on the car? Take a pic from the bottom

I'm not sure if this has been your car since day 1 but if I came across a tip that looked like that I'd say someone backed into something.

If x is along the back of the car, y isfrom rear to front and z is the vertical axis, it looks like the rear of your tips are rotated about 10 degrees counter clockwise around the z axis. Have you tried loosening the bolt holding the tips and giving a gentle tap with a rubber mallet on the inboard part of the tip (to try and rotate it in and therefore rotate the outer tip away from the body).

Every picture from underneath I've found (such as this) make it look like they can rotate a bit.
