I just got a FVD sports exhaust... but am stuck trying to remove the old stock mufflers.

I have managed to disconnect the muffler from the cat and the tailpipe (just a couple of clamps) but can't see how to unmount the muffer itself. They appear to have two mounting points on the inside (a 'short' and a 'tall' one) - these are where the muffer is attached to the car.

The problem is that the bolts used to mount these will not come out - the bolt appears to be inserted from the top of the bracket - from above the engine and not from underneath. Above the bolts, the boby starts and i can't see how these can be pulled out.

What am I doing wrong? Do I need to remove more from the car - I thought that changing the muffler should be a simple bolt-off/bolt -on job?

Any advice is very welcome at ther moment.

Thanks.

 

There are 3 nuts that hold the muffler bracket, 13mm I think, all can be accessed from below. Also try removing the rear wheel, this will open up more space. The brackets come off with the old mufflers en bloc, they must be transplanted to the aftermarket mufflers.
After you do one side the other will take 20 minutes.

Removal --
1. You will need to lift the car high enough that you can safely get underneath (you do not need to remove the rear wheels on most cars but most folks find it easier with the rear wheels off).
2. Loosen the 2 bolts (each side) on the sleeve that connects to the cats and then slide it towards the cat. (You might want to spray these nuts with WD40 first so they will loosen easier -- just don't spray the O2 sensors).
3. Crawl under the car and remove the 3 bolts that hold the muffler mounting bracket and the muffler in place. These can be a bit of a reach and not much swing room for the wrench.
4. Rotate the muffler down and out from under the car.
5. Remove the tailpipe by loosening the clamp as you will need to use them on the new mufflers.

Install --
1. Attach the tailpipe(s) to the new muffler but do not tighten them yet. You will need to adjust everything later before you tighten them down.
2. Rotate the muffler up and on to the 3 bolts and lightly tighten the nuts.
3. Slide the sleeve off the cat and realign it on the muffler and cat. Again, don't tighten the nuts too tight yet.
4. Align the tailpipe so that there is about 20 mm distance from the top of bumper cover and equal distance and length all the way around. Then tighten down all of the nuts and the tailpipe, cat sleeve, and the muffler bracket.
5. Repeat on the other side and you are done!

 

Thanks - looks like I was trying to just remove the muffer and NOT the mounting bracket.

I'll give it another go later.

 

Ok - I have had a look - where are these three nuts? Is this the plate attached to the engine block opposite the muffers?

Thanks again!

 

That sounds right. The mounting bracket attached to the muffler with the 2 long nuts and bolts attaches to the plate you descibe and the 3 nuts hold it all together. Check out www.p-car.com there is a nice DIY with pics.
