Just got the '03 mufflers to replace my '02 mufflers. I was wondering how to install them myself.
Anyone got step by step or DIY instructions?

If its too difficult, i'll just bring it to the dealer.

Thanks

Very, very easy. It's a direct swap.

Two bolts on each side, remove the hangers, swap, and tighten. Should take about a half hour or so

okay so I take the bolts off, take the mufflers out and replace then with the new ones? that's it? Nothing else I need to know or avoid?

Spray lots of WD40 on the nuts before you try to remove them. They're gonna be on there pretty tight.

also you might want to get a new set of washers for the insides of the pipe where it bolts on, mine were all rusted and just chipped apart and fell out when the original muffler came off. they are probably dert cheap though.

berny

and I use a normal wrench to take off the bolts? or will that be impossible and I need a drill?

regular wrench will do. have one to hold the nut on the back with. and spray them down with lube good. bust that KY all over it.

Make sure they share the same bolts & nuts. Because when I installed my HKS mufflers, the bolts & nuts don't fit and I have to run down to Home Depot to get a new one.

berny

so I guess it's a good idea to get new washers and new bolts in that case right?

FWIW, I used all of the hardware that came with the Comptech Exhausts and had zero problems.

ill give you some simple step by step

1. make sure you are physcially capable to crawl under where the exhausts are and able to use your hands. if not then use a jack and jack the rear up maybe an inch

2. make sure the car is cold, in other words dont work on it if the car was just started. if you are coming home from work give the car a couple hours to cool down.

3. wear a long sleeve you dont care too dearly about and as an option wear some form fitted disposable vinyl or latex gloves

4. spray wd-40 on all 4 bolts and all 4 hangers.

5. un bolt the exhaust from the b-pipe, then remove entire muffler with the hangers on them.

6. remove old hangers and insert them on new mufflers, then hang the new muffler first. Then bolt it back on. Work on the other side the same way, make sure you tighten and you are done

what sidemarker said

it'll be nice to have liquid wrench.

im getting my CT exhausts in the mail tomorrow, and i called comptech to see what size the bolts were. he said i needed 4 10x1.5x35 hex-bolts, 8 10mm flat washers, 4 10x1.5 crimp-net nuts. i didnt get crimp-net nuts just got regular nuts, and everything together was $2.15 @ home depot. can't wait to install them

oh yeah liquid wrench will really helpful to have..wd-40 works too if you dont have it

you get the nuts, bolts, and washers in the kit.
