I have a Heffner exhaust coming.

Is it a difficult job to fit. Would I be right in assuming the huge silencer will be replaced with pipes?

Thanks

Yes, it replaces the big can.

Definitely get a buddy to help. The hardest part is lifting out the exhaust without hitting any of the painted surfaces. I made the mistake of trying myself without a lift. Otherwise, it's relatively straightforward. I did not take the clamshell off, just the bumper.

not a hard job .. done it a few times. Buy more painters tape then you think you will need ... then buy two more cases of it ... tape up everything and then have a buddy help you take off the clam. Work over the rear. Easy job... just take your time.

if having an issue call Jason. Great guy and would have no problem talking you through it. If you can't catch him call Shadowman.... he's also a great guy (large understatement there) and has walked me more than just a few turns of the wrench. If you can't get either one of them ... call me and we can both laugh at it all ... :wink

Thanks Guys.....I note one says remove the clam the other did the job with it in place. Will there be an issue lining the clam up again after if I take it off?

I respect different methods of going about these tasks, but I would NOT recommend removing the clamshell. Other than slightly improved access, it really provides you no interference improvement in removing the OEM muffler.

Note that clamshell alignment is NOT an issue if you choose to remove/re-install it (by pulling the hige pins) but I just don't like the liability of taking it on/off as well as storing it - when there's really no need in the first place.

If you have another person to help, removing/replacing the clam shell is a 5 min job. I would definitely recommend it when removing the stock exhaust.

I agree the storage of the shell and its safety is paramount. But, I remove the clam just about anytime that I have anything to do in the engine compartment. I found the ease of access decreases the chance that I might nick something somewhere else.

I can not state this clear enough .... tape everything!!! even if you don't think you'd even be close to it ... an ounce of insurance is worth a TON of cure.

This is very important, I have a Heffner pipe also. Check Accufab website, they mention that some stock mufflers may require taking a bolt out and dropping the transaxle a little. Mine was very very tight and I wish I had known about this before hand.

Maybe someone else has experienced this also.

As shared by many the process is not terribly difficult

Use plenty of tape and I also use a couple moving style blankets when lifting the OEM unit out.

The only thing that I wouild add at this time is with regards to the OEM cats; generally I find that by loosening the nuts securing them it makes the aligning of the cat back unit much easier. These nuts are easy to access.

Yes, writing a check is often easier than turning a wrench and when you have experienced hands nearby it is a smart choice.
