So I'm going to be putting on the coupe midpipe in my 06 g35x in the next week or so soon as it arrives from InvincibleG(thanks!). I'm curious, my car has 25k miles, should I replace the two exhaust gaskets while I'm installing it or just resuse the ones there? If you suggest to replace them is there anywhere online to order replacements? I found a few off brand gasket, but no idea which are good and which are bad. Any recommendations?

Thanks!

 

You should replace the gaskets, but it isn't really needed unless you live in a snow belt state. when i replaced my mid-pipe i was simply able to reuse them no problem!

 

any recommendations on where to get them? I tried autozone but they don't carry them. A trip to the dealer would be nice but it's a PITA to get down there.

 

any good muffler shop should have gaskets for our oem exhaust's size

 

i got mine from the dealer. that's probably your best bet. it's a lot quicker than ordering online. the gaskets are cheap so you wouldn't be saving much online anyhow. i believe mine were ~$11 for the set...

 

I've read from other posts that putting a coupe midpipe in a '05-'06 sedan would not yield as much of a noise difference as in the '03-'04 sedan due to the muffler design (I believe). The '03-'04 sedan owners would greatly benefit from adding a coupe midpipe. Do a search in this forum for "coupe midpipe" and you'll find lots of past discussion about it.

There is definitely a difference using the coupe middy on an 05-06. The coupe middy is about 1/4 the size and definitely less restrictive. There is definitely a noise difference, maybe not as much as 03-04 but definitely still a difference.
