i recently purchased a Z and it has the cat deleted b/c it has a straight pipe.(but stock exhaust).... can anyone tell me about this Modification,,? I dont really know too much about it but, i dont necessarily like it..... i like my Z to be as stock as posssible besides the rim's.. thnaks,,, how could i get rid of this and whats the stock pipe called...thanks

 

The catalytic converters were replaced with straight test pipes. I have the same setup and really like it. Eventually, I will add an aftermarket exhaust system. If you want to go back to stock, look for someone who is selling the cats and brackets, preferably in your area since the item is somewhat heavy and a little large.

 

Here are the test pipes:



This is what it replaced (the cats):

 

I am all about HP and all but i just want the original Z purr upon acceleration... would this be a tough job to swap out...

 

Check the local forum for catalytic converters for sale. New ones are cost prohibitive.

 

How's the change in sound going from cats to test pipes?

 

Sounds the same when idling, even when driving normally. It's when you hit it that the sound gets louder. You only hear the pipes between 3000-4000 rpm.

 

I love the way my test pipes sound along with my nismo exhaust... really makes a nice tone at around 3800 rpm

 

i have some cats and stock y pipe for sale. Let me know if your interested.

for the install, if you have all the tools needed, you can do it in 2-3hrs with a little help. Theres several install threads out here, just search.

 

+2. sweetest sound for this near stock combo

 

Hotness. Time to look into that, too. Any recommendations about where to acquire test pipes would be appreciated (and I'm about to do a search, too, I was just already replying to this. )
