I currently have a 03 z with Injen Cold Air Intake , ground wires, UR pully set, Injen ses straight tip exaust. I am really wanting to remove my cats, but idk what to do. I dont want to have a really raspy sound. I dont really know what all is out there, or how much it costs. I was planning on putting some test pipes that were around $160-$180... Thanks for your help

I have the R/T High Flow Cats. They are street legal compared to straight pipes. No Rasp at all. But they are not around $160-180. I do not know what is out there for that price.

Crawford are nice but way to expensive for the same gains as any other high flow or test pipe. I would either go with kinetix resonated test pipes or wait for the ones from unlimited tuning.

The R/t Cats are the highest flowing next to a straight pipe. Plus they are street legal and you wont get the burning gas smell from race pipes.

But they are way expensive too. Its hard to find a place that sells them now because of the inside of the cats collapsing issue and they are very raspy too. I should know because I used to own them. I am so much happier with my Kinetix resonated test pipes. They are almost half the cost of the R/T's and flow even better and have zero rasp.

Thanks it sounds like i need to go with the kinetix resonated test pipes. The pipes I was looking at are the Helix cat-delete pipes (http://www.i-m-racing.com/hecatepi35g3.html) if that helps. I know that they are illegal, but where i live we dont have any emmisions testing.

Stay away from the Helix if you dont want rasp. Any normal test pipes that arent resonated will be raspy as ****.

Ive heard that some would make it really raspy, and that people were selling them because of it. So i bet these are the one's they were talking about. How much do the kinetix resonated test pipes cost?

You might want to check that again. The R/T Cats outflow Kinetix, there is a chart floating around that shows that race pipes are the highest flowing, then R/T cats second. I am using the Fujitsubo exhaust and I have NO rasp at all with these Cats. I am Very happy with them.

The resonated kinetix are race pipes. There is no honeycomb in the middle of them. Just a straight pipe with a resonator welded around them so I dont see why R/T would flow better. Maybe the Kinetix high flows may not flow as well... I have just seen way too many failures with the R/T's. I have personally seen at least 20 R/T failures on these boards. Performance Nissan stopped selling them even because of this and they are also known to be very raspy even though yours may not be.

$650 for high flow cats is a lot. (I got mine used for a good price)

I stayed away from straight pipes since I did not want the fuel or sulfer smell. Plus, I wanted to be legal and not get busted for running a straight pipe. For the $500 I paid, Just seems safer.

I have the straight test pipes and like them. I don't care about the raspy sound since it sounds really loud when I get on it. Besides, it sounds like a Ferrari. I got them for $169 from Hopup Racing and installed them myself. :thumbsup:

I have been thinking about getting the Kinetix plenum. But I heard where someone's cracked. Is that a design flaw where the plastic just cannot stand up to all the heat?

The earlier verisons of the Kinetix plenum (V1-V3) had lots of issues with cracking. So far there have been no reported problems with the V4. Dave (Dave079) has a V4 and loves it

The cracking had to do basically with where two of the bolts were placed right in the middle in the plenum. The plenum flexes when when the accelerator is pressed and puts stress on the plenum where the bolts were causing it to weaken.The V4 did away with thse two bolts. The V4's have been out for months now and none have cracked yet. I have had mine for about 3 months and would definately recommend it
