part of the exhaust. Just after the headers but before the ypipe/midpipe/muffler

 

Thanks. Can someone send me a link of where I can buy get a good deal for the high flow cats?

 

check some vendors on the Marketplace.

 

Buy them straight from Crawford (www.crawfordzcar.com), Doug's customer service is unsurpassed. - OR - if you want a deal on used ones, check the classifieds on here and my350z.com.

 

Thanks for the link but, I read that I will not need Hi-flow cats if I install test pipes. Is that true?

 

You can only have one or the other.. make up your mind first. Test pipes are more free-flowing and not to mention cheaper, but if you have a 2004.5+ you'll have to deal with bypassing the SES light too and the sound isn't for everyone...

 

1) MREV - 600
2) Test Pipes - 400
3) Exhaust (Stillen, shown with most gains) - 900-100

Those, will get you the gains you want....

Hi-flow cats, are just that, high flowing catalytic converters. Test pipes, are better than hi-flows because there is NO restriction whatsoever, just a pipe. The downside to that, is that they come with some small rasp in the exhaust sound, given that you get the resonated ones that minimize the rasp as much as possible. If you want 30-40 whp gains, get what I said in my list....not much else you can do...

 

Stillen or Injen exhaust with test pipes is suicidal to listen to for more than 10 minutes, but what do I know. Get headers instead of an exhaust, you don't need an exhaust unless you go FI. The stock headers and cats are the biggest bottlenecks in the exhaust system.

 

Start with the MotorDyne MREV $537......Stillen CAI
with Z-tube $200......Cat-back system try to find one
used that'll save you some $. LOL

 

Or that....go with the strup, cheapest and best quality (from what Ive heard) and easiest to install....

 

Yup, Strup are pretty popular among the 350z guys. I don't have any personal experience, but it's definitely something to look into for that kind of money.

 

What's juice? I prefer grape drink

 

I'd prefer to have and quench the thirst of twinturbos with 93 octane juice!

As I continue to shop I found a pretty good deal for ICHBIA test pipe w/high flow cats for ($205.00) and ICHIBA headers for ($321.00). Anybody know anything about the quality of these parts of this manufacturer ICHIBA?

 

Stick with the name that people already used and tried. Go check the Review section.

 

If you want to save some money on headers and want quality and a good reputation then try DC Sports. I have had their ceramic coated headers on my sedan and now my coupe. They only cost around $400 and are a much easier to install then Crawford. I have had no issues with my DC's
