I have Kinetix High Flow Cats, should I want test pipes instead??? If so which ones???

 

don't bother. unless you're unhappy with the hfc, the gains will be minimal from switching to test pipes.

 

Have to say why first.....

 

I have a minor regret buying high-flow flow catalytic converters rather than test pipes. I assumed that I could not pass the emissions test with test pipes. I was wrong.

At this point in my budget, $200 test pipes and putting the high-flow catalytic converters in the trash is not an option.

 

Get the test pipes, i love mine. There is a slight smell from them but its not bad. I only really smell it when im pulling into my garage. The car pulls harder and sounds good. I got them here..http://www.fastintentions.com/350z.htm good luck

 

Did you get resonated tp's or not. Is the sound difference between the two that huge?

* I'm about to add the Magnaflow X pipe to my Injen ses..fyi

 

I got resonated ones. I believe the non resonated ones will sound louder.

 

yes, the non-resonated will sound louder, not dramatically louder though. and the primary difference between the two is the slight rasp you get around 3k rpm's with the non-resonated ones. Strup makes a seriously nice set of non-resonated pipes. We have them on sale with free shipping right now for anyone interested.

Here's a link to our vendor classified sale for more information and pics:

Feel free to shoot me a PM if you have any other questions. Fast easy installation, and fitment is perfect. Get a set of non-fouler plugs at your local auto parts store to keep the CEL extinguished!

 

If you want a good resonated test pipe check ours out, we have dyno numbers and sound clips @

Thanks, Tony

 

Is there an advantage in getting one ( resonated ) over the other ( non-resonated)? How bad is the actual smell? What does it smell like ( ie. gas, BO, a stink bomb).

 

By having the resonator it cuts down rasp. In some applications completely eliminates it. As far as the smell I have never experienced it personally but I have been told it smells like fuel.

 

what the piping diameter?
do you carry any 3.5" downpipes?

 

MMMM..I like the smell of fuel. I'll be placing an order with you guys this week. Thanks for the info.
