Hello everyone...

I read about test pipes rattling due to the fact that most lack of the brackets usually used on standard catalyzers to firmly keep everything in place.

Can you point out which test pipes are equipped with brackets etc. in order not to rattle and please point out if CEL light is lit when used.

Thanks a million!

i have helix v2 and they have brackets. Never rattled. I used spark plug defoulers on it and haven't got a cel light yet.

 

Cool! What kind of gains are expected by just adding helix v2 test pipes to a completely stock 350z exhaust line?

 

Do a google products search for test pipe 350Z. Its pretty easy to see which pipes have a mounting bracket.

 

David, thanks for your advice.

Generally I prefer "real life" hints from ppl who actually own the very same products who have the chance to test them on their cars and give some extra feedback (like SuperBlack did).

I am also trying to figure out the real benefits of test pipes over a completely stock Z exhaust line.

 

APS - No rattle/No rasp

 

berk technology makes good test pipes, too bad they're non-resonated and WILL rasp, but a plus on those is they have a built in O2 bung type thing.

 

I have the Helix as well, adn love them
No rattles, no CEL light, and I don't have much of the "rasp" everyone talks about

 

I had Titek test pipes that come w/ brackets and an extra O2 bung.

 

Thanks everyone...

So "rasping" has nothing to do with the brakets right?

Is it just the "resonated" test pipes that do not rasp AT ALL ??

And braket-less test pipes are instead subject to rattles...

Is this accurate?

If i want to keep the original exhaust manifolds... should i buy the 2,25" size test pipes or the more generous 2.5" ??

What is the rule here?

Thanks again for your patience (i am a total noob).

Ciao, Carlo

Helix SS Test Pipes. 6,280 miles. No problems. Knock on wood.

 

Rasp is a side effect of some exhaust mods. Some members hate it, others do not mind.

A resonated test pipe will have less effect on the overall exhaust tone than a non-resonated pipe.

Members have had problems with both bracket and no-bracket pipes. I am not certain that there clear reliability choice.

 

I can honestly say that it was definately a big difference when i put it on my stock car. I'm not the one who "feels" gains after intakes, exhausts, etc... But i really felt some strong pulls higher in the redlines. Best 200 i spent.

 

Cool! I think i will buy the Helix then.. now I just have to find some company that will ship it to me in Italy.

I tried HopUpRacing... (they sell them for 145 USD)

...but they did not reply my email yet!

Any other vendor you may suggest?

Thanks, Carlo

 

i have the helix v2 and it is the worst rasp i have even seen! i have a magnaflow exhaust with fuji y pipe and i am already ordering aam resonated test pipes....

 

it's probably because of your magnaflow. Resonating doesn't make a huge difference. You will still get rasp. Some exhaust are good with test pipes, some are not.

 

Cool

 

i have the fast intentions resonated test pipes with the magnaflow exhaust and it sounds like crap... the magnaflow sounded good until then.... check out some videos of exhaust with test pipes so if you ever change it out it wont sound bad

 

FI Exhaust with FI test pipes. No rasp. Just dead sexiness.

Rasp seems to be a big concern when it comes to exhausts on the Z & G. If you want to run test pipes with a catback and do not want any rasp at all, get the FI Intimidator.
