i never found out the difference between the two... i see people say they have a catback exhaust with test pipes.. and straight piped. Can someone clear this up for me ? thanks

 

Test pipe= straigh pipe essentially. Just some Test pipes have resonators

 

Thank you ShanesG
So does that mean you can get unresonated test pipes
and if i want to do that for my G, should i get Aftermarket test pipes without resonators or just modify my existing pipes? Thanks again

 

Test Pipes are either resonated or non-resonated. No you can't just modify your existing OEM cats. I recommend resonated TPs otherwise you'll very likely have a ton of rasp (amount depends on the rest of your exhaust setup). Also I would suggesting looking into Motordyne ART pipes, they over better performance than Test Pipes.

 

okay well I'm running Nismo CAI, Motodrome plenium spacer, Stillen headers and High flows, Stillen Catback, will the Motordyne ART pipes help with a lower, but considerably louder sound... also considering changing Y pipe and mid pipe any suggestions there.... Thanks for all the help guys !

 

Quieter at low throttle positions and louder at high throttle positions.

And yes, it clearly has a deeper tone to it.

 

I always thought of test pipes as Marcus described them, either resonated or non resonated. Straight pipes to me, means removing every resonator/muffler from your exhaust system. It's just a crappy and disgustingly ugly exhaust sound with tons of rasp and usually a significant loss of power.

 

Stillen headers and High flows, Stillen Catback .......................Those three items = Rasp ,Rasp & more Rasp, so much rasp that you'll need a "Rasperater"....LOL

The fix is easy though , Trust me bro ! I know cause I run the same set up with the exception of the Art pipes....but I used to run ur same exact set up and I got rid o all the rasp , Ur siht will be deep!


R u a coupe or sedan ?

 

LMAO thanks bro yea i know its a coupe ... so whats your current setup ?

 

I'm literally in my RV going out of town. call me and I can give you the information verbally or you have to wait for a while until I can get back to my laptop in about a week and a half and post the links for you my name is bill in my phone numbers 8187306013

 

just too funny

 

Ok the short and sweet.
kill the two Stillen resonators replace with Magna flow resonated x pipipe. Kill Stillen mufflers replace with Magna flow. At the beach With the baby. Ill try to get u more info later. Ill try to post links with my android phone. Kinda hard sometimes. .ill do my best but honestly it would be easer if u called me.
with 03 exhaust items your coupe is probably the raspest is coupe this side of the colorado rockies

 

To clarify further
Straight pipes = Testpipes
Resonated Testipes = Testpipes with Resonator
HFC (High flow Cats) = Testpipes with a higher flowing Catalytic converter

Lastly, we have ours
ARK HFC = A HFC + Chamber = No hiss or rasp with any exhaust.

 

There's lots of links on driver this is just 1 of them that I found. the rasp is terrible I've seen 350z's that sound like ***** . The Magna flow is your answer . You'll be happy.trust
androids suck ....ill post link in next post
