Hey, I have for sale some new, unused Helix TP's for the 03 and other compatable models 350z/G35. Looking to get $150. PM me your number if you're interested. Thanks.

 

How much did you get these for new?

 

I traded for them, but they go for $159 plus shipping on intense.

 

does it comes with all the hardwares?

 

was wondering can these be installed on the stock exhaust system... if so my number is 703-919-3831

 

can do mang....you might want to research before the thread @$$' start calling you names for not searching.

 

yes sir!

 

bump for flakey-ness.

 

SOLD!! thanks ZZZRated!

 

Put on right after i picked them up from you. they sound alright but have a small rasp on the down rev. but deffently got better throttle. Thanks

 

These exact Test pipes are on craigslist now.

 

I got a complete true dual exhaust pput on my car today so i no longer need them. thats why the same ones are on craiglist for less the price cause they are no longer brand new.

so if any one wants them my cell is 703-919-3831

 

^what type of exhaust did you put on?

 

True Duals With X-pipe and MaxSpeed Mufflers. Sounds pretty good nice and deep. but was too lound of an exhaust with the test pipes on it. you'll hear it at the next cruz bro

 

i guess you got that exhaust set up at rms right?

 

Sounds good tony

RMS sold you a True Dual setup on a stock N/A car? wow.....

 

yes i got it at RMS. is that bad or something?

 

I'm running a TD exhaust on a NA car, in fact many of the exhausts sold for our car are TD. There isn't really any downside to it as long as you have an X-Pipe or an H-pipe. The test pipes would have provided more horsepower then an exhaust, but as you know the test pipes have drawbacks.

 

whats an NA car, and why would it be bad to have the exhaust i have on my car, and why wouldnt of they sold it to me thats what i wanted, as far i can tell its the best way to go. unless you want to turn a duel exhaust car into a single witch looks kind of funny from the rear. and i doubt it give you enough power to make up for the missing tail pipe.

i think it sounds pretty good better than most exhaust i heard on a z. also it deffently has better throtle respose and maybe a little bit more power.

and with the exhaust the test pipes were to loud, so im ordering some high flow cats instead, this is my DD.

 

N/A stands for naturally aspirated, ie, not forced induction.
Some exhausts for our car, including stock and nismo are a single pipe back from the cats to the muffler which goes out to dual exhaust pipes. Many aftermarket exhausts remove the Y-pipe for an X or H-pipe and run duel pipes all the way back to dual mufflers (sometimes they are both container within a single stock looking enclosure) which is known as a true dual exhaust (as opposed to the stock exhaust which is not actually 2 pipes even though there are two exhaust outlets on the rear of the car.)
