I thought i would share my experience with everyone and hope you guys choose your test pipes wisely. I installed my strup test pipes last week with only 800km on my 07, i started to hear a rattle coming from under my car at certain rpms, the best way to describe it would be the sound of a rattle snake. After going to dealership and a reputable mechanic, they both told me that the cause is most likely the test pipes. When the test pipes are bolted on to the y pipe, the design of the strup tps apparently stretches the y pipe outwards and causing the inside to break down.

Besides the design, i have also noticed that the two 02 holes are the not aligned properly, one of the 02 sensor was slanted downward making it very vulnerable when you go over bumps.

I replaced my tps today with fast intentions resonated tps, and what a difference in quality and sound. It complement the stock exhaust perfectly, i will post a video when i get a chance.

 

Fi Ftw!!!

 

Hey were the Strup resonated? I have to buy another pair of test pipes so I need to make a choice..

The same thing happened to me, I had some resonated test pipes which gave me no problems for a long time but when I installed an aftermarket y-pipe they didn't work well together and the welds cracks on both a coupe of times.

Question: Do you think an H-pipe will be less stress and less prone to craking?

 

i had the test pipes, i don't think strup make resonated test pipes. If the stock y pipes worked for you, maybe you should just stick with your stock. I am not sure about the h-pipe.

 

i never had any issues w/ the stock Y pipe and test pipes-- i know whoever installs it and they bend the y-pipe the wrong way it will crack it beforehand

 

what .... yall guys are worring me now...
i was thinking of getting the strup test pipe
but i saw the TOMEI one's ...
they just bolted it on with eaz but my o2 sencer was a hassle to get off..
i wonder if my y pipe is going to break ? what should i check for in detail?

 

This may be a stupid question, If you have test pipes on your car instead of stock cats or HFC's would you fail state inspection?? I know some states use sniffers to test emmissions.

 

yes you would fail state inspection unless you de bug it ....
i just got the bypassers or some thing and reflash my ecu and no check light
...
if your check light dont come one .. it will pass

 

So either you replaced your Y-pipe or the dealer was lying. I would assume they were lying, but let me know.
