two questions about a racing straight pipe
1) Is it worth it?
2) Does it really add 9-16 hp?

 

shhhh its "test pipe" =X .........it depends.....are u talking about the pipe that is the B-pipe without a catalytic convertor?? or u talking about a straight pipe that replaces the y pipe all the way to the muffler??

 

Ah i'm not that sure.. I saw it on ebay it was titled "racing ss converter" or something like that .....

 

if u really want a nice gain.........buy a WSP Y pipe or cattman if you think its better (which its not)......that will give u a gain of around 15 HP..........a cai will add another 12

 

Straight pipe aka test pipe just replaces the cat. convertor. I don't know about 16hp gain. 5hp is more realistic.

 

no, i dont think so.

and NO!!! test pipe will not add 9-16 horse, get a hiflow cat, like 40 bucks more from warpspeed or just gut yours if thats really what you want to do. epa though, they are watching you.

 

 

All right ... thanks guys

 

does that have a place? and the ones i have seen on ebay are primer gray etc...

 

1999 Cail-spec and 2001+ do not have an O2 sensor on/after the cat. No check engine light with a straight pipe on my car. The one above is not off ebay. Mine is made out of stainless steel with aluminzed flange.

 

I bouth the racing straight pipe of e-bay and was very happy with it. I totally eliminates the cat. And it is very inexpensive. Go for it. Nice sound also. Kinda a hollow sound.

 

So does it mean a test pipe like yours won't fit/work on Maximas with the 02 sensor?

 

The one I ordered off ebay had a spot for the o2 sensor.

 

I got mine custom made, but i'm pretty sure you can get it with an O2 bung on it.

 

I wouldnt get one of those, id just get a Car Sound cat from Warpspeed. Just my opinion, Take Care

 

a straight pipe increases the sound of the exhaust a lot i believe though?
