straight pipe

[CoupeVQ35CVT]

I just used a air gun and the bolts came off real easy... and as for loss of low end power, ironically I actually got better 60 ft times at the track....

Well that right there should dispel any myths about back pressure helping low end torque. So with a straight pipe you either had better overall performance (including low end, as logic would suggest) and/or your tires just hooked up well that time.

not to dis mehdi or anything but he didnt know what he was talking about... ive track tested my car and have numbers to show that it is actually faster... i ran a 14.4 stock, 14.2 with exhaust, and a 13.9 with no muffler and all were at the same track with similar weather conditions. mehdi did say its not the best thing for daily driving and i agree with that because you'll have no back pressure and you'll lose a lot of low end power but up high it will pull much harder and scream like crazy..... thats why i got a electronic exhaust cut-out. so i can chill and drive normal and then hit the switch and have my car like its straight piped.

thing is, both 2.5s and 3.5se have MORE then enough power for daily driving if its stock or straight piped. only difference is that straight piped is faster for racing.

A word of caution while using your exhaust cut-out.

Actually three words: Carbon Monoxide Poisoning.

Since the exhaust is not exiting at the rear of the car, exhaust fumes may enter the interior, and poison you and your passengers.

Automotive engines emit several types of pollutants, including carbon monoxide.

What is carbon monoxide? Carbon monoxide (CO) is a colorless, odorless, poisonous gas. It is a product of incomplete burning of hydrocarbon-based fuels, and is a by product of the internal combustion engine.

Why is Carbon Monoxide Dangerous?

When carbon monoxide is inhaled, it passes from the lungs into the hemoglobin molecules of red blood cells. This causes interference with the oxygen transport and gas exchange abilities of the red blood cells.The result is that the body becomes oxygen-starved, which can result in tissue damage and death. Low levels of carbon monoxide poisoning cause symptoms similar to those of the flu or a cold, including shortness of breath on mild exertion, mild headaches, and nausea. Higher levels of poisoning lead to dizziness, mental confusion, severe headaches, nausea, and fainting on mild exertion. Ultimately, carbon monoxide poisoning can result in unconsciousness, permanent brain damage, and death.

To be safe, keep your windows open while driving with your exhaust cut-out open.

To really be safe, consider installing one of these in the interior of your car:

Be safe out there!

The effect would be an annoying bumblebee going down the street pissing off all the neighobrs...way bad idea on a I-4 ALWAYS

I4 HATING FTL!!!!!!

Can someone do a write-up on how to do this and ESP or someone that has this done can you make a video so I and the people considering this can see what it sounds like. TY

i did a before an after clip..this exhaust is so low its hard to hear on the video camera..10000 times better in real life..but here it is anyway..

before:

after:

and heres another after clip in a different angle just because i was bored lol:

that sounds amazing!

and about the cut-out and the carbon monoxide, i only use the cut-out if i'm racing or driving fast and at that point the exhaust has a good amount of pressure and its all blown out the back of the car. i dont sit in traffic with my cut-out open and windows down... i'd sit in traffic or low speeds with the cut out closed, windows up, and the A/C on max lol

The before and after video is not working but the one below that is, it sounds crazy WOW .

But don't you have exhaust and 3.5 , im looking for a stock clip 2.5

[6SpdAltima_Coupe]

o i guess i misunderstood you then sorry lol

[AltiCoupeDriver]

Nice. How much did it cost for welding? Does it drone and could we get a fly by vid? Sounds real mean.

[6SpdAltima_Coupe]

thanks and it was $200 in total..as for drone its not too bad at all..its not a real consistent roar, just when you accelerate..but i hav a 6mt so idk if it would be different from a cvt transmission..and yea ill try to get a fly by video today
