hey guys
i was thinking about getting the fast intentions 2.5 inch test pipes running with stock exhausts.
i need some feedback please..
how does the car sound?
a lot faster?...

comments appreciated

 

It will make it sound louder and gibve you a few HP. Selling my High Flow cats. Hoping to get them off the car tomorrow

 

i hear they also have resonated ones which reduce the rasp.. no personal experience though

 

so the down pipes dont do much?

 

If you are looking to increase sound with a little bit of performance and not spend too much, then Resonated test pipes are the way to go. They will help reduce rasp over the straight test pipes...

the resonated test pipes will supress more sound over the non-resonated test pipes. Although the computer will try to compensate for any changes such as intake or exhaust, and will recalabrate the motor to as close to stock as posible. you will have performance gains but not as much as you would hope for.

 

I got the straight FI TPs and I love the sound, esp with the FI catback matched to it

 

arent hfc better then the test pipes? why not just get the cats?

 

They both have advantages & disadvantages.

HFC Pro's - you're legal or "semi" legal in most states. Quieter. Won't have the typical test pipe smell.

Cons - more expensive, a tiny bit less power than test pipes

Test pipe Pros' - less expensive, more power

Cons - louder, 100% illegal in all states, test pipe smell (it's debateable weather this is really bad or not)

 

The resonated test pipes are 2.5" right? Thanks in advance.

 

That is correct they are 2.5" O.D...

Thanks, Tony

 

Can you describe the smell etc?

 

doesnt have a smell to me, guess if anything you can smell the gas a little more

 

i have question y would non resonated TPs give less noise.... i have stock g37 i took off my resonators on the car it has a much louder noise... so ur saying if i want to get TPs get resonated tps bc it had more sound to it???

 

Non resonated test pipes are by far your loudest option. This is also commonly known as: (straight test pipes)

Now what a good resonator does, is cut down rasp and interior noise resonance without sacrificing power and torque. In the process making the car slightly quieter inside and out...
