I know a HR y-pipe will make a slightly increase in sound for the OEM exhaust.

How will a Stillen Y-Pipe sound with the OE exhaust? Louder then HR? Rasp? i tried looking for a sound clip havent heard one yet for OEM exhaust.

As for TP i was looking at Fast Intentions. How are Non-resonated TP holding up??

I was thinking my set up FI Non-resonated TP + Stillen Y-Pipe to increase my OEM sound.

 

I herd one with the HR y pipe and he had test pipes as well. Had a little rasp to it.

 

Or you can take the resegnators off (sorry about the spelling have no clue how to spell it) and it will give you a louder stock sound as well I have that done to my G right now sounds good.

 

In the real world changing the y-pipe will have zero effect on sound or HP increase. Check out MotorDynes test pipes or BERK'S HFCs either one of those will improve the sound of your OE exhaust and give you some added HP. Just depends if you want to keep it "Legal" or not....your choice!

^ Art Pipes ftw, or hfcs if you want to keep it legal.

 

Y-pipe has no change in sound?
i heard the HY y-pipe it has a very slight change in sound on youtube.
are you sure???

then i might change my mind in getting a stillen y-pipe and just get a resonated tp

 

A bit of an increase in dbs, but doesn't justify the price, imo..

 

My friend put a ypipe on his maxima and it sounded much throatier than his oem

 

HR Y-Pipe does change the sound of the oem exhaust. It has also been dyno proven to give 5hp.
