How much hp and torque do you approximately gain from this exhaust?

 

NONE, a nice noise...

kthxbye

 

I agree, you don't buy it for the gain. However the sound.....

 

o ok thanks

 

Yes.

to the op, putting on the coupe midpipe and HKS exhaust probably released 3-5 horsepower total at the crank. This is probably a 2 horsepower increase at the wheels by better exhaust flow, less back-pressure and weight savings. It is just my guess--no dyno other than butt-dyno. It feels peppier, engine revs smoother, and tires chirp a bit more.

But as my ava-text says, it is mainly an orgasmic sound mod.

 

Mufflers are *usually* for sound only on an N/A application...but i love when the civic guys claim a 30HP gain from a muffler.

 

^lol
In civic ville, you add the numbers claimed by the manufacturer...regardless of the application

 

If you want power from your exhaust you have to replace parts forward of the cat. (y-pipe, hfc, headers)

 

Uhh, the y-pipe is downstream of the cats...

 

I stand corrected, but my point is still valid. Look other places for power gains in an exhaust other than the muffler.

Im just an internet mechanic, parts go where I envision them while sitting at my computer chair. haha

 

Good luck installing some HFC like that lol

 

No, no, no... you guys keep getting it wrong... it's the stickers that come with the exhaust that makes the power...

 

sighh... I always thought it was the extra 3 wings they put on.. or their real "aerodynamic" body kits.. along w/ their super cool glowing lights..umm HKS is for sound btw.. real nice sound..

 

I think the HKS is **** and a Megan is a good inexpensive alternative that sounds good and shows some gains.

 

The problem with Megan is it is too loud for some people. I don't know if anyone has dyno'd it to see if it has any gains, but it is possible the Megan doesn't increase hp either.
