i am installing a injen ses exhaust, Any mods recommended so i can have a good sounding exjaust. I heard the H pipe is good, yes or no? How about HF cats? yes or no? By me putting H-pipe and HF cats, Will the sound get better and get more from the exhaust. My Z will be a daily driver, With alot of traffic, So dont want the noise if i can avoid it, I really like the look and would want to get a good sounding low tone, So please let me know if any recommendations.

 

Get the H-pipe. its worth every penny, It cuts the drone in half, plus makes it sound really good with hi-flow cats. There is ZERO drone crusing the freeway @ 60mph.

 

What brand of HF cats, Should i go, Does it matter or should i be looking for a certain brand?

 

i was at injen on friday and monday and ran dynos on the injen exhaust (we ran about 20 runs within the 2 days). hi-flow cats will make your exhaust VERY loud, but once you start cruising it should go away (drone). A cold air and plenum spacer also go very nice with this exhaust. definately get the h pipe. if you want some dyno numbers, let me know.

 

I'll take those dyno numbers.

 

So just install the H-pipe and that should be good? How about getting resonators?

 

ill get the exact specs and dyno sheets asap...
baseline stock ran 220.4 to the wheels
after all three were installed (spacer [skunk 2], cold air [injen], injen ses [newest version]) 240.7 to the wheels

 

Nice... definately interested in the dyno sheets.

 

ill get it up as soon as i can get a scanner...this test will be in an editorial coming out in import tuner, maybe in the february issue.

 

Just got it installed it sounds awesome, Very deep sound, In my opinion its very low and deep, Sounds like stock just deeper, and i feel the extra push, Very happy with the results.

 

you didn't notice any power loss at the low/mid range?

 

Not at all, I felt the gain and the car has, Some good power gain. When i hit the pedal the push comes when requested.

 

where did you get the install done at? did they do a good job? how much?

 

it was Called Atlantic Muffler, In Los Angeles. Very good job, They do alot of custom work, They are very experinced and do custom work also. They charged me $75 to install, Take it the injen exhaust was of a G coupe, So they had to custom cut and install, So alot of mods where needed to make it fit.

 

wow did you have a hook up or was that just a normal price?

 

normal price.
