How much hp can i get from each one. And is it worth it?

 

y pipe if about 15 horsepower.i wouldnt get the mevi unless you get the ecu upgrade otherwise its not really worth it. you lose most of your low and midrange power. i have a 99 and i noticed a big difference in the power loss.. but high rpms are much bette.i can feel the car pull alot more after 5000k

 

really 15hp...so i will be able to tell a big gain? And how is the sound i dont want the ricy sound...like a civic.

 

yeah you can tell there is more power.depends on if you have stock setup i dont think it sound any different. i have b pipe and after market muffler so mine as a deep tone to it

 

the mevi makes the car sound more refined in the high end...when it kicks in...and less menacing...but I like the sound changeover personally...the loss of low end and mid range is definitely noticeable unlike people say even with the ecu...but why are you in such a hurry around town anyway...(ie. most of your time spent in the low end there)....the only time you really need a lot of power is when racing which takes place in all the upper rpms...where the mevi pulls like no other!!!

 

Witht he ECU the loss is recovered but the gain you'd get with the stock IM isn't there either so you're pretty much at square one in the low-mid power range.

 

if you replace your y-pipe, sound will not change that much. sound like stock. get an intake with the y-pipe to get the most out of it. if you decide to replace your b-pipe make sure it has a resonator otherwize "a fartcan is born"

 

Y-pipe is 18 at the wheels. You can feel it.

 

unresonated B-pipe only fartcan with OEM muffler. With stock muffler just has a kind of loud undercarriage note

 

yeah I would go for both but like everyone else says you gotta get the ECU....the y pipe you will love

 

Your sig states 321 HP boosted, and you DONT already have a y-pipe? ! The JWT ECU wont work unless they tweak it for boost, as you say you have, otherwise you can kiss your engine buh-bye

 

Yah what's with this question? I looked at your cardomain and it says you already have a y-pipe and mevi on your car. Just trying to get your post count up maybe?

 

why dont you just get the cattman headers and y pipe instead of just the y pipe its much better. im going to be getting one here soon.

 

if you're boosted a MEVI will give nice gains

 

The headers are a good idea for deeper sound and some added Hp but it costs so much...upwards of $900.

 

How did this thread get resurrected after more than 9 months?

 

good question, I just read through it and noticed the dates ...
