ok so i have been in the market for a catback exhaust system for my ef for some time. basicly ever since i sold my rsr gt2. i sold it due to the diameter of the piping, 2.36in just wouldnt cut it anymore due to the fact that im going turbo.

i have looked at many exhaust for the ef's but many of them arent 3'' and 2.36-2.5 is just too small.

i basicly have narrowed my choices down to one exhaust the 3'' catback thermal r&d. it is near impossible to find a used exhaust for the ef's you can find crx catbacks, but they come up a tad too short. and then you run back into that issue of small piping diameter.

my question is the thermal 33'' r&d the only 3'' catback for the ef's? i have been looking and unless i am looking in the wrong spot i havent seen another company with the 3'' for ef. ive looked at rsr,greddy, all those brands and im not looking to go with a cheap exhaust basicly looking to get sumthing with good quality along with long life and great sound... definitly mainly looking for a performance geared motor. i know the thermals are non resonated but with turbo it isnt as loud as normal non resonated exhaust

who else has one out there for the ef? and how do you like it? anyone know another good quality brand putting out 3'' catback or are the thermals and custom the only way to go

 

do u really want a catback? why not build a system of ur own?
u can still use a crx exhaust...just have a muffler shop weld on an extension

 

You can buy a Kteller kit which comes in SS or aluminized and pick the muffler you want and install or take to a muffler shop to have them install.

 

how much do the ktellers go for?

http://www.kteller.com/store/a...ce62b

$200 for mild and and $225 for SS

 

how do those sound up against other exhaust like the thermal r&d

i know alot of how the sound is produced will depend on the muffler you choose and thats the main thing i dont want a shitty sounding exhaust and mufflers can get pretty expendisve.

basicly what i was thinking of doing is getting the r&d off here for 590 shipped and then get a custom cat delete made for 100.00 by a local fabricator.

 

seems like you got ur mind set on the thermal...go for it, if you really want it...but why not go custom? its gonna run you less and probably will sound better...IMO the thermal is too loud...
but if u do go with the kteller piping...shell out the extra 25 bux and get the ss....trust me its worth it

 

do they have sound clips or sumthing?

its not that im ''set'' on thermal its just i have a friend who has a turbo ef with the thermal and it pretty much sounds amazing loud maybe but a raw exhaust is going to be loud and not restricting the exhaust will always be loud pretty much

 

I hear the resonator is what also gives you the low deep sound. The bigger (longer) the resonator the deeper the sound will be. My Invidia cat back sounds great and it's got a big resonator.

Good luck
JG

 

thing is resonators could rob power from the turbo application, prolly not much but many of the turbo exhaust you see are non resonated

depending on your boost level 2.5" may be just fine, 3" could be overkill and actually hurt your performance.

Then why would people run open header and have exhaust cut-offs and such?

open header, like just a stock header with nothing else? thats RETARDED, that gives you the MOST TURBULENT flow possible and it will rob you of low end. if you have too large of a pipe, you will lose flow velocity, if you lose flow velocity it is just as bad. god when will the backpressure bullshit end?

I think he means turbo cars running high amounts of boost...
Why do they run open header and have exhaust cut-offs...

define high, give examples of turbo size, etc. all this **** is way too setup specific. for example, lets say n00b 1 is running a greddy kit and n00b 2 is running a t67 turbo on his car. n00b 1 will NOT require the same pipe size as n00b 2 because n00b 2 is obviously flowing more air into the engine, thus, n00b 2 needs to flow more air OUT of the engine, n00b 1 does not need as large a pipe size because n00b 1 is running a far smaller turbo with lower boost (comparitavely)

 

Honestly, who needs 3" unless you need to move some serious air. If it's too big it hurts your performance, and sounds like ****. But to each their own.

Why do people always argue about this? It has been proven time and time again that 3" exhausts make more power than 2.5" on turbod cars...no matter what the boost level or turbo size. Jeff from EvansTuning went over this a long time ago...as well as many others. Besides...you dont know his setup so you are basing your opinions on an unknown fact. What if hes gonna be using a 3"dp? Would you put a 2.5" exhaust on a 3" dp? If so then youd be retarded.

And, once again, people have made more HP on open header(or with a dump) on built NA cars than with a full catback. And of course you lose midrange...but not all types of racing need midrange power. If its an all out drag car then you wont be in the "midrange" the whole time youre racing. Randy Monroe(RMF) has proven time and time again that open header does make more power on a highly modified NA motor. If its not hihly modified then you prolly wont see that much(or any at all) of a HP gain.

Everytime i see you and your budy CRXbart yall are posting something negative. Why not post something positive that could actually help. We really need to clean up this forum...there are too many negative people in here these days

BULLSHIT, i posted mother ******* FACT. its simple physics, if you flow more air, then the air needs to exit at a higher VELOCITY, that higher VELOCITY requires a LARGER PIPE, lower velocity + large pipe = slower exit speed = LOSS OF POWER. and if you have EVER ran your STOCK header open you will know that the loss of power is EVERYWHERE and it slows down your revs due to excessive exhaust turbulence. however if you are running an OPEN RACE HEADER that is a completely different scenario, you ******* brainless douchebag asshat.

Going to sound different on an N/A , it will be louder

 

If you're going to do a FI setup or built NA on you're car then the 3inch thermal will do you good. If not stick under the 3 inch... like the tanabe hyper medallion, rsr, thermal, etc.

HAHAHAHA...calm down kid. No reason to get your panties in a bundle. Youre higher velocity arguement has very little to do with turbo cars. Heres a general rule of thumb for you(passed on to me from VERY reputible race shops and many threads on HT)...NA cars need more velocity than voume for power....turbo cars need more volume than velocity.

You arent taking every factor into consideration when youre forming your uneducated responses. Have you ever heard of thermal expansion? The exhaust leaving a turbo will be ALOT hotter than a header...this means that the exhaust from the turbo will need more room to expand(thermal expanion). If it cant expand as it needs then it WILL cause alot of turbulence right at the exit from the turbo. This turbulence=less HP.

Youre also forgetting that turbo cars dont depend on exhaust pulses to pull the exhaust from the engine like NA cars(hence the need for higher velocity). The air is being forced out of the turbo. When in boost there is positive pressure on BOTH sides of the engine(intake and exhaust)...which means that the exhaust coming from the turbo is being pushed out...not pulled by scavenging effects. Why dont you go pick up a few fluid dynamics books and read up before you come back with another uneducated response.

Yea, idiots usually resort to name calling and other childish behaviors when they know they are outclassed. This doesnt hurt my feelings...i makes me feel sorry for you.

how about posting links to your sources? oh, you dont have any. i could supply you with any physics book to prove all of my points. its simple, an engine is an air pump, the more air comes in, the more air exiting. you are pointless to talk to because you cannot grasp these simple concepts. this concludes your broadcast day.....click.

Dude are you serious? Here you are quoting old school quotes thatare based loosely on facts. Im posting facts that come from years of studying fluid dynamics and other forms of physics. I did post my sources for proof. Jeff Evans at EvansTuning.com and Randy Monroe from RM. You can search for them on here and read for yourself. EvansRacing even has a web forum. Go in there and post your uneducated nonsense and see how they respond to you. They will treat you like a little kid...which is the way youre acting right now. Im posting this from years and years of studying and research. Look at the bottom line of my signature...do you think i could port heads succesfully without knowledge of airflow? Please dont act like you know more about me in this subject...because i dont have the time to make these long posts just to prove you wrong. Youre some kid that is saying stuff that he has heard. Im an adult posting on subjects that i know about.

Thats the thing. I grasped that a LONG time ago. And ive also grasped that the statement is based VERY loosely on facts. Youre problem is that youre only grasping the simple concepts...and not digging deeper to actually find out why things work the way that they do. You might have over 3k posts...but that doesnt mean that you know anything. In fact...the past 5 posts that ive read coming from you have showed me that youre an uneducated brat that thinks he knows alot...but in reality knows very little. Swallow youre pride man...youll get much further in life
