Im just curious to see what everyone thinks. I prefer the cattman 3 inch. It looks better, sounds better and does the job well (when my car is not in the shop ).lol . So i just want to see what everyone has to say about either of the exhaust set ups. Feel free to chime in























P.S im bored....thats y i decided to make this thread

 

Cut-out = more HP (I believe).

 

Going with both would be nice if your car was on nitrous...

As far as N/A is concerned a 3" is the best all around on the street and track.

 

I think you'd gain more power with a cut-out

But cattman exhaust would sound 10x better.. But with the cutout, you can just keep it closed when it's not needed

 

Got the 3in Cattman love the thing with the other mods cant wait to get those headers and as far as the cut out goes dont know what the F22k it is, does anybody got pics of it!!But loving the Cattman till the wheel fall off!!

 

in for best cutout link

 

sorry to ask, whats exhaust cut out?

 

prove it......it might work better for boosted cars...but for a regular slighty modded maxima its pointless. Especially for those who have it and still running high 13 sec passes or slower. They make all that noise and barley trap over 100mph. What is the point?

 

I recall seeing dyno runs of the two and the cut-out yielded more horsepower. And besides, 1/4 miles aren't really a measure of horsepower anyways.

 

The trap speeds are an indication of power, though.

 

if u find the link please post it....your right 1/4 mile runs dont measure horsepower. But when your car is the loudest thing there and u only running 14s it makes ya look dumb. Why make all that noise if you aint makin no power?

 

not a 3 inch, but 2.5,,car def felt stronger on top end but lost some gitty-up down low
with cutout


without

 

Cut-out is waaaaaaaaaaay cheaper. Plus, you have a quiet car when it is closed. I think the cutout is better for those who care more about having the power at the dragstrip, and the 3 inch is good for those that want the power/increased sound all of the time.

 

That's a good way to put it

 

In a FI situation the cut out would be most beneficial and make the most increase in power ....especially the turboboys!

 

Since the cutout steals some power down low, I would get an electrical one and open it once I get going.. Still have low end power and the cutout yeilds some high end power

 

It doesn't work like dat...to get the most power out of a cut-out u have to tune it with the cut-out open the entire time.

 

.............

 

Exactly...That's what I did to give me the best results possible on the track.

 

Here's a vid.

 

this thread startd i believe cuz me and datdude got into a lil argument about the 3inch and the cutout.... me i wuld deff get a cutout for lik 80 bux over all that 3inch crap lik test pipe and catback (costin you lik 700 beans( but we aint all ballin like datdude lol)and yeild around the same gains...ok i might loose low end but who cares...loose low end and reail ur challange in with top end...i have a 2.5 megan catback and love the sound...when im redy for more power just flip a switch and off you are on the highway...when ur done shut it lol

 

Well, which setup somebody prefer vs which works better is completely different... if u prefer a cut out then in yourr case a cut out is better than spending... I don't mind running a cutout, I'm more of an exhaust junkie and datdude can vouch for that lol... rrod you said you saw dyno difference???... where iirc the dyno was between a 2.5" catback and a cutout and the cutout made very minimal gains and minimal tq loss iirc, I wanna say there was something like that here a while back... overall I say the catback due to sound, looks and OVERALL performance, while a cut out MAY give 1 or 2whp over the 3" you will also loose some TQ which is something quite often overlooked

 

the catback makes hp across the board. With the cut out u loose hp before u make it .

it seems to me the only reason u dont like the exhaust is cuz of the price....smh














P.S. im not a baller

 

Manny you are bored lmao! Wasn't the game time enough? lmao!

 

i dont even think it will give u a peak hp gain over the 3 inch tho

 

Doubt it... again sparks would be the guy, he has em both on now

 

i guess 3 inch vs cutout would yeild similar power but i'm going for cutout with 2.5 catback which will be good enough for me for the price (price plays a huge role for most of us i think) but i will admit i would love to own a 3inch cattman

 

donno why he doesn't post as much anymore.. learned a lot from him

 

I think it was 2.5". You are correct.

 

QFT.

 

I'm trying to weigh this option as a serious one, but I wanna just get this straight.

So cut-out, since you lose the backpressure of a full exhaust, you lose low-end hp AND tq then make comparable gains to a 3" setup?

Also, when you mention being tuned while using the cut-out, do you utilize a piggyback with two diff maps or something? I imagine when you close the cut-out the car would run like sh*t if still on a stock catback or something.

 

His fastest times are with the 3in cattback I belive

 

If you could buy a (decent one from QTP) cut-out your gonna spend about 175 and 75 for instalation. Then add on the price for a good quality cat back (mandrel bent) atleast 300-550 for a 2.5..if you do the math it totals between 540 and 710....I know around here its a place that makes mandrel bent. 3 inch catbacks for 600 and of course cattmans are 7ish....so if you think about it u can get afford 3inch

 

I was at before the game man...lol

 

Backpressure?

 

My car was tuned using vafc2 with the cut out open at wot. My car runs just fine on the street with the cut out closed. But, like I said before, I hardly push my car on the street...Heck, my wife actually drives the car on the street more than I do. I only run the car hard at the track.

 

What you stated is true, but I went a much different and cheaper route. I have this cutout: http://www.summitracing.com/parts/SUM-670136/ I also still have my stock cat back, because I love the slightly increased sound the headers and no cat provides. I would imagine a catback on my set up would be quite raspy. So, in total I spent about $60 for my cut out set up. ($27 for the cut out and $30 for an exhaust shop to weld on some flanges for me.) I did the install. $60 compared to $700 is a no brainer for me. But to each his own.

 

What is the reason one would lose low-end from a cut-out as opposed to a full exhaust?

 

For those worried about lowend loss hook your cutout up to an RPM and WOT switch. Problem Solved.

Im a cutout supporter!

 

Yup I have the same cutout and planning on doing the same thing this weekend.
