Hey tom, I know you have stated that there are good gains to be made from a 3" exhaust on an n/a svt- my question is, does this take away from the bottom end power or is it across the entire rpm range? also do you have a before and after dyno of switching to a 3" that you or anyone else who has this could post, if not what kinda numbers are we talking about with this setup- also do you have a program/tune for the predator for a 3" exhaust. Thanks any info will be greatly appreciated- by any and all who contributes- thanks again

cool- post it when you get a chance i'd really appreciate it- thanks, also is that across the entire rpm range or at the top end or do you lose low end power at all?

I am in the same boat as Tom on this one, a 3" exhaust does an engine good even on NA. I have it and besides the obvious power gains the 3" just sounds better [:)]

Yes you will see gains but only after like 4500 rpm. Youll get horrible gas milage if you drive lowend though

I wouldn't say that. I still get 28mpg on the highway with my 3" and everything that is done to my car. I even stay above 20 when i've been messing around and doing alot of city driving I think thats pretty good

I got 37 mpg before I started to go goofy with it adding more mods.

Theres no way you can back up a statement like that.......

I ran 3" on mine for Months prior to getting the turbo installed, it had more power... even down low and it did not effect the milage.

Not at all , low end wasent hurt at all from what i remember , I start my Dyno runs from 2000 on and from what i remember there was no loss and im thinking a gain from 2000 on with going to 3 inch

Im leaving for Co. early in the morning to tune a Focus and will try to find this dyno when i return

does a 3 inch just sound like crap on a n/a focus???? I am getting a turbo set up and a 3 inch will be a must but i was thinking about just putting it on now. does anyone have any sound clips of a 3 inch on a na svt or even a reg focus?

Thanks

trubendz makes a 3" exhaust with your choice of mufflers from magnaflow borla and i think a couple others

hey guys- when i do go to a 3" should i do the flex as well or it wont make a difference w/ a 3" flex- i mean my hfc will only 2.5 so would it even matter to do a 3" flex?

i didn't realize the flexpipe is different between the regular Zetec and the SVT's. Sorry! Is the stock SVT flexpipe 2.5" ?

SVT flexpipes are different. The attached pic shows the SVT exhaust in the back (with an offroad pipe), and regular Zetec exhaust in the front.

my 3in exhasut doesn't sound all that great with out my turbo applicaiton. i just had a local exhaust shop weld the 3in pipe onto my exisitng flex pipe worked quite well

FocusSport 4-2-1 header with Focus Central 2.25" flex into a 3" exhaust


Why on earth would you want to go to that header over a SVT header i thought the reason we did all this was to gain power ? why change to a header that will loose power

Going from a 2.25 exh to a 2.5 is a waste of time and money

Yes you can buy a 3 inch flex

Well actually that was my old header but my new header won't make you much more impressed, the JBA. I looked at the SVT but am going to try this JBA first. We plan on dynoing the SVT header to see what it will do in comparison.

I don't know Tom, I never had a bad experience with the old 4-2-1 and made very good power NA. We will see what the dyno says when we try different headers out.

LOL I think the key here is that Goat Roper has a ZTS, not an SVT.

Where can we get a 3" SVT flex?

cayres

you can buy a 3 inch universal flex and have brackets welded on...just google search it and youll find a lot of companies that sells them

Tom was saying that you can buy a svt header for around the same $ as you would spend on the FS header. So why not buy the svt one...I think??

try the 3 inch throw it on the dyno and see what happpens...

isn't there any reputable company's that make a 3" flex for the svt?

i had a FS header and a 3 in exhaust. it was SO LOUD. but once i put my turbo on it sounded alot better. but NA it sounded like crap.

Give him some time...Cause i do remember he said that he was going out of state for a few days to dyno tune someone's car. So I doubt he's at home right now and most likely won't be able to post it up till later this week.

OR... Since he's going -a-tuning, he most likely has his laptop, and answered remotely.
