Well said by someone who has never driven a 2.0L with a 2.5" exhaust. You guys speak with no real experience...
Waterpumper's 2.0L cabrio is one of the strongest normally aspirated ABA street legal motors here on Vortex and has dyno's to prove it.
I have driven it myself and compared it to mine. My car with 2.25" exhaust is only marginally faster off the line than Brandon's but his kills me up top. This is also due to the fact his Kent 260 has a 11.17mm lift and my Schrick 260 only a 11.0mm lift. So that in conjunction with his larger exhaust flows way more freely.
So unless you have experience with the mods people are asking about, don't post misleading info...

i have a 272 camshaft...adjustable cam gear.. chip blah blah blah all that good stuff ....so you drove both ...and seen much more pick up through the whole powerband with the 2.5? as apose to your 2.25? ......does vwtech run a cat?what does his whole exhaust system run?

Re: hyperformance cats and exhaust sizing for the 2.0.... (DomozitoLK)

blow it out your ass,
i work for a exhaust company and DO have experince with it. We've dyno tested several 2L's with 2.5" and lost power with those.
Secondly he never said, I have cam's/ and headwork what exhaust is for me.
He merely said 2L and 2.5"
So you sir can go Fak yourself.
And to top it off, i did have a 2L w/ 2.5" exhaust, 85 gti w/ a built 3A block and headwork, and i still preferred my 2.25" system to it.
In addition to that EVERY exhaust company's stuff flows differently, we Magnaflow flow really well and 2.5" was to much for a NA 2L

Let's see some proof then...where's your dyno sheets? Because I have some for you Mister Exhaust Company employee. This doesn't look like a horsepower loss to me. But what do I know about exhausts...

So why didn't you ask for more information before answering. I've seen Stealthdemondub's posts before and know some of the mods he's done.
Pretty mature...
A 3A motor is not an ABA motor. They don't tune the same. Why do you think most of the Mk1 & Mk2 guys swap the ABA into their cars?
Fine, you prefer 2.25" exhausts...my whole issue is with you spouting falsehoods without proof.
If you do work for MagnaFlow...I have lost all respect for your company based on your unprofessional response to my post.

Re: hyperformance cats and exhaust sizing for the 2.0.... (Lord of the Blings)

ok. . . I am talking from what I know. My freind had a 95 Jetta 2.0 with 2.5 exhaust. He seemed to have really good top end because he could chirp the tires into 2 maybe 3 and that was with just his cheap made exhaust (2.5 piping and some universal muffler), and an abd intake that's it. Me with my 97 and my 2.25 exhaust I really can't do it, or at least haven't heard it. I have 16's and different tires. His were harder rubber so that could have helped him with the chirp.
So basically from what I know and what you have on your motor I would say go with the 2.5. This is because you have a fairly large cam so you will be flowing more air than a stock 2.0. Also since you have the gear if you don't have enough low end for your liking you can adjust and pick up a little more.
I think if you were to get 2.25 you would not be getting all the top end you could get out of it, which is what I think you are going for with that cam and your other mods.
I would also say get a high flow cat. Don't knock it out. For two reasons you will have trouble passing inspection. And you will definatly loose some low end.
So I would say get a good high flow cat with the 2.5 and you should get a good feel out of it. Then just mess with the gear to fine tune the power you want. Either way good luck with your decision. By the way I love the Jetta

stealth- before i became a member of the FI family- i was running TT racing downpipe to Random Technologies cat ( 2.25") - put it my 266 cam and gear and THEN the exhaust and the diff was night and day- things flowed very well and the price was nice also ( TT dp- $175, Random cat $175) sorry-cant chime in on the 2.50"- but in the spring i can tell you what 3" is like(w/the t3/4of coarse)

Stealth, 2.25
smaller diameter pipe will help you keep what you have on the bottom when you cam the hell out of it....

and smaller pipe sounds so sweet. just ask anyone who has heard my car
it friggin rips!

Re: hyperformance cats and exhaust sizing for the 2.0.... (STEALTHDEMONDUB)

Sounds good to me! http://****************.com/smile/emthup.gif But on serious note, the theory of a stock VR6 running 2.25" piping makes sense to me. If your NA 2.0 produces what a stock VR6 produces, then 2.25" is all you need. I don't know anything about canyon driving, so you gotta ask yourself if top end power or low end power is beneficial for your driving application.
