This is my Question

[sakigt]

Dual exhaust doesnt not mean dual pressure from both sides. We are not in v8s....Did you see the SRT video where it showed that? Even the car buildup by Sport Compact ditched the duals.

Lets use basic logic here. Why would a company say product A is necessary for product B, when product A has an INFINITE amount of competitors???

TO SELL MORE!

Its a giant ripoff, IMO.

Need a better example?? Since you guys worship 3Bar...

On his sig...does it say: Stage I and Mopar exhaust?? No. Its doesnt. Lets think about why that is....

Everone I know with a turbo'd 4 banger (except you guys) agrees a 3 inch exhaust is much better (and worth it) than anyhting else, so I am dumbfounded as to why youre arguing about and even smaller pipe? We have numerour vendors come here trying to offer such a system and they keep getting brushed off. I dont know anymore...

[ptgtcb]

I believe 3Bar mentioned he was running a 2 1/4 race pipe.

Who are all these vendors? Exhaust depot asked what we would like and never heard from him again and I don't remember any negative responses. Now we have Scottmech, who may actually offer us a quality piece. So I count 2-1=1.

I contacted every down pipe producer and not one would make a down pipe for the GT which would consist of extending the SRT 2 1/4" portion about 6" man that would be a manufacturing nightmare, real tough.
Which brings up another problem why do they neck their down pipes to 2 1/4 when everybody seems to want 2.5 or 3"?

The problem for the PT with the SRT down pipes is that they are all too short and the problem with the 2.5" exhausts is that they all adapt to the 2 1/4 stock CAT so we are left with a gap of more than 6"(more like 10") if you adapt 2.5" exhaust to the SRT down pipe(s) cutting off the 2 1/4" section.
Scottmech is now going to produce a down pipe for the PT great, hopefully you will be abe to install it directly to the stock exhaust or directly to a 2.5" exhaust.

The biggest flow problem with our cruisers is the CAT so that is my first priority and then MoPar tells us we need a 2.5" for stage II but when I examine the MoPar 2.5" CAT back it is NOT a true 2.5" exhaust system so I ask myself........ My original question which is the topic of this thread.
So this is what I am going to do, Install a 3" down pipe to the stock exhaust reinstall my btg axle back and let her rip. Besides with the smaller pipe you keep the heat in the exhaust(hot molecules move faster)aiding in getting the exhaust out faster anyway.
Did anything I just wrote make sense or matter, I doubt it! [:0]

Heh, they sure don't worship me. Give me heartburn maybe.

The funny thing about your question is... No, can't let on yet.

I'm such a tease. [}]

Are you running a 2.25 race pipe?

3BarBoost,

Can you at least tell us this...

I have the Borla 2.5 catback on order (single outlet, twin tail-pipe).
It's on backorder and I understand the Mopar catback is on backorder also.

Should we be cancelling our order and wait for some new release that will be better? I sure don't want to spend $400 plus now, just to find a Mopar upgraded version coming out this summer...

It is my understanding - I think from 3Bar - that the CAT on our GT's are free flow. If not ptgtcb, there are many free-flow CAT's on the market.

No, no catalyst is free-flowing if it is doing its job. About 80% of total system backpressure is from the production catalyst. That's why your cat-back exhaust systems only make minor differences in power (10-15 bhp). The Mopar cat-back and most other 2.5" systems are more than sufficient to fully realize the power stated in the upgrade kits. We haven't found any delta from a well-made 2.5" to a 3", so we are selling a 2.5" system. It's lighter, so you'll be faster - right?

Race pipes are almost guaranteed to get you in trouble if you use them on the street because how loud they are - unless you are sneaky. I leave the stock muffler on even when I install the race pipe for trips down the strip and other sorts of power-rewarding activities. So there you have it, my solution to mid-14s.

I've said similar things here ->

I had a 2 1/4 in "race pipe" sans cat that went out the drivers side and it sounded awesome I only got pulled over once and the cop said it was cool and sounded good. it is real quiet at idle but when you get it up to 5000+ and let off it sounds like a 21 gun solute. AWESOME!! I recomend it to everyone

That is why I like the ATP down pipe. You can swap out the CAT with their test pipe in 5 minutes. A larger CAT is sill restrictive ,but, it is going to flow better than the stock CAT.
Thanks 3Bar, you don't realize how much I worship you

mich_132003, yes there are a lot of downpipe w/ highflow cats assemblies out there, I think I called everyone and no one seems to gives a rats a$$ about the PT. None,so far, will just bolt up. scottmech is making one though, but I won't be able to swap out the cat easily. Unfortunately, my problem is I want the best of both worlds. I am just going to have to fab the missing link from the ATP to the 2.25 or 2.5 cat back.

Just to let you know there is a company out there that is coming out with some bolt on performance that will give us 350 streetable HP and up to 500 not so streetable HP and reliable. We all may want to wait about 90 days.

Flowmaster now has a duel sys for the gt, (I heard and saw it on a car, but don;t know anything about it) I do know the size goes with the hp. if you have 300 hp you need 3" exhaust . if you have 250 hp you need 2.5" exhaust if you have 215 hp the 2.25 or the 2.5 exhaust would work just fine . Unless you are tring to set a record on the track then any exhaust Your preferance of manf will do. For me I am still stock, single exhaust factory installed, would better sound but for 600.00 I will just turn up the radio.
