Weld in Flowmasters (Which Ones???)

[abouttobeglue]

2 chambers are for wussies, real men get one chambers if you want the best sound 2 chambers with a prochamber is it, it will drone like hell though, i had the originals so the super 40s or delta flows should be real close in sound with less drone. i switched out to magnaflows because it droned, then again after the magnaflows had a couple thousand miles and were broken in the droned at 75-80 bad. the pypes violators i have on my 06 dont drone at all on the freeway, im kinda dissapointed being able to think while your driving sucks.

I will have to put in another vote for the offroad MAC h pipe + welded in delta 40 combo. If you want original muscle car sound both at idle and wide open throttle this is the only way to go. I get a lot of compliments on the sound of my car.

I wouldn't do weld in. And I wouldn't go with Flowmaster. But if you must, get Super40. they do sound nice

 

[GTR_Stang03]

A set of Arrows on 2.5's ! They are a bit spendy, they are stainless and sound BBBAD A ss! Flow better than anything out there... Hands down!!

Get ur Done!

And the reason is?

Well. the reason why people do exhaust imo is to open up the somewhat of chocked out OEM exhaust. by going from 2.25 to 2.5 or free flowing muffler or what ever the case might be. so by welding muffler in, your just getting louder exhaust that not really doing anything performance wise.
And flowmaster with its baffle design, its no better flowing then stock muffler.

But super 40 do sound good imo

By the time you buy 2 super 40s, which is $70ea at Partshopper.com, and what ever the shipping may comes to.
plus cutting and welding muffler in-what ever the laber comes to.
where you can buy catback for around $380 with bigger pipe and cool looking tips.


By the way, i see in your sig that you have flowmaster catback. why do u need to weld in another flowmaster?

I would think a 2.5" Super 40 would flow much better than a OEM muffler. As I said earlier my car ran mid-11 with welded in Flowmasters....a 2 1/4" exhaust can handle plenty of horsepower it seems. The last time I checked $380 is quite a bit more than $150 BTW the Roush side exhaust is one of the very worse flowing systems out there

Oh absolutely.
Couldn't get Roush bodykit without side ehaust.
Didn't know about 333CSC at the time i bought it

Well the damn car looks great even if you don't have the most free flowing exhaust system out there I just don't think anything from the mufflers back makes much diference anyway

Well, when i went from Magnaflow catback to Magnaflow/Roush side exhaust, i noticed big difference in term of power. So i think it does make some difference. Ofcourse going from straight through to 180deg bend exhause tends to bug down power alot

You have no idea what you are even talking about the original 40 series is the loudest and deepest sounding muffler they make. Call flowmaster. Put an off road h pipe on too and look out!

WRONG!!!!!!!!!! I've had the Originals, Delta Flows and the Super's on my car with the same O/R X pipe and the Super's were by far the deepest. The originals are a bit louder and nastier I'd say

Got a standard 40 Series (not super or delta-flow) welded in on my sixer by a friend. Sounds great. idle sound is great at 1,100 RPM until the engine settles down to it's normal 800 RPM. Cruising speeds (40-50mph)at 1,500 RPM sounds good.

 

[Dragstr05]

I have the catback with super 40's and a bassani catted X. I really wanted an o/r prochamber, but I got my bassani x for $50 bucks from a friend, and it was a steal so I took it. Once im out of school though I'll probably just cut the cats out anyway.

Sound wise, its VERY deep sounding. Not raspy at all. Very tolerable inside, and alot louder outside compared to OEM. Not nearly as loud as an o/r setup though.

Power wise, the catback did nearly nothing at all. I *may* have gained a couple hp up top, but if I did it wasnt very noticeable. I noticed right off the get go a slight loss in torque. The X pipe however added a noticable power increase up top, pulled harder in higher rpm's that was noticed on my first run down a ramp pulling on to I-95, with no loss in low end torque.

ive got some kinda flows, were on the car when i got it, and a prochamber and it drones like a beast at 2100rpm... cruising 80mph SUCKS... im thinking its time for a gear just to keep me outta the "drone zone" but man does it sound good outsidE!

 

[the98stang]

Personally, I wouldn't go with Flowmaster, but if you want that "Flowmaster sound," go with the 40's.

Flowmaster's have too much drone for my taste. Bassani all the way!

I wouldn't waste my $ on weld in's. And the reason why I say that is simply because when I cut my factory cat-back to remove it, I couldn't believe it when I saw how restrictive it really is. The factory exhaust might be listed at 2.25", but that's O.D and in the straight lengths of the pipe. It's not mandrel bent so in the bends that go over the axle, at some points it's lucky to be 1 7/8.

Do yourself a favor and save you $ for a 2.50" cat back.

I love the sound of my American Thunder Cat-Back, but the BBK H is going to be gone in favor of a Mac Pro Chamber here shortly.

I loved the way that it sounds on Mossberg's GT wioth Flows.

BTW, No Drone here. Must be the gears

Is the stock system restrictive? Sure it is, but there is such a thing as overkill, and on a 99-04 GT thats stock or near stock, thats basically what a 2.5" catback is. Midpipes are 2.5", but the reason we get power from those is removing the cats. If I started over, I would have bought an o/r h or prochamber with MIL's and weld in flows.

When you have a ton of upgrades induction wise like TB and plenum, cams, intakes, forced induction/nitrous, then we start getting into where we would start to "need" a full catback vs the weld ins. If money is not an issue, just buy the catback outright. But if you would rather have 150-200 left over to buy something else, just get the mufflers welded in.

Overkill would be a 3" exhaust on a N/A car with very llittle done to it.

If you think that installing a 2.5" cat-back is overkill, I'll take some pictures of the stock pipes cut in half and show you how restrictive it is even on a stock motor.
