Best Flowing Mail order Exhaust

I need an exhaust that runs in the stock location over the axle and exits at the rear either to one side or duals, the important thing is for it to flow well, and I'd like it to be loud also. It will be welded to the 3 inch pipe I have coming off the hooker 2055's in place of the cat. Right now I have a 2.5 inch I-pipe and it seems restrictive. I Need it to come in the mail preferably from Jegs or summit and price is not really an issue. Part numbers would help. Heres some I'm considering
-Flowmaster 17233
-SLP loudmouth
-Magnaflow LS1 15684
-Borla
-Edelbrock 5672
-Hooker 16823

Flowmasters are proven to be the worst flowing exhaust compaired to other after market brands. You cannot go wrong with Hooker, Magnaflow or Borla. That would be the list I would choose from. The loudmouth may be what you are looking for. It is obnoxious when you have any motor in front of it. Especially without any cat to muffle it. It will take a bit of fab work to use a 4th gen system but plenty of members have done it. Beware though, as I have heard a Hooker long tube/no cats and loudmouth equiped LS1 and it sounded HORRIBLE. It was louder than a racecar and had horrible popping and rasping sounds SCREAMING at you from all angles. I actually had to plug my ears while I was driving when he took off. You wouldn't think that a motor that makes 350hp would sound so horrible with such a free flowing set-up. If you want loud I would get the loudmout, but I would run a cat or weld another resonator in the I-pipe to dampen the brutallity of it.

The hooker cat back system looks good but is it a 3 inch y-pipe? And how does it sound at idle and at WOT?

It has a 3" piping all the way back. it does not come with a y-pipe. You already have that on your Hooker 2055's and that is 3". You just need to fab up a 3" extension pipe to go from your y-pipe to the cat-back.

The best flowing would have to be the borla with no plate. Basically it's like having a cutout. Second would be the loudmouth seeing as it has no muffler at all and just a resonator. The rest are probably a toss up.

Here is a pic of my hooker cat back where it connects to my y-pipe. You can see where it reduces from 3" to 2.5. My y=pipe is smaller than the cat back and cat so there was a need for a reducer.

Cool. Geez your car seems low. I used to have a reducer from the hooker y-pipe to the stock cat before I just cut the cat off completely and replaced it with a 20 inch section of 3inch pipe. Seems like the hooker and the flowmaster systems have mandrel 3 inch pipes the only difference is the muffler. How does an aerochamber muffler compare to the 80 series?

Best sounding I'd say Flowmaster, best flowing is usually Dynomax.

Well..... with price not being an issue at all, the Mufflex 3.5" or 4" systems will blow away (ba-dump....tssshhhhhh) any 3" system....

You can purchase directly through them and have it shipped to your door. They offer those single outlet (do not bother with a crossflow if you want the best flow possible) large diameter systems with Flowmaster or Spintech mufflers.

You may want to rethink that. There is a guy in town here that has that exact set-up on his 2000 SS and it sounds HORRIBLE. It is louder than a top fuel car and sounds like 50,000 fart cans in your ear. It is not a tuned or mean sound. If you go with no cats and long tubes get another cat back that will tune the sound. A cutout sounds awesome but that set-up sounds no where near as good as that. If that helps any.

Best sounding is without a doubt the Hooker. It's 3" all the way back with a dual outlet for the classic look. I would recommend it over the crappy sounding drone of the flowmaster and it's far cheaper than Borla.

For the price, you cant beat Hooker. Great sound at WOT and improves over time, good look of the 4x3inch tips out the back, and great flow. But for the price, a moddified LM from SLP is probably the best flowing as there is no muffler or anything, just an enlarged 4inch section of the I pipe. Flows are fine, but everyone and there mother has them, and they dont really master any kind of flow, for third gen and 4th gens away. If you want stainless, and cheap, PM subzero and get the p/n for the Banks Cat back. Its 3 inch all around with 2.5's out back. I belive he said he got it for something like 260 shipped? You need to talk to someone that knows about it at banks as they dotn show it on there web site and most peopole there dont know about it unless you have a p/n. It all comes down to how much you wana spend.

People........ shut up about what sounds the best. That call is entirely proprietary to the owner of the ear a given exhaust sound is entering .

The best flowing is the biggest system you can get and, in this case, given that we are talking about mail order, that is the 4" Mufflex. Period. End of story.

Agreed 100% if you have a big block with a supercharger. Otherwise you'll have an incredibly loud hollow sounding exhaust that is better suited for the strip only, whereas a 3" system is at least streetable. I don't know about you guys but I'd prefer my street/strip car sounds decent while performing great. But then, that's just me. I don't like attracting too many cops when I'm cruising down mainstreet.

You don't need a big block to need big exhaust. I personally know of many, many small blocks that make more power and move more air than some blown big blocks. It's totally situational.

Over 3" is unstreetable???? I drive my 4" on the street primarily and I know of at least two more in my city that do as well. And how unstreetable are all of the other types of vehicles running around with DUAL 3" systems?????? My 4" single is no louder than my 3" American Thunder system..... It sounds entirely different but is really no louder.

The bottom line is the guy asked what mail order system flows the best. The answer to that question is one of the 4" systems. Most of you...... well....... are pimping your favorite products or mixing in a defense for your lack of using the best flowing exhaust possible. Not to be harsh, but there it is.

Fact is every 4" I've heard on a small block sounds just as loud as running open headers except more tinny. If all you're looking for is flow why not just run uncapped long tubes? Same ground clearance plus it's cheaper and sounds better than a 305 through a mufflex 4".

You have got to be kidding me. That is a blatant lie. I've heard more 4" Mufflex systems than I can count .... and none of them ... none of them were even close to being as loud as open headers. Open headers are freaking loud ... way way louder than a 4" Mufflex.

Me and other guys I know have ran 11's and others I know have ran 10's with a 3" setup. The ATR Performance Pit Bull cat-back setup has had people go 9's with their 3" setup, http://www.atrperformance.com/index.php?cPath=2_24 . Alot of Turbo Buick and LS1 guys I know love the ATR setup. It's a nice all stainless cat-back with a pretty mean sound. Futral Motorsports' site I believe shows a video of their 10 second car with the ATR setup. http://www.futralmotorsports.com/ss_mods.htm

Wow, i like the ATR set-up. Sounds good, eh? I was looking at the Banks, but appenantly the 3rdgen sysrem is backordered right now...or something like that.... ....the ATR is a little pricey. I like the stock turndowns though...

Only if the motor needs it. I think the size you're suggesting is too much for his setup

People, let it die. I "bottom lined" this topic already and, given the subsequent replies, I have to say that I did indeed hit the nail on the head:

I have heard that cross flow mufflers are more restrictive than sraight though ones, is this true? I really want the Hooker cat-back but not if there is a better flowing one out there besides a 4 inch one.

Any straight through flowing muffler will outflow a crossflow. Pretty simple concept, there are less turns to make, thus they flow more.

You can get single outlet systems with straight through flowing mufflers in pretty much any size you want. Flowmaster sells a 3" and Mufflex has 3.5" and 4" systems...... There are likely others but those are off the top of my head .
