What kind of Exhaust should i get?

[96FirebirdFormula]

You dont need am install kit. what does that consist of? Call up Summit.

P.S. Get the Loudmouth I and maybe down the road an off-road y-pipe or a RandomTech Y-Pipe. Thats what My brother ran and let me tell you, It sounded SICK!!

Here what says need for install

Just a note about flowbenches and muffler testing. Flowbenches use a vacuum to measure flow, works great for testing an intake runner, but it is lacking when testing a muffler. Flowmasters work great. They flow worse than a straight through type when a vacuum is placed on them, yes. Exhaust doesn't work that way. It is forced through, not pulled through. The expansion of gasses that a flowmaster offers is where they make power. The vacuum of a flowbench simply cannot duplicate this phenomena.

That said. I started with a flowmaster catback on my 96, then got the stainless works offroad y-pipe(mild steel), then got the slp shorties. Imho the fm catback and the mild steel sw ypipe is the best bang for the buck setup out there. mix that with the new pacesetter shorties, and you can have a full exhaust for about the price of a borla or corsa cat back. I ended up selling the fm catback, and running a 3.5" dynomax bullet with a turndown. That is surprisingly quiet cruising at light throttle, and the turndown under the car gives a very deep echo. It also saves a bit of weight.

Lastly, if you are planning on a bolt on type car, and not looking for every .01 in the 1/4, get what sounds the best to you. In the end, you are the one that has to live with it.

What is differents in Loudmouth I and II

[lsdengines]

loudmouth 1 is an empty cannister that looks like a muffler. Im not kidding, cut in half it is a bullet type muffler with no packing, and the core tube cut short at each end. The loudmouth 2 is pretty much like any other bullet. It is a straight through perforrated core with a sound attenuating packing material around it.

You dont need am install kit.

What in the world makes you think that? There's a reason the install kits are sold. The LM kits are meant for the LS1 cars, which obviously have different hangar locations than either of the LT1 setups. Hence the install kits.

If you're going with a LM, get the install kit. I did for mine and it made the install a breeze.

[raroZ28]

get the magnaflow, you will not be disappointed.

[Nightrage]

i want it loud we got no emissions here

Go with GMMG. It's loud...really loud.

I personally prefer not to tell the cops that I'm coming from a mile away, but that's just me.

My Mistake bro. I have an LSx so I guess it can be different. I just remember that when I got my system from Summit they never said anything about the Install Kit. And My system was a Breeze to install.

I think that in order to answer your question best, I would have to ask you a question or two first.

1. What type of tone quality do you like?

2. Is this a daily driver?

3. If a daily driver, what is the driving routine? City? Highway? Speeds?


The reason I ask is that ANY exhaust system that allows more noise than factory, does so at different rpm ranges and depending on the combination of automatic vs stick, city vs. highway can be a royal PITA.

As an example, my 4" mufflex at less than 2000 rpms was quieter than my borla. as soon as the rpms crossed 2000 she began to bellow until above 3000 rpms where it settled down. In an Automatic car, the exhaust is barely tolerable. In a stick car it has a different personality.

Magnaflow for the price for the quality and lifetime warranty. Sound is burbly and quiet during crusing.

If you had money to burn...Corsa all the way. Sick sound and top quality.

It's Daily driver. i only drive about 5-10miles a day

I run a magnaflow catback, good flow, sweet sound. Loud enough to hear it coming a couple blocks away, but not so loud you need ear protection. It does prohibit cell phone usage while the car is running, especially with the tops off or windows down, but you shouldn't be using a cell phone while driving anyway. It's not cheap, but then again you get what you pay for.

This site let's you preview the sound of many exhaust set up's on a range of different f-bodies.

I've had Flowmaster, Hooker, and now Magnaflow.

Magnaflow and Hooker are very similar except Magnaflow is stainless.

I prefer the Magnaflow setup. They work fine as far as power goes (just like all the others really) are stainless for long life, and have great sound. It's more of a refined sound. It's quiet while cruising but is loud enough to hear a half mile away at WOT.

Magnaflow is the best value in my opinion. Magnaflow also looks great. I don't like the tips and am currently changing them, but that's my only complaint.

I've never head a LT1 that sounded better than mine. I'm running the SLP midlength headers through the stock cat into a Borla catback with an electric cutout mounted in the Borla's bypass flange. With one finger I can adjust the sound of the exhaust from wide open to fully muffled. It depends on what mood I'm in. I usually open it just far enough that it starts popping, then back it off a hair to make the popping stop. It's loud and throaty, but smooth.

A fellow forum member Kevin has the same setup but no cat and his car sounds like a monster compared to mine. That cat really changes the sound of the system.

I think there's a lot of people confusing engines here. LT1's are so much more forgiving with exhaust notes.

For sound quality on an LT1, I have to recommend flowmaster. I've had LT1 and LS1 cars each with three different exhaust setups, and I'd give just about anything to have the LT1+Flowmaster exhaust note on my LS1 car.

This is assuming you want a fairly civilized setup, enough that people know it isn't stock, but not so much every single person within 200 feet is looking at your car. The interior sound levels are good too, still usable for highway and phone, talking, etc.

If you prefer even mellower, then the SLP 2otl is another good option.

My preferences are greatly biased towards deep, throaty sound, which both of these will give. Probably not shared with the under 20-something set.

Many people just want volume and that's where other setups come into play (Borla, etc.).

If you just want volume, try a cutout. LT1 guys can get away with it.
