Magnaflow 3rd gen Cat Back

Other users found this on magnaflow website http://www.magnaflow.com/02product/s...erican&id=1514. I called them and it will be available in 8 to 10 weeks from them. Just thought some of you would find it interesting.

Re: Magnaflow 3rd gen Cat Back

I bet once it hits the discount sites, it will be significantly cheaper too...

Re: Magnaflow 3rd gen Cat Back

I'm sure it'll sound real nice. I have a magnaflow stainless muff on my bird and behind some LTs it sounds wicked at WOT.

Re: Magnaflow 3rd gen Cat Back

Very cool. How did you get your hands on that? Looks very nice. You don't happen to have a sound clip? Hoping that they are a little faster than their estimated 8 to 10 weeks. I have a bad case of spring fever.

Re: Magnaflow 3rd gen Cat Back

My guess is that he volunteered his car to magnaflow as a jig for test-fitting.

Looks real nice. Even though I totally dont like the sound, I cant argue with an affordable satinless catback.

One thing I dont like - tell them to loose the "tip inside of a tip" or "intercooled tip" or whatever it is. I just like a single wall, stainless, slash cut tip.

Re: Magnaflow 3rd gen Cat Back

High flow catalyst equiped mandrel bent stainless steel manifold pipes are will be available as well.

Here is the 1990 dual catalyst configuration. 22% increase in total flow capacity and should be hitting the dyno early next week.

Re: Magnaflow 3rd gen Cat Back

I am dropping my Formy 350 off at Magnaflow's headquarters on Monday for the Prototype L98 Single Cat system. They're even paying for my rental car the whole time they have it! Check out the Southern California board here:
http://www.thirdgen.org/techboard/so...e-exhaust.html (free exhaust)

We've been talking about it for a few weeks now

That is very cool. When you get it back if could post a sound clip that would be great. Does anyone know if the 305 camaro is a member here on TGO. I have a Stock 305 and would love to here what this will sound like. Congrats again on getting the free exhaust.

Re: Magnaflow 3rd gen Cat Back

Maybe you will get your car in one of those "click here to listen" videos on magnaflows webiste!!

When I get headers like 2055's or something, I will have to pick a 86-90 TPI system with 3" I-pipe, so that would be great. Will you ask him, when you see them, if they plan to design a different muffler that might be "louder" or something, because the crossflows from the 4th gens dont seem to be any more loud than stock, when used on a GEN I. Also, are they going to keep the weird tips like in the picture above?

I think this will be a good move for magnaflow, because flowmaster just jacked the price of their system up to like $450 on all the websites. So, with the magnaflow retailing for a little less than that, and being stainless, it will sell good I bet.

Re: Magnaflow 3rd gen Cat Back

I heard from a guy that dropped his car off before me that I'll get to choose between the round tips pictured or those rectangular z/28 tips. I might be leaning toward the latter...I kinda like those.

But yeah, I'll find out what I can while I'm there

BTW, you're making me want to redo my sig

Re: Magnaflow 3rd gen Cat Back

Just one guys humble opinion but the Z28 tips would be the way I would go. thats my When you are there it would be interesting to know if they plan on offering both styles of tips or if it will come standard with the round tips and the Z28 tips could be had for extra money.

Re: Magnaflow 3rd gen Cat Back

I've got a 4th gen, LS1 built Magnaflow cat-back, with the bullet muffler in front of the rear axle.

TSP Rumbler

Can't decide if I wanna notch my rear bumper cover, and tuck theb tips up higher, and change to a side exit, like Andris's Boom Tube system.

Re: Magnaflow 3rd gen Cat Back

Heres what I expect this new cat-back to sound like. I really dont like this sound, but I will wait untill I hear the new system, on your cars, to pass final judgement.

Re: Magnaflow 3rd gen Cat Back

Oxidizr to you have a flow rating for the catalytic converters used on the dual cat system shown? I know your metallic spun converters are close to 600cfm.

Re: Magnaflow 3rd gen Cat Back

I forgot I had a video. 160,000 miles, L98,700R4, new cat at the time of cat-back install.

I must say, I wasn't very thrilled with the way it sounded at first. But as everything "broke in", I liked it more & more. The video shows the way it ended up sounding like.

Ignore my neighbor's car in the background......

Re: Magnaflow 3rd gen Cat Back

Stephen, the texas rumbler sounds pretty good. But I dont see how it is comparable to this new magnaflow system, which is completely bolt on.

IIRC, the TSP is 4th gen only, right?

Yep. 4th gen. Mine is a LS1 version.

I like the flow design better than the stock-style crossflow muffler in the back.

Re: Magnaflow 3rd gen Cat Back

Yeah, but I dont have a welder yet, and I am sure lots of people dont either, so that is a non-option.

It does sound pretty nice though. kinda like a cheap SLP loudmouth. What kind of muffler do they put in the I-pipe?

Magnaflow Bullet.....That's why I posted.

As far as I know, only the hangers need tweaking for LS cat-backs, no major mods.

Re: Magnaflow 3rd gen Cat Back

It would make more sense to get the whole cat-back. They use stainless 3" mandrel bent pipe, and by using their I-pipe, no tweaking will be necessary.
