Just Installed Magnaflow Mufflers

[Green LT1]

Voorthuist, glad to hear that the Magnaflows worked out for you too. I still think they are a great deal for the money. I love them every time I hit the gas.

Thx pal!

BTW Did you ever pull out your resonator, or do you plan to do so? And do you know if there's an x-pipe available for 95/96?

I wanted to bring this back to the top because I had the same question. My Magnaflows will be arriving on Friday (also from Performance Peddler, $320 shipped). I was wondering about the resonator and the crossover. I figure if I am going to spend the money on the exhaust, I might as well do it all at the same time. Well, except for headers. I've read about people putting the balance tube as far forward as they could, and also as far rearward. What's the scoop on that? I've been told it would be cheaper to order a crossover and have it installed, rather than having a shop make one. Does anyone know of some websites that sell these? Is there really a HP increase w/ one installed, or is it just for less resonance? One more question, anyone recommend a good exhaust shop in the San Antonio, TX area?

Hey Mr. consultant, I purchased the Magnaflows from Performance Peddler( $345.00), UPS dropped them off on my front door, I installed them myself (your were right – about an hour), took it for a ride, then drove it right down to the muffler shop and had them welded up!

I tried Flowmaster two chamber and then three chambers, Borla, and something else that I have now thrown in the reject pile. The Magnaflows have approximately 90% less resonance than any of the others that I tried. Thanks for the input, there a keeper!

Johnny, glad to hear your Magnaflow experience went as well as mine. The weather here is getting better, and I have driven my '96 quite a bit in the last week. I still love those Magnaflows! The sound is definitely aggressive, but not obnoxious. I have had absolutely no problems with the Magnaflows after the installation. As you noticed, the resonance is extremely minor, and is not a problem at all. I still think they are a great deal for the money. I just chasnged my coolant over the weekend, and that was a trip! Now I need to plan a few other Vette projects in the weeks ahead to get ready for cruising on those warm summer days and nights.

I'm also looking to replace my 10 year old dynomax super turbo muffs, but those
magna flows hang a bit to low ...they look akward? Can they be "tucked" up ?
:confused

Yep, they can be moved up. I modified the brackets and the pipe a bit so that the mufflers sit way up there.

Here is a sound clip of my new SS Magnaflow catback.

Sounds sweet ld...was the part# 15658? i found it on there site but it states 86 & up...from readin all the posts i wanna go with the Magnaflow....a speed shop in Cincy quoted $570 but he wasn't sure if it would fit my 85

 

[LD85]

Yes I bought the system for the 86-up and then bougth a used Catalytic coinverter from a vette salvage yard for $45, total bill was $461 including shipping.

You can buy them here for $406 including shipping and actaully get a new cat 86-up, from them for an extra $60

They give you a 25% discoutn if you type vetteforum into the coupon area

This is a Mirror Finish SS catback system, y-pipe, mufflers, clamps...included

Johnny, can you post some pics so we can see how they look? Thanks.

I've seen a few cars with these installed but didn't like the way they looked. The high polish looks great but they all looked like they were hanging low and not a perfect fit for the application. I'd like to see yours tucked up like the stock mufflers.

Sort of a picture

Had mine for about 6 months now. Bought them from performance peddler on Ebay then dropped them off at a local muffler shop. He charged me $50 to install them. Too easy!!! :cool


I agonized a LONG time before buying them. Was really worried about how loud they would be because they are a straight through pipe. I could not be happier. When I first got them I did think they were a little quiet...but after a while they settled into a nice agressive low rumble ...the neighbors will know you are home but they won't throw things at your car.

My 2c says they are the best deal going...yes they cost more than factory reproduction kits but...a SS Y pipe with 2 highly polished SS mufflers and some awesome big SS tips... installed too for about $425...ya can't beat that!!

Magnaflow is local to me...they are having a car show on April 24th...I think I will go and let them know how much I like their product. Maybe I can get Mario Andretti to autograph mine!

Okay, what about the crossover?

Where should it go? I hear that the LT4 has one, where is it?

 

[Green LT1]

Pizzaman, Magnaflow does not offer a catback for LT1 applications, just the mufflers. I do believe they offer catback systems for L98 applications. From what I have read, that is due to the fact that Magnaflow's testing showed very little if any gain in HP by replacing the rest of the pipe behind the cats - the mufflers appear to be the main limitation in flow. If you look inside the stock mufflers and then look inside the Magnaflows, you will see why. I still love mine, by the way. My wife grudgingly approves, but just barely!

I just ordered a pair yesterday. I think they were $320 delivered so I should have them sometime next week. I don’t have a reciprocating saw so I need to find some other way to cut the existing exhaust. I'll then have them welded at some point after that.



What else can be used the cut the exhaust? I think all I have is a Jigsaw and a circular saw.

Wow, $320 delivered sounds like a great deal. Where did you order from?

By jigsaw do you mean a small hand-held sabre saw? That would probably work if you use a fine-tooth metal cutting saw blade. If you're ready for a workout, a hacksaw would do. Getting access to the proper location to cut will be the issue. Whatever you do, wear some eye protection from the chips that will be flying.

I'm not sure if the LT4 has it, but it should be after the resonator & before the spare tire. (tube going from one side exhaust pipe to the other)

I ordered it new on eBay. I'm sure another one will surface again soon .
