Why would you ask if there is something "wrong" with them? Theyre made for the C5 right? So they should bolt up. Flowmaster has been around a long time so no one is gonna understand your question as whats is wrong with the brand itself. Naturally people are going to think youre asking about peformance and quality. What would be wrong with them other than going with a different setup for sound or performance reasons? If you like them so much, why even ask? There are millions of flowmaster mufflers out there and the way you talk about the price of parts it doesnt sound like youll be modding the car anytime soon so obviously horsepower aint the issue. Just get them already and buy a six pack with the money you saved.

Corvettes are touchy. I wanted to make sure that going with Flowmasters wouldn't affect anything else that would require additional parts, work, etc. I thought it was farily intelligent to check before just jumping blindly into something I was unsure about.

No, I don't, but then Flowmaster's own literature says it gives a 10% increase, and most companies, especially those as big as Jeg's, don't want to get nailed by the FTC for false advertising, not to mention class action lawsuits.

Don't blame me for what they say. I just repeated it. Odds are that the actual benefit is closer to what they say than not.

Did you have to do anything other than just straight bolt-on, so to speak?

One of the easiest installs I have ever done! The tips aligned absolutely dead nuts on.

My car has no drone what so ever, and my friends C5 427 has absolutely no drone!

I went from a stock TI muffler to a TI bypass to this and I expect to die with this system on my car. I have yet to hear a system I like better.

Best of luck with your decision!

I really liked my Flowmasters on the Vette when I had them on -

Eventually I got rid of them because a baffle came loose in them - I have heard this be the case for a few owners - but if getting them new you should be good for a long time!

And they sound real good with the LS1 motors and other mods !

Thanks,Matt

Also, I didn't pay $35k for my Vette, and it was $47k new on the sticker according to its records. A C5 coupe is certainliy not worth $35k either.
The $35k number was just a reference number not meant to be dead on... and of course I know your C5 coupe isnt worth even $25k. Now, on the $2000. for a used exhaust system... LOL!!! I bought my TPIS headers, Random Tech Hi flow Cats and Random Tech X Pipe for $700. right here on this forum!! So maybe a little more investigating might help you. And for the record, there is nothing wrong with Flowmasters products. I run a pair of 40 series on my 98 Chevy pick up and they sound great. Lastly, lighten up man... you asked for opinions and you got them. Bolt on whatever you like on your car, its your car.....

30hp - That is a pipe dream. It's not going to happen. 10-12 rwhp is about the most you can expect from the best complete aftermarket C5 "catback" exhaust system. You're showing a muffler only and besides, Flowmaster baffled mufflers would likely be more restrictive than a more straight through design.

Warranty - Seriously? I doubt you can collect on any possible Flowmaster warranty once they are installed.

If you think you'll like the sound then get them and install them. There is no other reason to use them besides liking the sound. The car will still work fine with just about any reasonable catback change you can make so I wouldn't worry about that. Changing the rear piping and mufflers just doesn't cause enough of a change to throw-off the fuel injection.

people on a tight budget have always figured out how to beat the system and get the same thing that others have paid much more for at a lower price

good luck with the 30hp increase drownmasters

I didn't know Corvettes were .... touchy

must be because it's so easy to add hp from installing mufflers

sorry

It's not false advertising. Misleading advertising. 30hp - I can maybe see that if we're talking about a 1000hp car, switching from stock (maybe even a broken stock muffler) to a flowmaster. But on a stock, or even simple heads/cam car, it's probably more like -5 to 5 hp. I don't know the design of the non-Ti mufflers, but I know that the internals of a flowmaster is junk.

If you're buying parts based on manufacture HP claims... oh boy.

I have to disagree with that. It is not industry standard for performance aftermarket exhausts. It is the exception and only found on cheap exhaust systems. The "industry standard" is 300 or 400 series stainless steel. Even cheap cars now come with stainless steel mufflers.

They will rust out and it will happen faster than you think. It's just that most owners don't realize the damage until they start to hear rattling. That's because the first parts to go are the baffles on the inside of the mufflers. This will happen quicker with owners that do not drive their cars frequently or on very short trips.

In the end, the OP seems to have made up his mind and will probably buy them. But at least he is now better informed. You get what you pay for. There is a price for quality.

What part of "no I don't believe it" don't you understand? Feel free not to act like a jackass and please move on to the next thread. Obviously my initial question is too complicated for you to understand, so take it elsewhere junior.

School must be out.....

Thank you for this response, and thanks for answering the question. It's good to know that there are at least a few grownups around.

As I said before, I live in Texas. Things don't rust here unless you leave them sitting in a field for a few decades.

Actually, no, I haven't. The only thing I have made up mind about is NOT to do what everyone else does. I'm not a sheep.
