Go to Autozone and look in their performance catalog...

You can special order the Firebird/Camaro crossflow mufflers.

Magnaflow for $80.99, Dynomax Super Turbo for $92.99, Flowmaster you can get from practically any muffler shop.

Perhaps you haven't read the entire thread. This is a new exhaust system. Everything except for the header pipes (collectors) have been replaced last year. Please look at mods list before posting.

Not true! If they flowed the same, who'd spend the extra money for headers? Depending on how far you want to take the car should be a factor on whether you get headers or PEM'*.

I don't know what to tell you about that sound, are all the exhaust connections tight?

Let'* be reasonable here. People spending money on something is no indicator of whether it gives a significant (or any) performance increase. Just look at any Honda Civic with a big fat wing on the back. If we use your logic, those wings must add significant horsepower, because otherwise, people would not spend money on them.

I don't know (or care) why people spend their money on things that don't make any real performance differences on their cars. Maybe they just like spending money. But the performance of PEMs has been pretty well covered in several threads. I believe people have even done dyno tests before and after headers, and before and after PEMs. If I recall correctly, headers gave a small improvement, and so did PEMs.

People also spend money porting their exhaust manifolds, and it'* been fairly well covered that Bonneville exhaust manifolds breathe pretty well, especially if they're ported. Headers might be marginally better. But Bonneville exhaust manifolds perform very well as well.

So I stand by my advice that PEMs ultimately perform similarly to headers. Headers may perform slightly better. The differences are probably small. Even small differences are important to some people, so headers may be worth the extra cost to them.

But price has never been directly correlated to performance, and price alone is no reason to judge one product better than another.

As I suggested originally, people here who have them would be better equipped to give their experiences with them (both headers and PEMs.)

[quote="chadow427"]Yes. I went to Midas and they put the car up in the air and they showed me everything was rock solid...no movement, no visible leaks.

It'* normal under idle and in park (throttle up and down). But when I have it in drive (brake torque) the sound is loud...almost sounds like the exhaust gases are rattling around inside the resonator. It'* never been this loud before. I suspect there'* something going on w/ the resonator.

Being that adding the exhaust was a P&B thing.. this thread belongs here. Although pulling it back up after a year to ask a mechanical question isn't the best route to go. I'm requesting the mods split this up so that we can get you the best answers and help in the 92-99 mechanical problem section.

Found the problem. The front transmission / motor mount was broke causing excessive travel / rocking of the motor, which caused the excessively loud exhaust noise around the firewall area. $280 later, she purrrrs again. Now I have a more consistant torque and feels like more boost (the factory gauge burries past 10 on WOT).
WOO HOO!!!

You got ripped off. Sorry. That front mount is cheap and easy to swap. Keep in mind if that were actually the problem, you'll be changing your downpipe exhaust donut very soon. It'* probably beat to death. Unless that was included in the price you paid.

I think the price is semi reasonable. The mount is at best $100 and then figure an hour or so for labor. The garage made money..but it'* not obscene like some of the repairs we hear about.

As mentioned..keep an eye and ear open on the exhaust.

Downpipe was replaced 8 monts ago. Only place that could get one was the dealer for $180 plus labor. Hopefully, no major damage was done. Time will tell.

I was told by a buddy who no longer owns a repair shop that his price on the mount was around $120. The mechanic at Midas said it was a pain in the *** to replace. Probably not something I would ever dare to take on myself.
