Default Exhaust!

Hi Guys!
I was wondering if anyone has used magnaflow exhaust on their vette?
I was told magnaflow is a better deal than Borla.
thanks.
Rick

which C4 do you have.. LT1? or L98?

The magnaflow cat-back for the LT1 is not a complete cat back, it's just muffler extersions, mufflers and tail-pipes. You have to cut off the rear portion of the stock exhaust, and clamp/weld these on.

For the L98, the magnaflow system is a direct replacement.

As for which is better.....flip a coin....they both sound better than the stock exhaust.

I had the Magnaflow exhaust (mufflers) on my 6-speed LT1 and the resonance was horrible at low RPM. Eventually got tired of them and sold them.

I have the Magnaflow exhaust (mufflers) on my 92 LT1 and have no problems with resonance whatsoever. I like 'em!

We have one guy that couldn't stand the reasonance and another that love them. You are going to all sorts of opinions in this issue. I asked my Vette mechanic about this and here's the advice he gave me:

Contact a local Corvette club and listen to and ride with guys that have various exhaust systems to see how they sound. Your REALLY not going to know if a particular system is right for you in terms of reasonance until you do.

I installed a magnaflow cat-back system on my '90 L98 automatic, it looks great I and love the sound under power. I don't love the resonance at low RPMs so I shift to a lower gear when the resonance gets too bothersome.
Has anyone solved the problem with a crossover pipe?

You may want to do a search, but I "think" most of LT1 guys like the Corsa exhaust.
