Magnaflow questions.....

[kcshaner]

The new car I purchased has this Magnaflow exhast MagnaFlow Performance Exhaust - For American Muscle Cars
In this picture it shows the exhaust and also two straight pipes...I am guessing that replace the resonator in the middle of the exhaust. I would like some more sound (the sound is incredible, I'd just like it to be louder) was this exhaust set up to have a quiet or loud version? Can I just weld in some 3" pipes and remove the resonator? How will it effect the sound and performance?

Also, in my quest for added sound and performance I am considering the magnaflow hi-flow cats. First off, how restrictive are the factory cats? Also, the mid pipe on the magnaflow is 3" and bottles down to 2.75". The Magnaflow catback starts at 2.75" then is 3" the rest of the way....is this much of a restriction? Its seems to me Magnaflow should have gone 3" all the way with no bottleneck.

OK, last question I promise. Do any companies make off road mid pipes (no cats) to use on track days, etc?

Put the high flow cats on and that should get you more sound. Others may chime in if they have that set-up. To me, the cat-back is plenty loud.

Here are some magnaflow catback threads to check out. I don’t know if any of them will help answer your question or not. If not it will at least bump your thread back up so that others may see it. Good luck!

i read the threads, i must have a magnaflow...
looks so cool and i would to have that nice sounds on my car. You got the answers already? So what's your plan?

If you want more sound and performance, add a set of Kooks headers to the engine. If you don't want headers the high flow cats are your best bet.
