It's loud. Really loud. Here's my setup

Berk intake
Frankencar midpipe
Stillen Y pipe
Custom 2 1/2" catback.
24" glass pack (resonator)
Fucuz muffler

What should I replace? I called the shop and asked why they used a glasspack instead of a regular resonator and he told me that the ones they have use more internal packing so they are the best.

Do I need a new muffler? Or resonator?

 

sometimes a high flow cat smoothes things out. or you should have stayed with the oem muffler.

 

reinstall the stock resonator if you still have it.....Bruce recommends that ya keep the resonator if you get the ypipe
do you still have it??

I have all of my stock parts in a box in storage!!!

 

Yes, I have everything still. I am either going to do that or put the stock muffler back on.....

 

replace the glasspack with stock resonator and replace the focuz with flowmaster 50 series...

 

The best thing instead of all the recommendations is to add another resonator.

We have room for it.

The best would be to put two resonators about 4" apart from each other, and make the first one like 18-20" and the next one 10-12".

Believe me it is better than putting on 36" one, it is the whole sound deadening concept to put two on there and space them.

I concur.

A 3-chamber 50 or 60-series(quiter) for ~$90 would be my first change. I doubt the resonator will do much without changing the muffler.

My friends '67 Camaro with a medium built 327, headers, and exhaust was tamed PERFECTLY with a Flowmaster under regular cruising, but SCREAMS at WOT.

If it can quite that beast, it should make your Max sound like a kitten.
