Resonator Options



I put magnaflow on my ss zzp exhaust helped quite a bit on the rasp but still have a drone,but the 3" is what Im thinking makes it drone like it does. Thats with the original zzp mufflers( not quiet)
 
I had a magnaflow res with magnaflow mufflers on my last grand prix, it sounded good but it was too loud for me. I swapped out the magnaflow res for a zzp quieter res and liked it better but it was still too loud. I dont plan on changing my exhaust on my current grand prix, stock sounds best.
 
I used a stock resonator.

With aftermarket mufflers.

And catless headers.

Was quiet enough.

Then I just cut everything off because I didn't care.
 
i just bought the same resonator on advance auto using promo code trt30 it only came out to like 89 shipped......save a dollar earn a dollar lol
 




have not put it on yet i am doing a l67 swap in my gt put a s1x cam and all new gaskets ported the supercharger deleting the egr headers no cat and full 3 inch exhaust all the way back.waiting till income tax time to get a trans from tep so i dont have to drop it twice.....excited to see what in can do
