OK, guys, here'* my question and the reply from Joe:
I found your webpage on a Google search for Cherry Bomb glasspacks.
I just spent a good amount of $ on my '92 Bonneville SSE'* exhaust system in the form of a MagnaFlow stainless steel Camaro/Firebird muffler part# 14266 and a pair of ANSA stainless steel dual resonator tips part# 7820, plus installation.
The system is good, and it sounds OK. I picked up a bit of power through the mid-range. The problem is that I'm only getting the deep tone at idle and revdown. There'* a spot about 2000-2500 rpm where it starts to get a little loud, and almost 'farty', which I was desperately trying to avoid.
My thought was to place a Cherry Bomb glasspack ( part# 87516 for my application ) where a resonator would normally be placed ( the '92 SSE'* have no resonator from the factory ).
I'm sounding the idea out on the BonnevilleClub.com Forum.
Seeing that you've done this already, I decided to e-mail you and hope for a response as to how this setup worked for you.
Did you gain a lower, throatier exhaust sound?
Are there any flat spots in the power range?
Anything you can tell me to help me decide if this is a good move or not is much appreciated.
A. I have no problem with you posting my response in those forums........fire away!
Using a glasspack in place of the resonator did exactly that. My original exhaust install was without the resonator and it was real raspy ("farty" as you put it). I bought the glasspack and went back and had it welded in...the difference was noticable immediately, and has gotten slightly better as the muffler has broken in (the fiberglass packing settles over time). The best recommendations i have are to stick with a reputable brand like Thrush or Cherry Bomb. Those are perforated core mufflers that cause no restriction in the exhaust path. Some mufflers are louvered core and that creates turbulence. Also, get the longest one that will fit. Measure the pipe from the catalytic converter to the first bend and get the longest glasspack you can that will fit in that space. That should do what you want nicely.
As a side note, exhaust is going to be one of our topic on JBO radio this weekend ( http://www..j-body.org/radio ) . listen in and see if we have anything useful for you
It'* a GO!
