I checked out the J.C.Whitney site after looking into the Cherry Bomb idea on the Maremont site.
The J.C. site had some information on it that prompts my next set of questions:

1. I'll want to keep the 2.5" ID to maintain the factory exhaust diameter, and there is a choice of case diameter, ID, OD, and length of these straight through mufflers.
In order to maintain the 2.5" flow through, I'd have to go with a 4" case.
Is this going to fit under the car?

The choices.

http://www.jcwhitney.com/item.jhtml?ITEMID=3904&BQ=jcw2
The one I was looking at for my car.

2. What IS the diameter and length of the case of the factory resonator that is on the later model Bonnevilles?

Once this is determined, I can select the appropriate item and have it installed.
I'll have to do more research on the Cherry Bomb unit. It'd be kind of fun to have a real 'old school' muffler installed ahead of the latest 'high tech' stuff, all in order to get the sound I'm looking for.

looks like part # 87516 is the one I'm looking for.

And another link to a Saturn project that the guy used a Cherry Bomb glasspack in place of the resonator, so, I guess I'm not the first to think of it this way! Good.

Whatta maniac! :P

I await your wisdom and knowledge, guys! Thanks.

Well if anyone is interested my car growls pretty good. Sounds like a slightly tame flowmaster you'd hear on a mustang. I've looked at it and I can't see what kind it is but I'll do more research into it if anyone is interested. Like I said I frequently set off car alarms when I rev or start it. I hear a constant hummmm in the cab when I'm driving. And no there isn't an exhaust leak.

My stock muffler did have small leak, plus the stock tips were missing when I got the car.
I chose the MagnaFlow for it'* stout construction and the minor difference in price for the stainless looked good for the constant wet weather around here.
The tips were just right, too, for the weather conditions and the size/fit for the application.
I almost chose the DynoMax muffler, but, I've had them on another car and they had a terrible moan to them. There is no moan with the MagnaFlow, only a certain "BLAT" sound at the aforementioned rpm range.
I'm hoping to eliminate that with a substitute resonator.
I e-mailed the guy with the Saturn to see what his comments might be.
Truly, this is a fun project to mess around with because it'* different than any approach I've seen, plus the fact I had no idea any further modifications would come into play.
What the hell...it'* only money!

OK, guys, here'* my question and the reply from Joe:

Q. Sir:

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.
Thank you.

Sincerely,
Trevor

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

Joe


It'* a GO!
