Title: Replacement Muffler
Post by: Buca on April 07 2011, 11:16:31 PM: As the subject says, I'm looking for an aftermarket muffler to replace the factory muffler. I'm not ready to replace with an aftermarket exhaust system, everything is in great condition except the muffler.

Thanks in Advance

Terry

Post by: Steve Wood on April 08 2011, 07:38:18 PM: I believe this is the right one, but you need to check the length of the current muffs as well as the pipe size.

http://www.jegs.com/i/Dynomax/289/17283/10002/-1?parentProductI d=744882

this version is 14" body with 2.5" pipes

same with looking up the magnaflows...n eed to know the body length as well as the pipe sizes

all the ones I mentioned above are basically the same design. The Aerochamber is quieter and made differently.

the Maximum Flows are from Hooker and are also straight thrus like the ultras etc, but is not stainless. I have had a set of them on one of my cars for about ten years. they are cheaper..or they were because they are not stainless

Or has the criteria changed?

You are correct, I need one that will fit in the stock location...... . Guess I'll take some measurements tomorrow....

Post by: Steve Wood on April 08 2011, 11:24:24 PM: I am not too respectable if I cannot even read simple English

I wonder how close this one comes to fitting?

As far as tuning, there is really nothing magical about it. I think Shane (blackgn) is in TN, but, I forget where.

If you have at least a scanmaster, a TT chip, fuel pressure gauge and a boost gauge, we can help you. If you have powerlogger, it will be even easier.

Other than optimizing the fuel, there is not much to it once the car is running properly. Most of the cars I see data from to tune have basic problems more than major tuning problems.

Steve, what's the closest match on the market today for the Pitbulls that ATR used?
Title: Replacement Muffler
Post by: Steve Wood on April 09 2011, 09:34:18 AM: I don't know....I never saw how one was made.

The straight thru style with no internal louvers are the best flowing available. I suspect that if one flowed them all on the same bench that one would find the only significant variation came with pipe diameter.

Cheapest for that Walker PN is Rock Auto - $90.95, and there's a $30.00 Mail in rebate too.

I don't know that you will find a specific, OEM fit 'performance' muffler. Not sure though.

Post by: SuperSix on April 09 2011, 10:43:39 AM: Flowmaster makes a similar one - pipe diameter is 2.5", not 2.25 as stock though.

Title: Replacement Muffler
Post by: Steve Wood on April 09 2011, 01:26:22 PM: the one thing that should be mentioned, if not done so already, is that the factory system is 2.25" and somewhat restrictive... .the exhaust is usually one of the first things to be suggested to be replaced as it will allow the car to make more power and spool faster.

I've heard guys running 11's with stock exhaust, this is why I'm sticking with stock for now. I'm just looking for a Quick street car is all, after all i'm 43 I don't feel the need tobe the fastest anylonger. Just a nice quick car, Here is what I've had done so far.

Kirbin Springs
New Timing Chain Set
Rebuilt High Pressure Oil Pump
42lbs injectors
fuel pressure Regulator set to 42lbs
FT Extender Chip-set for 20lbs of boost 93octane
3'' MAF & Translator
Scanmaster
CAI
Walbro 340 pump and Hot Wire kit.
Running colder plugs, onestep down
New wires also...
Along with new paint,Brakes, and all fulids......
What would you do for the Next step?

Post by: Steve Wood on April 09 2011, 03:50:00 PM: Damn, I was 44 when I bought my GN new in 1986. LOL

I picked up a bit more than a pound of boost by swapping out the stock exhaust.....

Alcohol injection....h ands down :) It might get a bit more out of your stock turbo...it will get a lot more out of a TA49, but...

and I am mad right now because I got in the two tie rod ends I needed to finish off the suspension rebuild on my Challenger and someone stuck a ford end in one of the boxes so I can't finish it today...LOL

There should be some substitute (legal) for women and cars!

I am reworking the Combination page on my site...down at the bottom I offer some sample combinations.. .you might look at them for ideas?
Title: Re: Replacement Muffler
Post by: Buca on April 09 2011, 05:01:29 PM: Women should not work in parts stores, all they do is get the part the computer tells them too........ If they looked at them, they wouldn't know the difference from a tie rod or a balljoint..... ..

And yes I was thinking Alky Next.......... .

Post by: Steve Wood on April 09 2011, 05:28:58 PM: there are a bunch of women cross dressing around here, then...cause that is all most of them do when I go to the parts place....I have long learned to try to find the right number before I go....

One other question sence you're so well known, would you happen to know anyone in or around the nashville area that could tune my GN for me?

There is a guy in Shelbyville that is very good with these cars. He's a bit old school though, no computer, no internet, I don't think he even has a microwave...an d unfortunately he gets a little behind the times in regards to some of the newer technology out there for our cars (ie powerlogger and some of the newer generations of alcohol systems). But I trust him completely with my GN and I'm borderline OCD about my car.

This is him on an old Motor Trend Classics show:

http://www.youtube.com/watch?v=9Ja4Ffcr8n0

My car has been on that very same road a few times for test runs.
