So i built the catback with dynomax ipipe and over axle pipe, Hooker Maxflow 3" in 3"out and did the rest, i still need to get a turn down mounted up but who cares for right now. here you go. The DynoHookerMax.
The catback sounds great at higher and lower rpms. No drone cruising at 80 its almost like stock with a little tone. at 3000rpm the sound increases dramatically. I'm interested to see if this breaks in at all sound wise. Anyway here are the pics and a vid. Overall. very happy.

 

Sounds decent. Are you just mounting the turn down right at the end of the muffler? I was thinking about doing that because I hate the way my car looks with the magnaflow single tips. I wasn't sure how good of an idea it was to run two turndowns out of the muffler, but I guess its not a bad idea.

 

sounds pretty good. and it's good to see somebody trying something different. i want to hear those mufflers on a true dual set-up.

 

yea, im just gonna do a 90* bend off the muffler and have a turn down towards the back. I love my car even more now with a catback. Also this was super cheap too and definitely freed some restriction giving a little power.

 

Sounds good. From the video it sounds like its louder than my Hooker aero chamber cat back with LT's and ORY and idle. Definitely not at WOT tho

 

according to the muffler shoot-out it was one of the loudest mufflers tested at WOT. But I plan on LT's down the line so we'll see how it sounds then.

 

It looks like you used the center/offset Maxflow version. Correct?

Are the Dynomax I-pipe and over-axle pipe sold separately, or is that from an existing catback?

It seems like this set-up flows well, sounds good, is reasonably quiet, and is relatively lightweight.

 

Cool where did you get the I pipe an over axle pipe (pm if not a sponsor) .I was wondering the diff between the Aero chamber an the max flow. Sounds great i'm looking for somthing kinda quiet driving around town (had a LM1). Do you have headers? cats?

 

all stock exhaust besides the catback. Its quite light too =)

Summit
Dynomax Ipipe WLK-54064 -$49.69
Dynomax overaxle WLK-53061 -$60.39
Hooker maxflow center3" offset3" 67 bux.

 

That is one great sounding inexpensive catback. All you need is a little more 3" pipe for the tailpipe and turndown. Maybe $20. Total $200.

I'm really tempted to experiment with this set-up vs. my GMMG. The single turndown would look good on my Formula, too - or a Z28 like yours.

 

what is the diff in the aero chamber an the maxflow? Sound ,price,etc. and thanks for the part#"s I have a slp muffler an tailpipes w/dual slash tips off of a 02 firehawk. Nice,quiet an all S/S the i pipe an over axle pipe would work great with it.Should bolt right up to my 3" TSP ory Pipe.

 

Sounds nice and healthy. Definitely looking into one of those.

 

unfortunately i havent heard the aero on a LS1 i had it on my 357 vortec firebird, aero that is. So i cant really compare. This is where i got my research from.

Thanks man!!!!

 

no problem just helping the common wealth.

 

Sounds good.

 

I'm gonna try and get a video tonight of some WOT runs and some of the car under load.

 

cool post them up!

 

Sounds great for a car with stock manifolds and cats. More soundclips please!

 

alright i still need to get some runs of outside the car but my roomies and i had some fun last night so i got some WOT runs in my car.

1980rx7 with a 5.0 and exhaust, C32 with code3pulley, code3 intake, kn filters
and my car as a chase car with my roomie and friend(400lbs together...)




heres one you can see how quiet it is cruising.
