Mufflers....cat backs.... resonator... Oh my!

[Happy Hummer]

I'm toying with the idea of a all new stainless muffler, pipes etc...
Many choices and many price points. Stainless is a must as WI. winter's destroy everything.

I've read a lot, watched videos and listen to sound files. I luv the metal malitia sound or cherry bomb sound but I definitely need long term quality and durability in a new system. I like dual out and really like the dual black tip look of Metal malitia.


What are some of the things you like about your chosen exhaust and maybe some not so good things????


NO fart cans, rice burner and hack jobs LOL! I also need to pass picky emisions standards so no deleting stuff. It must all be in it's right place... thanks:thumbs:

So is it cheaper to invest into quality stuff or change it more often with cheaper materials?

I ran Borla stainless steel cat back on my non-offroad pavement queen I5 and it broke in two places within 3 years of installation. The oem steel piping still holding fine!

Hmmm interesting.

Imho I believe it is much cheaper in long run to invest in quality up front. I've tried replacing stuff with cheaper items and it usually backfires.

Talk to friends and find a good shop. No reason to necessarily replace everything cat back. Removing the resonator creates the drone noise. I would replace the muffler and with something louder and have them build your dual tips.

I bought a borla muffler and had a muffler shop build me a dual exhaust system. It ended up being cheaper and I had them put the muffler parallel to the drive shaft instead of just under the bumper so it wouldn't get torn up on rocks. It's the same place that the Gibson system puts their muffler. I think I paid about $400.

Magnaflow 16630 Stainless Steel 2.5" Dual Cat-Back Exhaust System

I've had the Magnaflow 16630 Stainless Steel 2.5" Dual Cat-Back Exhaust System for a few months now and really like it. Best sound I've had on the 3.5L.

If you look around you may find them under $550 and free shipping.

I don't think you can go wrong with the Magnaflow.

Thanks!

I have a magnaflow cat-back system on my Alpha. I like it - personally, I like louder - however, this is my DD and there's lots of times where it's nice to have tame.

RE: Magnaflow - For those of you that have it, any drone at freeway speeds?

 

[Ordieh]

I have Magnaflow on both my CE and my ALPHA and there is absolutely no drone with either one! Beautiful welds, perfect fit and a noticeable performance improvement (I personally think most of the improvement comes from replacing the flattened left bank crossover pipe with the mandrel bent 2 1/2 piece).

 

[K0PIR]

Drone, no I don't believe so, not even up to 85mph.

Gfbh3t runs a GM performance system on Big Red. It's the best sounding 5-cylinder H3 I've ever heard. Deep & throaty but no drone. Just heard it last weekend at the Badlands, doing full-throttle climbs in the dunes...still sounds great.

 

[SuperBuickGuy]

no drone.

 

[Happy Hummer]

Well the muffler your talking about does get quite a good review 4spfunk. I saw references to it frequently but as with most things pertaining to our beloved Hummers they have since discontinued the oem variation. I know there is the original manufacture who still makes them but wow! lol the prices are steep.

I used the Metal Mal just as a reference point to kinda pass along the sound id like to achieve.

 

[4speedfunk]

When I said it was the best sounding 5-cyl I've ever heard....You must realize the GM 5-cyl is a god-awful turd of a motor. It will always sound like a fart but at least you can change the pitch of the fart somewhat with a good muffler.

I'll be posting some off-road vids this week that I shot at the Badlands. Pretty sure I got some footage of Big Red...maybe with some decent audio.

The GM performance muffler is a nice sounding muffler on the I5. It is actually louder than the GM performance for the V8. It does drone at 60 mph but not too loud
