Can anyone explain why a cat back is more desireable than just a muffler replacement? I had a Corsa installed in my first h2 and aside from the sound, I didn't really feel a damn thing. I had just a muffler replaced in my Tundra and same thing.

The reason I ask is that $700 for a H3 cat back seems unreasonable when you can get a cat back for a H2 for as low as $400. I know it's a market issue but what's wrong with throwing on a 40 series flowmaster for $250 intalled?

speaking from experience you dont wont a flowmaster on your H3.The outside noise sounds good,but the inside cabin noise is very annoying.I have the SMA exhaust now and the inside cabin noise is 90% quieter than the flowmaster.

Nonsense, poopy pants. It's not likely to get old any time soon.

Ken is right- how'd you determine the exhaust "noise"(you must be ghey if you think it's noise) is "90%" quieter?

Hey smart ass's I have these thing ,you may even have them yourselves they are called EARS. I have had both systems in my H3,so I think that makes me Qualified to make my assesment of noise level.Nice to be surrounded by such Sexual Intellectuals,or as I like to say #$%^^& know it alls.

Kacyk,
Go with the flowmaster or leave it stock. You are right, for the price, you don't get your money's worth out of swapping the entire CAT system.

First Hummer,
Got a question for you. If the flowmaster emits lets say 40 decibels of sound from outside and the SMA emits 40 decibels from outside....how can the inside sound be 90% less? OK, I get that the muffler may have some shielding on top or something, and that they may have different frequencies, but come on, the H3 isn't exactly the quietest ride on the road and any significant sound increase is going to be apparent in the cabin as well. And since we can assume that any performance gains will be minimal with either set-up, why spend the extra jack on the other system that will probably get bashed up when off-roading anyways? Just curious, because you have to be into exhaust upgrades for over a grand already and seem to have some very odd OPINIONS of the differences.

My fault you guys are correct there was no siginifcant noise change from one exhaust system to another.What was I thinking excuse me.

I'm no expert but if a cat-back comes with a resonator, does that fall into the realm of possibilities why it would sound quieter inside?

FLYINGBADGER2006 09-28-2005 04:07 AM

My dealer was offering a intake and exhaust package for $1500.00 Thats the SMA Air Intake with box/shroud and the Magnaflow (cat-back) dual exhaust with chrome "tips" complete muffler kit installed.

Unless you're desperate I'd wait. On our H2 a cat back can be had for about $400 or less and a K&N FIPK is around $250. Even with install on both units you're still under $1,000.00.

I think the Magnaflow cat-back is available for the H3 (or it will be soon) and there is a K&N intake system for the H3 as well. you can have both for under $800.00. Install the K&N yourself and have a local shop install the muffler. Save yourself $500.00!

FLYINGBADGER2006 09-28-2005 11:11 PM

Sounds like good advise to me. I'll keep my eyes open for any info and deals. I'm hoping that Borla will come out with thier system. Even more so, JBA header or a modified header.

MyxH3 09-30-2005 02:05 PM

I was wondering the same but after reading all these posts. Flowmaster is looking pretty good to me.

kacyk 10-01-2005 07:38 PM

Magnaflow Sound Clips

I hope someone comes out with something that sounds better than that! Perhaps it's a 5-Banger issue but heck.

FLYINGBADGER2006 10-01-2005 09:41 PM

Can anyone tell me how much this Magnaflow cat-back dual exhaust will cost? There is no price.

http://www.stylinconcepts.com has prices.

OK, I have gotten SOOO many emails about where to get my "MEAN" exhaust! So here is the information you all want to know...

Let me make it clear that this sounds DEEP AND MELLOW, not Loud and Obnoxious.

1. The guy at the shop claimed a 7-14 HP difference, and I think I got a gain within those numbers.

2. The best part is that if your windows are up you don't hear much, and when they are down you just hear the "deep and mellow" sound... You see, the thing is that I tried on 3 different mufflers (magnaflow, Dynomax, Remus) and the best sound was the Remus (most deep and mellow).

3. What's the equipent? I got the BEST muffler on the streets: Remus (German Made). Also, there is Aluminized piping, and the tips are all AAA Stainless Steel High Polish with Chrome (these are the only tips that wont rust or change colors quickly)

4. The cost was $920, but not everyone can get that deal. I called up the guy at the shop and he said that he can arrange that deal for all you people who go there and state my name (Ely).

5. This includes installation and LIFETIME WARRANTY

6. Dont forget that you're buying top quality equipment.

hmrlvr 10-07-2005 09:19 PM

Yea but do you think the TIPS will get torn off when off-roading?

sltbluh3 10-08-2005 11:37 AM

When I bought my H3 (sept 12th) the dealership put on the cat back exhuast, air raid cold air induction and throttle body spacer. They quoted and add of 41 hp. I test drove a std equip'd and a performance equip'd h3 a major difference in take off. Also I'm getting 19 mpg back and forth to work the add ons so i think it was worth it.

Ely 10-08-2005 05:35 PM

Although I don't do off-roading that is as extreme as some of the videos posted up here, my pipes have not gotten in the way of off-roading at all. In facts, the tips are no lower than anything else on the car.

By the way, those of you who are looking for that "best" sound, definately consider REMUS. I can get a Remus muffler or exhaust system for any of you for an excellent price.

Yes, and Flowmaster has resonators available to 'eliminate' droning. Like others already mentioned, Flows are the best bar none!
