Exhaust System Roundup

CATALYTIC CONVERTER SMELL

Hey Guys,
For all of you that have installed dual exhausts. Do you see (or smell) any difference in the catalytic converter smell? Thanks.

From what I can tell is that I don't have the smell anymore,but I did the TSB sulfur a week before installing the borla dual exhaust. It's still pretty cool up here in NYC so haven't got a chance to drive with the window down yet. Once I get out the truck I can still smell the oil burning from the borla exhaust and the new converter For now I love the sound and the look.:cool:
 
I noticed a change for the better after installing the MagnaFlow cat back system. 70% less smell.

i didn't really notice the smell on my factory exhaust. But I can say the major improvement from the magnaflow is the power and sound.

Did you get a new converter with your exhaust system?

Yes I just got the TSB done one week before installing the exhaust, which means the converter was change with a new one.
 
I went with a full custom Super 40 Series Flowmaster dual exhaust setup. It cost's LOTS of money for a full custom, but i think it was worth it. I'm one of those guys that love loud exhaust so i don't mind the drowning sound. Flowmaster gave me a really DEEP aggressive noise, which was what i was go'n for. I love it. My record is 15 car alarms set off in a 3 level parkade.

I can get pretty much all those exhausts, but do they all fit with Xreas and without? I don't want to add them to the site if some fit and some won't? ANyone know for sure?

On my own truck I did a customer setup, which all I really did was swap out the muffler only. It's a very aggressive sound and I've sold a few to guys with 03-06's, just the muffler. It's a louder muffler but sounds great.

Are the HP/TQ increases measurable or are we just talking sound for these aftermarket exhausts? How do they compare to each other from a HP/TQ apsect?
 
Sounds great. I"m still trying to work on getting a sound clip of my car on here. When i do, i'll post it on.

I thought the TRD sounds great but out here in AZ with the speed limit being 45 all over and whatever the RPM range is around 45-50mph I got an annoying drone. Bothered me enough to remove the TRD muffler and put the stock back on. Still sounds good when I give it some throttle. Too bad I paid $900 for some freaking pipes.
 
I've sold just about evey brand exhaust system, and Gibson is more on the quiter side. It sounds 10 times better than stock, but not 10 times as loud like some. It's very civil, and still has a nice throaty tone without being overbearing.

exhaust mods

Which system looks the most like the stock system from behind and gives the most performance? From reading this board it seems users are more focused on the sound and appearance. Even with intake mods it seems none of these really give a seat of the pants difference. Just wondering if anyone disagrees. I would like to make mods only if I can feel, not hear, a difference. I had a Gibson catback on a V8 02 Explorer with K & N filter - it sounded good but not sure I could distinguish more power. The estimates for these mods seem to be in neighborhood of 10 hp but not sure I can feel that in seat of pants.
 
I just installed my magnaflow today (390 shipped from performance peddler) Sounds great and seems to have a little more torque. I overtorqued and broke one of the clamps and found that napa sells a much better clamp that seems to seal the exhaust much better, its 3 inches wide compared to the kits 1 inch wide clamp (also has 2 bolts rather than one). Next:either k&n or valant intake

Jason,

Is the Gibson side-exit like the MagnaFlow or rear exit like the stock system?

My stock system cooks whatever is on my hitch cargo carrier. Thanks.
 
I had a Borla on a previous vehicle and liked it very much. Good sound and great fitment. I'm steering clear of it on my 04 because of the crossover. I like dual exhaust but the photos I've seen of the crossover suggest that it would compromise clearance.

I had a Gibson on a F-250 and it was OK after I installed it but installation was a bitch. Fitment poor.

Flowmaster: Seems like I read a lot of threads on the Tundra board that talked about this system being so big that it didn't provide enough backpressure. These posts all had to do with the V-8. Guys were pulling them and putting back on their OEMs.

Magnaflow: I guess this is what I'll get esp if I can get it for the ~400 bucks from performancepeddler. I sure don't like to hear about drone 1500-2200. As you all know, the V-8 hits a harmonic at 1800 and vibrates there as it is. Well, maybe a bigger final drive ratio after awhile to raise the cruise rpm a little (and get more lowend torque).

While I'm at it, I'll say that the most noticable performance enhancements I've done on trucks (in order biggest to least) are:

Raise drive ratio
Headers (w/cat back)
Larger throttle body (w K&N conical filter);

never used a chip
larger tires lose torque (of course)
throttle body risers are worthless
haven't tried different ignitions but "better" plug wires don't do anything
I actually liked Splitfires on previous vehicles but will stick w the NGK iridiums on this truck

Anyway, my two cents.

I looked into the gibson before I purchased my magnaflow but after seeing that the construction was T409 Stainless Steel and not T304, I wasnt going to bother with that.

Heres some reading for you guys on 409 vs 304. Taken from a Diesel Performance store.



What makes stainless steel

From what I hear, pretty much any exhaust system installed on the 4.0L V6 won't have as bad a drone as the 4.7L V8? Correct me if I'm wrong. I am now leaning toward the Gibson. Thanks for all the input gang.

Aloha!
