I want to get some headers and exaust, and I would like some advice on the most cost effective/ease of install option.
I have my eye on some TRD headers as well as the cat back because of the seemingly direct bolt on, but they are pricey...
I've also been looking at borla for a cat back, but for headers, what other brands are there that would offer a relativly headache free installation.
-Thanks

trd headers are way to expensive. go to downey or jba. URD has a 4runner with 270 hp with stock headers. save your money for other things. just my opinion.

 

[firemantodd]

i do like the borla exhaust tone. complements the s/c whine nicley.

If you have the v6, don't bother with headers until you have the superchager. The price per pony pales in comparison. The TRD headers are nice, but install is a pain and most people will recomend you take it to a pro. Between my TRD headers and cat-back installed by the dealer, I easily could have purchased the supercharger and installed it myself. Live and learn. I think Edlebrok makes headers for the v6, but the crossover pipe is routed underneath the tranny and can be a liability on the trail. If your mind is set on headers, I think that even Gadget recomends sticking with TRD both for fit and performance.

Headers and exhaust

Have the TRD headers and cat-back. Very expensive to start. Check with dealer on installation, which is also very expensive. Unless you have a lift and 8-10 hours of time, do not attempt to install yourself. My personal opinion is if you are not supercharged you do not need headers. Stay with the cat-back exhaust and put the header money in the bank and save for S/C.

thanks for all the responses...
That's the advice I was looking for, I think I will just stick with the stock Exaust manifold untill I can supercharge.
As for the cat back, which would everybody recommend?

 

[Breathegood]

That depends. Are you looking for bling, performance, or noise? TRD is nice for bling factor, and I like the low mello sound mine makes (keep in mind I also have headers), but I'd really like to do a post axle dump and I can't bring myself to cutting off that beautiful stainless TRD billet tailpipe. If you're looking to save a few bucks and make some noise, just use stock piping and replace the muffler with a Magnaflow or Flowmaster. If performance is what you want Gibson, Jardin, and Borla make nice cat-backs, but you may be dissapointed with the performance gains you get. I probably missed a few, but there are some options. I think there is a thread in the "Performance" section with sound clips from several different setups.

With my engineering mindset, all I want is performance unless it makes me sound like a farting hippo

Read my post under "Magnaflow Help". You can have that catback put on your truck for a lot less dough and it will still be the "right" one after you supercharge. It's not shiney or stainless but it sounds good and flows well.

I agree with the others about waiting on the headers until you are ready to put the S/C on. I did gain in the upper rpm ranges and got better gas mileage but not enough to cover the expense and genuine pian in the butt installing them. After the S/C---that's a different story.

Dave, do you have any sound clips of your exhaust?

No, I'm sorry I don't. I am sort of "computer handicapped" and wouldn't know how to post it even if I had one.

Didnt alot of people have problems with aftermarket (including TRD) headers cracking? Also are there any exhausts out there that are made completely from stainless (304 or whatever the best is) and offer a lifetime warranty? I would like to just do the magnaflow but I have had so many custom muffler shop exhausts that only last 2 years in these harsh Ohio winters

TRD headers used to crack but since they changed the design, I haven't heard of any cracking problems. Don't know about the all stainless exhaust. I bet an all stainless would be pretty spendy though.

Thanks for the info,
I see you have an airaid MIT, how did that work out for you? Is it worth the time and money?

I like the MIT. The time to install was only 5 minutes. Is it worth the money? It was to me because I wanted to "clean up" the intake tract both in appearance and smoothness in flow.

Had a similar conversation on another site. It seems to me that a less restrictive muffler is all you would need (primarily for a better exhaust note) unless you have a S/C. Once a S/C is installed, I would think that along with the headers and cat-back you'ld need (want) to replace the cat(s) with higher flowing units as well. The OEM cats pipe down to about 2", maybe even less(?).
My opinion. Not based on fact or experience. No lifeguard on duty....etc.

 

[Mikevr007]

I would love to see some dyno numbers comparing stock vs muffler vs headers vs headers+catback vs headers+catback+cats.

Somone get on that, asap...
