Just got exhaust, cai, unichip, flux display and headers.

Just found a killer deal on CL... I got urd 3" Mk2 exhaust, Doug thorley long tube headers, unichip programmer with flux2 display and trd cai for 850.00. I'm pretty stoked and want to hear what you guys here think? Good and bad. Lol. I'm having it all installed tomorrow. I'm probably gonna put some on tonight. Hoping this setup will help out my truck since I've lifted it and added the weight of allpro's bumpers and expo leaf packs.

 

Damn sweat deal!! That pretty close to my setup. Gibson exhaust, dtlt, urd maf cal and Afe stage 2(same as trd). You'll be stoked!! Nice powers gains all the way through.

 

Let us know how you like it when you get it installed! Sounds like a good deal

 

That is a damn good deal on those parts. Post up some sound clips once you have it all done.

 

Ok, thanks guys. Not really looking to be faster just maybe a bit more low end and cool sound.lol. Already after I installed the trd cai it sounds better! Now at auto shop waiting for the rest of my performance package to be installed professionally. I have a really good auto mechanic. Can't wait! Hopefully everything works and goes on smooth bc after al it is a CL deal.

 

Loving it!! sounds good to me. Just URD Y-pipe now gonna put that in and get back to ya... hopefully not too loud then.

 

Based on what I learned today, opening up your exhaust you'll actually lose low end. But like I said, it's new knowledge, but it came from someone with old knowledge.

 

Hp gains mean faster...you don't see NASCAR running stock camry's and impalas.

 

I think what he's trying to say is we should all get a NASCAR motor and stop wasting our money on petty things like mufflers and strippers.

 

Memario
That is correct. In the instance of these trucks the lack of back pressure created by exhaust mods leads to a decrease in power in the lower part of the RPM band. It essentially moves your power curve a little bit later in the RPM range and the mods give it a little higher peak.


I think by back pressure you mean scavenging. I've heard lots of people get scolded by chris4x4 for that one. Only reason I know.

 

Not necessarily. That statement is to broad. On these trucks, you still have to keep things realistic, as in don't put a 4" catback on, or headers with 2 1/4" primaries.

However, cleaning up the exhaust, such as replacing components that have kink or crush bends, with those which have mandrel bends and better routing, will increase power across the whole range. Some areas more than others.

Depending on which combination of exhaust components, you can watch the powerband shift this way or that, a little. However, for the most part, the combination of components sold by URD do a good job of increasing all of the useable powerband.

 

Here is a good thread, for those that haven't seen it.

If more people dyno'd, we would have more results to increase accuracy.

 

Strippers and Mufflers are never a waste of money, now NASCAR on the other hand...

 

Unless is Rickey Bobby and Cal....Shake and Bake!

 

so how does the 3" exhaust sound on these trucks?

 

with headers, 3'' exhaust, urd y-pipe and trd cai... It is loud as hell. I really like it. even in higher rpms when it sounds raspy its like a race motor sound like in ken blocks gymkhanna videos when he's redlining in the begining. cant wait to get the right map in so I can really feel the high end power. Yes I have lost some low end but honestly I did it for sound and got a great deal on it all so its worth it to me plus lifted taco on 34'' not made to go fast.

 

Great deal. I hope you don't get tired of the sound.
