Exhaust or No?

I have the 4.0L with k&n cold air intake. wondering if i should put exhaust on or not? and also what brand. any advice would be helpful.

 

Dunno...but just looking at the main page there are like 4 other posts about exhaust...try them out

 

Do it! I'd get the TRD Catback and will hopefully soon for my truck.

 

+ 50hp???

 

No.... unless that 500 bucks is burning a hole in your pocket... in which case you could just paypal it to me

 

Exhaust do help out alott.

 

That

 

cherry bomb dat faka!

 

Just cut in a new muffler if you want a bit more sound, price is much better than a catback. Performance-wise ain't going to be much, if any, difference.

 

I'd like to find a more efficient exhaust than stock for my 2011, but with a volume in between stock and fartcan rice grinder. The quieter the better.

I had a 98 Tacoma with the 3.4 V6. I put on the TRD headers and supercharger. Oh what a feeling!

Next, I put on the TRD cat back. It MUCH louder than the stock exhaust, but my gas mileage, especially highway mileage, improved quite a bit.

After a few months, I took the cat back off and sold it.

If I was 18-21 yo, I would have loved it! But, as an old guy, it was just too loud for me and for my neighbors. My schedule had me leaving home really early (4 am) and the truck's exhaust was pissing off neighbor's trying to sleep. I also felt bad passing people, since the exhaust was right in their ear when I went by.

 

If a muffler only does the same as a cat-back after market
why the heck do most go for the after market at 4x the price?

 

Loving the Magna Flow off road exhaust on mine. Sounds great, but not over the top.

 

Cuz they are being marketted to! Also, a catback can be done in your driveway yourself, a muffler will predominately need to be taken to an exhaust shop to weld in.

Think about it and look at the piping on the catbacks. Stock is 2.25" piping that is reasonably cleanly bent already. Catbacks will increase the size to 2.5, or some use 3" (Banks). The 2.25 to 2.5" piping, might help a bit at high rpms, but that's it. The 3" will cool and slow down the exhaust gas velocity quite a bit, that will affect the low rpm power as less scavenging will occur, i.e trading low rpm breathing for high rpm breathing. Again worth a few HP at high rpms, but can cost some for daily driving.

If you do a bit of searching you will see that the vast majority of NA Tacoma modders don't feel/measure much of any performance increase from a catback. Sound only. Those that "feel" an increase have no measurements to back it up. Given this, it's cheaper to cut in a new muffler for the sound, unless you want every last bit of high rpm breathing you can get. Even then, if you're NA, chances are it's not enough to even measure (dyno or track times).

 

good post and prety much what I've seen as well. I thought other than
the muffler we've got a decent setup already so I was planning on just
a muffler replacement. No way to cut & clamp a new one on?

 

Borla.

 

After driving vehicles with loud aftermarket exhaust for many years, I love the quietness of my stock exhaust. Plus, it's a truck not a racecar, who gives a shit about horsepower?

 

i do

 

Exhaust alone will not generate that much horsepower to make a giant difference would it? Other mods would be needed to see significant increases horsepower right?

 

Cat backs will get you somewhere in the range of 5-10. I understand headers will get something more substantial, but it comes back to the point that the only way to get noticeable power out of these motors is a blower. Until you do that, all you are gonna get is sound and the satisfaction that you spent a bunch of money on aftermarket stuff.

 

I do too...but not in my truck. It's a truck. It was not meant to go fast, it was meant to haul things. Trucks need low end torque not horsepower.
