    I'm looking into LCE pro flow kit with the 2.5" piping and magnaflow muffler for the 2nd gen 4.0l (getting one in the near future :)). And their catback is def the cheapest i can find at 400 bucks but it still seems like it would be cheaper to get just the muffler from them for 90 bucks and then get an exhaust shop to fab up the 2.5" catback. So my question is to all of you that have 2.5" piping that was custom done, how much was it? Also, did they have to use some sort of adapter to pair the new piping with the 2.25" y pipe?

    Or would it just be best to get a 2.25" in and 2.5" out? since then that would def be cheaper and no worries about pairing it with the cat

    I had a complete custom exhaust run from the catback. They ran all new 2.5 in piping after the cat all the way to the tail. I'm running an AeroTurbine with stainless tips. I pretty much just bought all the parts to them and they supplied the piping and did the install. If I remember the cost was about just under $200 for 2.5 in piping, adapter, hangars, and installed. The tips and the AT muffler cost me around $185 purchased online. Couldn't be happier...

    Perfect thanks man. thats exactly what i'm looking to do, so it would be slightly cheaper since the muffler is $90 and a $50 tip along with the price of piping and install

    I would advise against that large. Too much backpressure loss to gain anything in the low end. I would say Yes if your planning to keep rpms high all the time.

    2.5 is the most I'd go remember our trucks aren't pushing large HP numbers so 2.5 frees up just enough room to help the exhaust gases exit more so than stock, but not so much that it affects the backpressure in the system.

    4 cylinder or V6?

    What kind of gains? Ya you can get some awesome gains in a part of your power band you are never going to drive in...

    I have Doug Thorley header and the Jardine 2.25" cat-back exhaust and have tried to get rid of it. I do not like it compared to when I was just running the header. I felt a huge improvement over stock with the header which all got dissipated by my seat of the pants feel after installing the cat-back. I felt like my low end did not start until much higher in the RPM band. Thats just my personal experience with it.

    are you saying you have a 2.5" CB? b/c 2.25" is the stock size anyways. I'm talking V6 and LCE has the pro flow kit for the 4 cyl at the same stock size of 2.25" prob for exactly that reason ur stating

    Ya sorry, I thought you had a 4 banger cause thats what it says under your avatar. If you have a v6 then I say 2.5" would be perfect.

    Back pressure is bad, regardless of size. Stock exhaust systems are engineered to have almost no back pressue. "Back pressure" would = restriction, and kill the volumetric efficency of the engine. Now....When dealing with exhaust systems, Scavenging is what you dont want to fuck with. Unless you time the engine accordingly. Read this:

    CHRIS I thought some backpressure was needed for when valve overlap on the intake stroke happens..

    well i figure there has to be something to the stock size for toyota to make it that way. Just gonna throw on a 14 inch magnaflow like the one on my 4 banger and have a tip welded on (maybe piping position/hangers changed a little bit for aesthetics). Honestly with the intake and magnaflow muffler, my 4 banger sounds pretty good and surprisingly deep. So i figure it will sound even better with the larger engine of the 4.0. Just no intake this time, waste of money for sound when i can get the same performance for 1/6 of the price with a pro dry s drop in and sec. filter removal...
