Crossover/mid pipe Recommendation

[Toyota John]

I am looking to get some recommendation for a catless crossover/mid pipe in combo with my EL catless header i have. I am looking to get the quietest best flowing exhaust combo I can find. I have an Agency catless header, Agency mid pipe and greddy evo 3 exhaust and its way to loud. I was hoping to keep the greddy cat back and replace the crossover mid pipe to keep the noise down but if i have to replace both I will.

"Catless" and "quiet" are mutually exclusive.

If you want a quieter exhaust, get a front pipe that has a high flow cat and a resonator. Nameless makes one, Magnaflow makes one, there are a few more that I can't think of at the moment. Then get a quiet cat back with a resonator such as the resonated Perrin or the Invidia Q300.

sounds like you have stock front pipe and over pipe? if thats the case i dont think you can get any quieter than the stock pipes.

if you want less volume get a catted front pipe and change the cat back to something quieter. A single muffler CBE is usually the way to go for quieter.

my vote is nameless combo pipe but you have to jack the engine to get it in.

Maybe I am calling the parts by the wrong namw. I have a full exhaust. Agency EL header, Agency crossover and forward pipe that connects to the Greddy evo 3 cat back. I put the stock catback back on for now because it was way to loud. I was thinking the Greddy SP because I like the tips and people are complaining its too quite but I don't like how is uses the stock rear cat back pipe with the sp muffer. But the Crossover and front pipe have so many different companies making them, I don't know where to start. If anyone is running a catless header, what is the rest of the exhaust parts you are using and a youtube clip would be nice too.

The crossover pipe is just an overpipe, and the forward pipe is the front pipe. The front pipe has a cat and a resonator; the overpipe is just a pipe.

So you're basically running a straight front pipe, with no cat or resonator. I'm not familiar with the catback you have, but I'm guessing it doesn't have a resonator either. Which means that the only thing quieting the exhaust is the muffler, which is not up to the task.

If you want to run catless, try to find a front pipe that has a resonator in it. That'll help a little to calm things down. Two of the quietest aftermarket exhausts are the Perrin resonated and the Invidia Q300, which is also resonated. One of those and a resonated front pipe will make a difference. Having a catted and resonated front pipe will make more of a difference. The cat will help smooth out the rasp that you get from a UEL header that is running catless.

If you want to go even quieter, get a catted header, catted and resonated front pipe, and one of the exhausts I just mentioned.

This thread has a lot of youtube videos of different exhaust configurations.

Nameless dp/op is your best option IMO.

Both my Agency front pipe and cat back exhaust have a resonator. Here is a sound clip. [ame]http://youtu.be/SaQsnxkGrWA[/ame]

It sounds like a plane.
