OH MY GOD. 1st thing i need to say is it is not finshed. Way too loud. I am talking unmuffled territory! So i will go back tomorrow to install resonators.

But same thing as the y-pipe, great craftsmanship. We used 2.5 inch piping from header back. And the only thing restricting airflow were the two hi-flow cats.

Take a look at the photos. Honest to God, it sounds like JGTC car. If i had another daily driver I would leave it, but its too loud for everyday cruising.

Looks good. Did you dyno it?

 

Nope. I already knew the header-back to cats were giving me about 6whp. All i did was convert my y-pipe into a true dual. I can not imagine that this doesnt add more hp. I will dyno it eventually but it was more prep for twin turbo next yr. Since now i have combined 5" for the turbos to breath.

I am sure the resonators will cut down some power. But I will remove those with turbo.

 

what mufflers are those?

 

does it have any crossover, I cant see one in the pics?

 

To Moroccan_Mole: They are Bosal. I am adding either 14" or 18" Magnaflow resonators asap.

To 2003z: There is NO cross over. I am thinking about adding an H Pipe to smooth it out. What would you do?

 

Well, I'm not an exhaust engineer, but I'm pretty sure that all the others use them to equalize pressure (h-pipe, like borla), and to help suck the air out (x-pipe, like stillen). Not sure what else it does, but seems like it would be something to consider adding

 

Here is a photo of Injen's. They dont use any cross overs. I am going to add resonators first and see how it goes. I guess my dual exhaust was inspired by Injen. I tried to pull a fast one cuz I saw they used resonators so i opted to try it without.

Lesson learned. Or should i say heard!

 

freaky resemblence aside from the resonators Injen used.

 

Looks well done. Congrats.

 

Looks great! Those are the tips Injen should have used!!!!!!!!!!!

 

How much?

 

if injen used these tips i would have bought it. still waiting for greddy

 

It would be interesting to know dyno results.

In theory there is a chance that it'll slow you down. Hot gases will expand too much in big diameter pipe and cool down and slow down "clogging" the exhaust. Those damn physics can do nasty things to our cars

 

Sweet looking exhaust/cannons!

I'd love to hear a sound clip.

 

So Matt............, it shoots watermelons right?
