2.5" and keeping the cats

thank you!

 

I left a message with him. I know he cut his shop back to part time so I wanted to make sure he wants to take on the job. If so, I'll PM you his phone number.

He said he is very interested in doing another one.

thats a sick setup

 

So I made some changes.

First I changed the tips out to 4" (were 3.5"). I think they look better now.

Also, I cut out the spare tire well and plated it up with steel. Now it is just the depth of my amps. The evap box, fuel surge tank and bosch 044 pump are back under the car.

 

Don't know if it's been already mentioned in the other pages but that is not an X pipe and the pipes don't merge inside. And it's not resonated. It's a muffler. Twin turbo setup flows individually since one turbo spools more than the other at different RPMs.

 

The manifolds for the Greddy are the same on each side and the firing order goes from side to side so the turbos should spool very close to the same. Not exact but close.

 

So both turbos both have the same specifications? I would think they would make one bigger than the other for low and high RPMs to reduce turbo lag.

 

it has one off each side of the engine. you could do a dual setup like you are talking about but that would be a much more difficult fit for the piping.

 

I reviewed the entire thread and I don't see a model number or anything indicating it is or it's not. Alot of the Magnaflow 2 in/out mufflers have a resonated X pipe inside even though the description on their site doesn't mention it.

But TTrank would be the one to clarify though. If he has a model number, I can research it.

Here is a drawing of one one I have in the 2.25" size: As you can see, it's both a X and it's resonated.

 

I belive the one I have is this one:

Yes, both are mitsu 18G's.


None of the twin kits for the VQ have different turbos. That's more common for inline motors.

Yep, you have the X inside and it's resonated. You probably didn't need it but no biggie.

 

Having a small / large turbo would put unequal loads on each side of the motor. I can't see that being ideal or even good for the motor.

Even in inline setups where this is possible, I haven't seen any aftermarket company offer a small/large combo as offered in OEM applications like the Supra or FD RX7.

 

Or BMW 1/3/535

You are right, those all use one smaller turbo to spool the other larger one. With twin scroll turbo technology getting better and better I think this is more the route people will take.

As for the larger muffler. My plan was to keep it as quiet as possible so we went this route with that larger one and two large rear ones.

I'm thinking about having Kevin make me two pipes to fit in place of that muffler so I can switch it around.
