4" 951 "BIG FLOW" LINDSEY EXHAUST



Similar to our Standard 4" exhaust we have been offering for years, but we incorporated the same "Big Flow" components and features as our 5" system. We grow from 3" to 4" without the 3.5" transition. But what makes this 4" and our 5" "Big Flow" systems unique is where the tie or connect the wastegate back into the primary exhaust system. We do it where the pipe is 4" in diameter, and we do it "after" the optional pre-muffler or catalytic converter. By doing this, we are not re-introducing the exhaust from the wastegate back into a 3" pipe, pre-muffler or a catalytic converter which increases the overall back pressure. Thus the "Big Flow" name. That makes this the best flowing, least back pressure 4" exhaust system on the market with our without a catalytic converter in place.

NOTE / WARNING: What ever exhaust goes through the wastegate, does NOT go through the catalytic converter so it is not scrubbing it for emissions. This is typically under WOT and/or high boost conditions.

This exhaust is made from aluminized coated steel exhaust tubing and grows along it's length from 3", to 4" in diameter. Formed with mandrel bends making it free flowing throughout without pinch points and collapsed tubing like the factory system. All tubes are CNC mandrill bent.

All systems come complete with copper gasket and band clamps. Nothing else is needed for installation.

OPTIONAL 3" TURBO DOWN PIPE:


If you have been considering topping off your exhaust system purchase by adding our 3" Turbo Down Pipe, this is the perfect time. When you select the Turbo Down Pipe option now, we substitute the normal 3 bolt stock bolt circle triangular flange connection on what we refer to as the "wastegate pipe" for the larger diameter 3" Bolt Flanged pipe that mates to our 3" Turbo Down Pipe.


OPTIONAL CAT DELETE, CAT AND PRE-MUFFLER:


The second pipe in this system is where you may place a cat delete, catalytic converter, or a pre-muffler. This is offered 6 different ways because in each of those three options, you have the choice of connecting the wastage back in, or dumping it to atmosphere. This gives us the 6 possible options.

  • Cat Delete Pipe w/o wastegate connection (dumping wastegate to atmosphere)
  • Cat Delete Pipe w/wastegate tied back in connection
  • Pre-Muffler w/o wastegate connection (dumping wastegate to atmosphere)
  • pre-Muffler w/wastegate tied back in connection
  • 300 Cell High Flow Metal Cat w/o wastegate connection (dumping wastegate to atmosphere)
  • 300 Cell High Flow Metal Cat w/wastegate tied back in connection

100 Cell Higher Flow Metal Cat's are available upon special order.

MUFFLERS AND MRP'S:


The systems do not come standard with a muffler or MRP (Muffler Replacement Pipe) included in the system base price. It's an option you select and purchase separately. Some of you may already have a muffler you want to use so we don't force you to purchase one from us. The dimensions of the 4" mufflers we use are 20.5" overall length, 4" center in, and 4" center out.

  • Magnaflow 4" Stainless Steel
  • Borla 4" Stainless Steel
  • Muffler Replacement Pipe (MRP) - 19" Hollow pipe replaces muffler. Loud!!

TIPS:


The standard 4" exhaust comes with an slash cut outlet pipe from the muffler which serves as the exhaust tip. We have configured this outlet pipe a few ways.

  • Standard 4" Slash Cut Outlet Pipe
  • (Optional) SS Polished 4" Slash Cut Outlet Pipe

THERMAL COATING:


If you wish to have the exhaust thermal barrier coated, that adds $200 to the price of a system. Highly recommended for a track car. It will help keep the heat from entering the driver compartment. The thermal coating also aids in keeping up the velocity of the exiting exhaust by helping maintain the heat in the pipe rather than letting it cool down as quickly and slow down. It will also add to the life expectancy of the exhaust. With or without the thermal coating, the exhaust will give you many years of use.

(Optional) 02 SENSOR BUNG & PLUG:


If you plan on using a Wide Band Oxygen Sensor, we can WELD the bung on the exhaust pipe for you before shipping your system. The additional charge is for the Threaded Bung & Plug Kit and the labor to install ( WELD ) the bung to the pipe punching the hole through the pipe. You can select this option when ordering your exhaust.

(Optional) WASTEGATE OUTLET DUMP TO ATMOSPHERE MUFFLER:


Any of our 944 Turbo exhausts have the option to dump the wastegate to atmosphere. When you select that choice for your system, you get a Wastegate Outlet Dump Pipe or turn down as standard equipment supplied with the exhaust kit. The sound coming out of that can be loud since it's pre-turbo. So we developed a Wastegate Outlet Muffler. You can select this optional Wastegate Muffler through the exhaust checkout process. We will supply this outlet muffler, and you will not get the standard turn down.
