1. Begin by placing the vehicle on a lift or four jack stands at maximum height

nentsintoacompletesystemonyourgarageoor,usingthediagramprovided.

2. Remove the existing exhaust system from the headers, exhaust manifolds

back or the catalytic converter. You can also remove any hanger mounted to the

frame as your new kit includes new hangers.

3. Now, install your new components. You will be starting from the back of

the car and working your way forward. Begin by installing the new tailpipes. Your

new tailpipes will not require trimming unless installing tips.

• Side exit style: Temporarily hang the tailpipes over the rear axle. These

tailpipes utilize factory mounting holes located on the frame rails near the rear

tires. Place the rubber tailpipe grommets onto the “L” shaped hangers, slide the

bolt through the hole and thread them into the frame rails. If factory holes are not

present,newoneswillneedtobedrilled.Slidethemufersontothetailpipesplac-

ingasupportunderthem.Youwillbeclampingahangertothebackofthemufer

neck and attaching it to the under body of the car. In some applications, your factory

hangers may be used.

est to the drive shaft and the outlet should be towards the rockers of the car. The

clampattachedtothehangeratthebacksideofthemuferwillbetheonlyconnec-

tion clamp used.

5. Next, install the x-pipe or converter back Y-pipe. This is where trimming of

thefrontlegsandrearlegsmayberequiredfortheoptimumt.Installtherearleg

extensionsintothemufersrst.Yourcenter“X”shouldlandapprox8-12inches

behind the tail shaft of your transmission and centered under the driveshaft. Also,

the center plate in the “X” has an arrow stamp which must point forward. Slide the

xedrearlegsintothereadlegextensions.Lengthtrimmingwillbenecessary.

The approx amount of material to be trimmed off will be 6-9 inches depending on

transmission, cross member and header location. Next, slide the front legs into

the x-pipe. They should end somewhere close to the humps in your transmission

cross-member.Thesemayneedtobetrimmedtotthewidthofyourheadersor

optional down-pipes. Be extra careful when measuring and cutting. A helpful tip:

Line up the front legs under the center “X” to mark your cut lines making sure to line

them up with you headers or down pipes. Finish the system by connecting the front

legs of the x-pipe to the headers (collector reducers) utilizing the two 1ft connection

pipes. Trimming the length may be required. If down pipes are used, make sure

they end close to the rear side of the transmission cross member. If they are too

long they must be trimmed. Some header applications require custom collectors

due to the header not ending square and parallel in the car. For proper system

t,yourcollectorsmustrunparallelwithyourrockerpanels.
