Well I finished this up a few hours ago. Lets start with the basics.
QTP 1 3/4' primaries with HVMC collectors

Kooks y-pipe

Spohn solid motor mounts

I didn't take pics of the engine bay with the exhaust manifolds and stock y-pipe off the car. When I replaced the motor mounts, I didn't remove anything besides the stock mounts.

The only thing I took off to install the headers was the oil filter. I also had to jack up the engine a bit to slide the drivers side header in. Passenger side header went in easy.

I used Bosch 13111 for the front 02 sensors. The wires are plenty long enough.

Now for the good stufff. The modified kooks y-pipe.

When I first got the y-pipe, I had the ends expanded so they could slip over the header collectors. The exhaust shop that did this for me was 25 minutes away. This came into consideration when it came to modifying the y-pipe. This is what I had to do. On the drivers side I first cut off the part was expanded then I cut off roughly 4 inches. On the drivers side the y-pipe had to move over to the passenger side roughly 2 inches and 2 inches to the front to meet up with the hanger. So once again, I cut off the piece that was expanded and then I cut the rest of the pipe off roughly 1 1/2 in front of the 02 bung. To compensate for having to moving it over 2 inches, the piece I just cut off got lined up, marked off, and cut at an angle at both ends. I brought the y-pipe to a race car chassis chop to weld the pieces up and picked it up today.
Finished product



I also had to do a little trimming to the I pipe that came with the Magnaflow catback.
I don't have any banging issues. Engine doesn't rock at all. Also, I don't have any vibrations inside the car. It feels a lot more solid now.

 

what are the motor mounts like? what did they replace? any vibrations, SES lights, etc? more info please awesome work man

 

i love it more info, your explanation on what you did isnt very clear.

 

looks nice man how do you like the solid motor mounts?

 

the spohn solid motor mounts replaced the stockers. i don't have any vibrations inside the car. no SES light. i had the rear 02's deleted a while ago.

 

nice man NICE

 

Looks good i am looking into QTP headers myself. Might have to jump on that sale they are having.

 

Looks like this Kooks Pipe is a good option for those with QTP headers looking for high clearance. Is your car lowered, I think I may have missed if you said that or not..

 

good stuff man.... nice info

 

stock ride height

 

very nice job man clean *** car too (underside) and i love them polished headers..

 

nice install man i hope mine comes out like that i am just worried about the Y pipe i bought the collector has a 4" outlet and then a reducer but is saposta be the best flowing, should be for 360 dollars.

 

nice install!

 

those headers are not going to be so shiney after couple days... so polishing them was kinda a waste.. but congrats i have same set up

 

Looks real good . wish my qtp y pipe tucked up that nice. How does she sound ?

 

I'm looking to replace my QTP dual cut out Y pipe. It is not clearing worth a ****. Due to a chassis mnt TQ arm thats on there. Between that and the drive shaft, the 4" collector is hitting the ds.
My car is lowered also. It keeps breaking the motors for the cut out. So I want to go back to a single one in the I pipe.

I was wondering how the kooks Y pipe fit.

Is it crushed down on the drivers side?

 

That looks awesome.

The driver side of the y-pipe looks like it could stand to be another 3/4" or so closer to the floor. With even poly mounts, much less solids, you can run the exhaust really close to the floor without it banging.

 

Kooks makes a 3" to 4" ORY. You can put a cutout in the 4" part before reducing to 3" and have nearly as much flow as dual 3" cutouts. See link in sig.

 

they came polished

 

thank you. i'm gonna tweak with the drivers side tomorrow
