Good catch...I was just mocking up parts and wanted to see if the dimensions on the LS7 TB are the same...its going in the car after i fix a couple of issues and get it ready for the tune.

 

Yeah, it's 4" on both ends, and with a little heat gun lovin', it went over the stock airbox lid easily. Kinda like a fat chick puttin' on spandex.

 

Thats ALOT of heat!

 

You can buy aluminum bends and strait 4" by the foot from Columbia river mandrel bending. Then fit your pipes together mark em with a sharpie and your golden.. I ya bought one 4" 90* you could probly use what ya got if you cut to fit just right.

 

X2 for silicone intakes dot com .

You need a 4" 45 bend with 4-6" of straight pipe on each side that you can cut where needed , you can also use the ZR1 piece you have also for the MAF bracket , then get a silicone 45 elbow to go from throttle body to pipe , then either another 45 or just a hump adapter to tie the air box in . Also get some of the nice looking T bolt clamps for a pro looking job

I'm not pimping my intake , just posting this for an idea of how I did mine ( mine is 4.5 " though , I reduced off the TB )

 

T-bolt showoff!! Why you always gotta one-up me Tim?!?

Haha, jfwy buddy. Your truck is a bad bitch.

 

 

Tim, Pat, where you guys getting those heat shields? making your own?

I like my stock box, but im not opposed to getting rid of it

 

My filter and shield are AirAid.

 

Your my hero Roger , but I have hardly anything to show off , especially with you and Pat posting pics here


Smokey , my heat shield is from the original K+N kit I had , and the air filter is a big beeyatch from AFE, it's a dry flow and the same one I ran on my dmax .
