Santa brought me a set of Cat Delete pipes to replace my big HJS 100 cell cats on my Milltek exhaust..
Now what to do? ...lol..

 

Santa clearly wants your turbos to spool up quicker. What a thoughtful guy!

 

Thanks Santa...

 

May give you a little pep up top too. TQ will be a bump. Make sure she is still okay on fuel John.

 

Hi Sam, Thanks..
Now I have more of a reason to go towards the 3071 BECAUSE I can take full advantage of these pipes then.. Lol..

 

i think this is the only way for "santa" to be happy! LOL

 

Santa dropped me off some new wheels and tires. Didn't know he was such a car guy..

 

You have to leave German pastries for him!

 

Do they require a retune/reflash?

 

Hard to say because I am running on the edge of 93 pump gas now with my Protomotive tune And these 100 cell cats are rated from HJS at 350HP each plus if there is restriction in muffler piping it might not help ,, so I really dont know what to expect??

 

Damn.. Santa like you or likes to mess with you... John What cat delete pipe? I think the miltek is one piece and will need some fab work to fit up the cat delete pipes.

 

Tim you are right.
Milltek is a one piece system in which I will need to cut the cats off and then have a pipe made to run from the end of the cat delete pipe to the inlet of the muffler piping..
EB Werks really took care of me and made a nice set of pipes with V flanges welded on the end of them and gave me a set of weld on V flanges with clamps so that I have options......
The cat pipes are 3'' OD by 8.75'' long from one end to the other..My inner muffler piping is 2.75'' with a connector/balance pipe running between the two mufflers..

 

John,

I seem to remember that the post cat to muffler pipe is quite large on milltec's system?

 

 

Seems larger then 3''.
