I love questions like this!
Cargraphic Pros:
Cargraphic Pros:
- Great value vs. the marketplace
- Available in a week from Germany
- Bolts to the stock resonator if you order it with the mid-pipes
- I should easily be able to find/fit my own cats into the mids using V-bands
- I'd be buying from a site sponsor
- Not a true long-tube header (the 4-1 collector is located before the final bend)
- Untested

Yep. After a ton of research and quite a few email/phone conversations I've placed my order.
Only one set of headers/mids really fit my requirements in the end. I'll be installing, dynoing and tracking (1/4 mile) the catless MHP Long Tubes & Mid-Pipes on my car in 3-4 weeks along with an updated Kleemann K2 file.
I'll also be using a set of swappable cats (500 cpi ) for my daily commute. I'm hoping it adds enough restriction to keeps things civil during cold starts. I love the fact it should only take 10-mins to swap out for track days.
Fun times ahead!

Finally, someone who looks at the facts and makes the decision based upon research and real world testing and results. Not on feelings or what they hope they will get. It will be great having another racer out there running 11's!!
I look forward to meeting up and possibly racing with you sometime.

I've made four 12.0XX passes in the summer heat/humidity. The 12.028 was sooooo close.
These headers will help be get the mid-11's I'm looking for.
It would be great to meet up, Keith. I'm in S. Florida often and would love to check out the "Little C" in person at PBIR.

Hey now, I can run 11's without the headers now . . . I just need some cooler air.

Mid 11's will be fine until you realize H&C's will get high 10's in good air.
Then you'll be on the hunt for the next level of performance. Great to have you on board!! Once again, CONGRATS!!!!!

Congrats. I was hoping you were going somewhere with the catless DP project. Will wait for the usual detailed writeup and looking forward to your AFR results on K2 tune.

It is safe to say that the the 2.5" catless downpipes are good for +2 MPH in the 1/4 mile and a really aggressive exhaust tone. I want more.

I'm still going to finish the final tweaks to the downpipes. A couple people have already PM'd me about wanting them for their car. I will offer them up for sale along when finished. I'll also be separately selling the PLM manifolds and GT PRO X-Pipe.

I looked through the thread were there any pre/post dynos done? Also do you think you would have any noticeable gains if they were 2.75" or 3" DPs? Also where is the best location for a single set of HF cats more proximal or distal to the headers?

No gains on the dyno however conditions weren't ideal during the "after" session. I did pickup 2MPH in the 1/4 mile on the top end. Any additional testing will need to be done elsewhere as I'm moving on to Long Tube headers.

Loud but not very refined. I wouldn't want to be my neighbor when these were installed.
Installing $9 in commonly found auto parts is far simpler, less time consuming and a better value than getting a reflash to turn off rear O2 sensors.
