MAC Prochamber Install Questions

svt_wmd · September 4th, 2009, 01:47 PM

After searching through can't really find an answer...

I'm about to order a Prochamber for my 01 cobra. It has Hooker LT's on it right now with a 3-bolt collector flange. The Prochamber has 2-bolt flanges on it.

For those of you with this issue, what did you do to make it work. The MAC tech said that most just cut off the 3-bolts, and weld on 2-bolts. Also you can remove the flanges altogether and swedge (sp?) the midpipe over the collector pipe and clamp it down. just looking for the most reliable method. If anybody has done this which option do you recommend? He also said that you have to chop the prochamber up to make it fit with LTs even buying the shorty PC which is made for LTs???

Any advice is appreciated guys

Just ordered a Borla stingers cat-back, its on the way too!

the header collector location is probably different for the slp's as it is to mac's and that is why a little more cutting may be needed. he is also saying that since the slp's have slip fit collectors that you can slip the PC in to it and fasten it. i personally would use flanges of your choice if i was to be keeping the PC.
