Fast Intentions Gen-1 to Gen-2 midpipe swap. All i have to say is WOW

So i purchased my FI catback about 6 months after buying my G back in 2009. since then, ive put close to 80,000 miles on it and it still sounds great. the only problem is the magnaflow midpipe that is used as the Xpipe/Resonator combo seemed to be getting more drone than it did when i first installed the system. After talking to Tony, it sounds like the packing inside the Magnaflow X was more than likely blown out, and thats what was causing the drone. Id attribute that to the HFC I had installed, as they dont retain as much heat as the stockers, and id assume the extra heat being that close to the cats was what contributed to the failure.

He reccomended i purchase a Gen 2 midpipe. the Gen 2 is what comes on all the new systems they ship, and its 100% backwards compatable. I opted for the 18" resonators to reduce drone as much as possible. its got a true X, not a muffler and it definately shows in the sound department.

The new Midpipe. came very well packaged and in perfect condition. leadtime was 4 weeks on the dot.

This is the old midsection before they took it off.

And After.


My initial impressions on the sound difference. its WAY Throatier/bubblier. Drone is way down under cruising. it just plain sounds amazing. as far as the butt dyno goes, It feels quicker, but thats purely objective. its supposed to make more power over the original Midpipe, but not enough for any normal person to notice.

If you're itching to upgrade something, id say its worth it if you have one of the older systems like me.

it replaces the old section of the Fast intentions catback. this wont fit on a stock exhaust system. you have to have the fast intentions catback to order the new midpipe.

of course you can always pick up a full catback from them, and it comes with this midpipe. i believe they run around $1,100 plus shipping.
