Flowmasters on otherwise stock exhaust

[k12]

Hey All,

My exhaust finally gave up the ghost (cracked intermediary pipe on pass. side). Ive wanted flowmasters (50 series 3 chamber delta flows) forever, but didnt want to do a whole cat. back as I was staying 2 1/4 and my tail pipes are fine (read here I'm cheap).

The thing is, the flows are 23 inches overall length, and the stock ones are 18 inches. I need to lose 5 inches somewhere.

Anyone done this before and can provide some insight? Oh, I'll be doing this tonight after work.

Thanks,

Kieran

Save your money and go with an all stainless cat back later on, I wish I had. The flowmasters sound good until they rust and the baffles break out of them. Just go cheap for now and upgrade later.

I had flowmasters on my first Mustang. Then I found Dynomax. I never went back to Flowmasters. I believe the 40 series flowmasters fit better than the 50 series.

Never again. I tried to save a few bucks but what a PITA. I should have put up the few extra bucks and just got a cat back system. The measuring, cutting, adjusting, etc. is a big waste of time. The problem is the 50 series flowmasters are 5 inches longer than stock. Also, I dont have a lift or a pit, and I can't for the life of me get the damn tail pipes out from over the axle to cut them down a few inches. I will have to buy a sawsall and try and cut them from under the vehicle (supported by jackstands).

Rant over.

Yes, I would have told you that.
If the mufflers are rusted, you can rest assure the rest is shot or ready to go.
Just pony up for a new catback. I had a dynomax 2 1/4" on, and it lasted as long as the SS stock stuff. 7 years.
I have the Flowmaster 2 1/2" catback on ( see my sig), and even though the pipes aren't polish, it looks fine. the 2 1/2" flowed so much better. Check out summit racing for a good price and shipping.
