I heard the magnaflow had a great exhaust for these trucks? I just did some research on their system and for $616 I might have to pass...

i didnt do the full Magnaflow cat back... i did however install a 24" (or maybe 22" inch but i thought it was 24") muffler and the truck is really pretty quiet for being a straight through design IMO... I forget exactly, but i think i paid like $80 or $90 for the muffler shipped and another $45 to get it welded up, not a bad price if you ask me.

I was going to wait on the cats till i did my LT's, and even still i am not sure what i will end up doing there... need to do more research

I have the same, true duals with 22 or 24 FlowPro and it's only loud if I get on it..they are old and have some drone, wouldnt be surprised if they were spot welded

Changing mine out for Magnaflows

tybardy,

Sounds good...Might need to just check into a muffler then before I get a full Cat system.
Anybody installed headers on their truck yet? IF so how much time and effort were needed?

Tybardy,

Are you dumping it right out of the muffler? It did seem pretty quiet except at the higher RPMs. Does it pop when you rev it up?

I like it but I don't want popping. I wonder if a tailpipe would help eliminate it.

Also, have you noticed any mpg gains from your mods (BB Tune, Intake, Exhaust)?

Love the rims man.

thanks thanks...

Yes i have a turn down directly after the muffler.

it only pops when i rev it up like crazy in neutral... when i have my foot on the floor driving it doesnt do it at all (maybe a small amount when i am at extra high RPM and take my foot completly off the gas).

As for the MPG's I am getting about 19 average right now. Thats at about 60% highway driving and 40% street. That also includes me NOT driving crazy ever. dropping the hammer is no good for the milage. Also note that i have a 91 octane tune, so my 19 is probably the same cost as an 87 octane 16 or 17 mpgs. when i pulled this truck off the lot is was averaging only 13.8 mpgs

The intake gave me a big jump in milage and the bb tune gave me another big jump in milage. I recomend both, the muffler was more for sound then performance but i wanted to make sure i had it prior to getting my tune so Justin had it all on the table to work with.

Wow. I'd be pumped to go from 13 to 19 when driving the same streets (hwy/city).

You mentioned the pop sound after letting off the gas (in high RPMs)....I wonder if that is a magnaflow thing.

I had a 99 cobra that had magnapacks on it. I changed them out for the magnaflows and they did the same thing....kinda like a backfire but not as pronounced.
