WOW. That's all I have to say. I just got my magnaflow muffler swap done and that has to be the best mod out there. ANYONE that wants an inexpensive modification that will give you really nice sound and a very nice butt dyno result I highly suggest this. Bought the muffler for $62 and got it installed for $50. That's $112 for very noticeable gain in power and nice throaty sound.

I was going to look at a full cat-back system in a couple years but I think if anything I'll stick my money into some new cams.

Just went for another ride and yes, I can now burn the tires for about 5' from a standstill. Unreal.

Congrats! Hows the sound from inside the cab? Any resonance at highway speeds?

 

[anmut]

I get some resonance at 1600rpms when going from 22-27 mph. At 72 it's kinda loud too but I think 72 is just the sweet spot for that sound. 68 and 75 are quiet.

Also - my instant mpg looks like I get at least 3mpg more. At 30mph on cruise control and at 55mph on cruise it says 24mpg!

YUP....my Magnaflow also drones at 70-72 mph.......that and the Brute Force CAI.....good times

As far as the 24mpg.......pretty sure that aint happening...I have had the Mag and the CAI now and still only get 350 miles per tank if I baby it.....15mpg more real. But if you got some secrets your hiddin....please tell us...i would love just once to see 17 mpg....LOL

Congrats

Like I said though - that's the instant mpg meter on the truck at exactly 25mph and 55mph. At below or above it gets down to near 20. But hey, I'll take 20!

I'll have to do a little math the next time I fill up.

 

[AZPRO4X]

did you change the end of the pipe to make it look better than that curve

Here's the muffler:

http://www.hottexhaust.com/detail.asp?PRODUCT_ID=12258

Model number is 12258

To install it they cut out the old muffler and had to bend the two pipes coming off the headers (no Y pipe on the 07/08 models) in slightly right before they get to the Magnaflow. The bend is maybe 3*. No chopping pipe - with the 18" it went as a direct replacement.

Probably as far as putting it in, welding the new muffler in its place is probably the hardest part.

If you mean the final pipe in the exhaust system - no. I left it the same because it points at pedestrians and people in the right lane. Hehehe

I do want to find a tip for it though but $60-70 for a magnaflow tip is more than the muffler. There's a local guy that makes stainless tips that I might install down the road. As far as looks though I like having the sleeper truck. Looks stock on the outside until I floor it. No dumb stickers or coffee can pipes stick on the back.

 

[AZPRO4X]

thank a bunch

Kinda like the Ram I saw today with the K&N sticker on the window. No, not the window sticker but the "place this sticker on your air cleaner so the technicians wont throw away your permanent filter" sticker.

 

[anmut]

HAHAH! The little octagon one - that is funny!

 

[1baddatsun]

is the 18 obnoxious i hear the 22 is not as loud i wonder if the performance is similar to the 18?

 

[TitanBlue]

Welcome to the M/F Club! I run a 24" x 3" SISO M/F. I don't know any other Titan with this setup. Love the performance.

 

[anmut]

There's a drone but it doesn't exist hardly at all on the low end and only within 1-3mph on the high end.

I read something about exhaust grounding kits that were supposed to counter-act any drone. Would be interesting to try.

 

[sudden urge]

You might not be the only one in the near future. I'm getting a new 40-1400 JBA catback delivered tomorrow. I really like the Magnaflow 18" I have on now, but if the JBA muffler doesn't sound similar to the Mag, I see a 5x8x24 going in with the JBA piping. The 24" Mag is 1" longer overall, part# 12279.

Hey Anmut,

I hear you man, I just had the Magnaflow 14" put on my '07 and the sound blows my neighbors Flowmaster 50 on his '07 away. He couldn't beleive the sound difference in the 2 trucks. He wished he would have gone with the Magnaflow.

 

[jhangs10]

Ya just got the 3" Magnaflow Dual in/out (18", part #12469) installed with 3" pipe on my 07 and it is so nice. Sounds great and noticeable power difference along with the Brute Force. The 3" is a little more expensive and I did a little more than just a muffler swap with adding the 3" pipe, but my exhaust is hidden away underneath, dropped just over the rear axle. Gotta love the Titan!
