exhaust advice

juganaut · 05-04-2007, 11:14 PM

Hey everyone First time poster, im new to the titan world and computers so please bear with me.I just bought my first Titan. I'ts an 07 crew 4x4 and i am totally stoked. I love it!!!!I'm looking for suggestions on cat back systems. Every sight I go to has them for the 06 and earlier but not for the 07 with the dual pipes to the muffler with 2 inlet and 1 outlet. I don't really know much i'm just learning about Titans but i'm ready to get into it and would appreciate any help anyone would be able to offer.

If you do a cat back system, Borla, Volant, Banks, Flowmaster will all fit.

I have the Volant, and love it.

Also Stillen makes one too.

looking at getting a new exhaust but dont want to pay 500-700 dollars so thinking about jut putting a muffler on and thats it im aslo checking this next week i found a place to do custom exhaust and debating between single or dauls all the way back any advice guys wanting to keep the good ride down the road but want it to come alive we i get on it

i,ve checked out all these systems and the problem is that the 07 titan runs duals to the muffler with single outlet. The 04-06 has a single pipe to the muffler with single outlet.These systems ( volant, banks, flowmaster ect...) will change the dual pipe system on the 07 to a single pipe system. Doesn't that kind of defeat the whole purpose.

Short answer? Probably not.

It's all about restriction, or lack of it to be more precise. I'd wager that any of those aftermarket exhausts are overall less restrictive than the stock exhaust of any of our model years. Having said that, I don't know what the reason for the change was in the '07 models. Most of the HP difference in the '07 has generally been accepted to be a product of the VVT on that engine. I've not heard of it being attributed to rerouting the exhaust slightly.

Think I might be better off just putting a dual inlet/dual outlet flowmaster in place of the stock muffler ( or any other brand ex/magnaflow) and just adding another tail pipe

The dual head pipes on the '07, I'm not sure about? But Carbeaux put it nicely, I don't see why Nissan went dual head pipes in and single tail pipe out?

When I had my custom Flowmaster exhaust installed they basically cut the stock muffler off, left the stock head pipes on, and made custom dual tail pipes. They were not mandrel bent, and they were 2 1/4". The truck felt the same, even power felt the same. This was not the case when I went to a 3" pipe.

If you are thinking of doing a cat back system, then it don't matter if the stock is dual to the muffler. Because you are removing everything.

Thanks for advice. One more question, does anyone know what size the dual pipes that go into the muffler on the 07 are, or an easy way to measure. Can't take muffler off to measure, muffler is welded to pipes on inlet side and I want to order new muffler ahead of time.

PM Aquaholic he has an 07 that he put a flowmaster 50 delta series dual in single out on his truck and he loves it!

Titanequipped · 05-09-2007, 12:14 PM

Jug - I too have an 07 dual in single out. The factory exhaust on our trucks is mandrel bent (2" in I believe) 2.5" out. I think replacing just the muffler would be as good as any aftermarket system, because of the dual mandrel bent exhaust. That said, get a high flow muffler 2 in 1 out and save some money. You can ask guys here, but I believe the 2 in 2 out is louder than the 2 in 1 out.

PM me, I'll go through my decisions with you if you want. I have an '04 that I went dual-in, single out, and out the door I paid $280, with taxes.

Or there was a thread on cat-back versus custom exhaust.

Justintoxicated · 05-09-2007, 02:54 PM

Stillen has one that uses dual in single out for 07's just a litte more pricy than the ones for the 04-06. Same HP. The Y-pipe is a good thing if you wan tto keep any lowend for towing etc. if you do alot of driving at high RPM's or drag racing then I think it would be more important to remove it at the cost of some low end grunt.

Yea so not much difference in 07 exhaust not sure why Nissan Changed it. perhaps it was easier to manufacture or install this way...

When I figured it out there was not much difference in cost between just changing the muffer and adding a tip than buying a complete exhaust. Just figure that getting the complete unit would be the way to go, unless your handy with tools and a welder.

Just do this and never look back! The ability to adjust the sound levels is worth it's weight in gold!

3" Supertrapp exhaust installed!

juganaut · 05-12-2007, 02:45 AM

Been out of town a few days. just got back and loged on. Some great suggestions,thanks everyone. I like that supertrap setup you posted mantis. Great idea I never even thought of going that way. I am know. Ill probably chek out that stillen cat back too just for kicks but the sound clips you posted of the supertrap sounded great. Love the thought of being able to adjust it with the discs. Just have to find a good shop where I live to have the pipes bent up. Open to suggestions for the Boston Mass. area
