Re: How a properly built exhaust system works

Hey everyone, I've been searching with no end so I'm finally breaking down and asking anywhere I can get a real answer.

I have 04 DC 4.7 that's Performance-wise stock (195k miles). It's the TRD Sr5 and my stock exhaust is falling apart. I'd like to put true dual borlas on it with an 'x' pipe to help with backpressure/drone.

My plan is to buy the mufflers, tips and get the pipe bent at a local shop to try and save as much $$ as possible. I'm not planning on doing anything with the headers. (at least for now)

With all that being said, has anyone had issues running this setup? My hearts set on borlas but I'm open to suggestions.

Can I use an OE Y pipe? Can I use OE cats and resonators without drone or back pressure issues?

She's a good girl, and I want to treat her right.

Re: How a properly built exhaust system works

Is there a shop around that has a true mandrel bender?

Re: How a properly built exhaust system works

An x pipe implies that youíre going to run dual exhaust. And asking to reuse the stock y pipe implies youíre using a single exhaust.

Youíll want to use a single exhaust if youíre running the stock exhaust manifolds.

Please feel free to give a call. Iím happy to help engineer the perfect exhaust system for your situation.

Okay, so I've been reading through most of the 51 pages of this thread to a point that I now have a headache. I'm going to be putting a new muffler on my 04 DC in a week or two and trying to figure out what muffler to use. It's going to stay all stock to the muffler. I don't want to loose HP or torque. I have a 40 series flowmaster now that is 2.5" in 2.5" out (pretty sure it hurt my low end). I'm wandering what my best muffler option is and what diameter?? Not sure flowmaster style is the way to go. Maybe a 2.25" straight through style like a Dynomax race magnum? Help!

Re: How a properly built exhaust system works

Great thread!

I've got an 2006 DBL cab that is in need of some exhaust work, noticed a hole about the size of a quarter where a support broke off.

Previously I had 3" cat back and don't even remember what muffler was put on when it was done. I tow a boat and am going to be hauling a 1600LB (I have airbags and load rated tires) pop up slide in truck camper around. Kind of always felt the 3" robbed some power and torque from the truck.

What would the proper set up be for a truck doing this? I want to do it right and will spend the $ for it.
