This is a discussion thread titled "Borla single or dual? spintech?", within the Engine & Drivetrain forum, part of the Technical & Vehicle Assistance Forums category.
ive researched many exhaust threads and have gave advice to others, but i am stuck in my own footsteps. Im just about ready to order my exhaust this weekend. At first i was interested the borla duals- the look, sound and power of them interested me. then after a while, i looked at my wallet and realized needed all my money for the lift, so i considered the borla single- cheaper by $200, more performance, same sound. I dont perfer the look of a single tip, so i was thinking about taking off the tip to make it look like i have dumps. But now i miss the idea of having duals.
Ive heard some talk about spintech performance mufflers. Ive never seen it advertized though. Only from word of mouth and fellow TS members. If Im looking for the sound of a borla from the spintech, which muffler should i go with? duals or single?
In your opinion and experience, what should i go with?
Borla single? Borla Dual Sides? or a Spintech set up?

I had the same delema, til I heard "v8toilets" Tundra. He is using a Spintech Sportsman XL. It sounds great to me. I want the muscle car V8 sound that won't piss off the neighbors. I agree with you that two tail pipes looks good, but his single in/single out sounds just right. He had mentioned they make several differant configurations of this muffler. I hope to put one on soon.
I have been looking for stuff to accidently drive over. This will help justify the cost of putting a new muffler on my new truck to my wife.
You may want to consider going the custom route. I did and am totally satisfied. I got excellent sound (tone), very little cab noise, picked up just under 1 mpg, and have increase in power from 3000 RPM and on. I don't notice much if any difference down low, but at 3500 it kicks in like a 4 barrel!
I have true dual from where the y pipes meet the cats all the way back. I used 2 1/4 into Flowmaster 70s and removed the factory Y pipe and put in a H crossover. Total $650.00....and this shop was expensive compared to some. If you check out this route, ask around and make sure the shop has done a Tundra before...2 out of the first 3 shops I went to recomended the one I ended up with.
Wow, looks like they did a clean install! Im getting a quote from Sweeny's in Torrance today for a Spintech sportsman street dual/ single w/ high flow cats. I think im gonna take out that 3rd CA cat.
This is the setup im looking for since the spintech mufflers are relatively small, so i might run 2. So i was thinking 2 Hi flow cats through an X- pipe, 2 single/single sportsman mufflers, dual cat back exhaust. 2" piping
Or- 2 hi flow cats, Y pipe, single in/ dual out sportsman, dual cat back. 2.25" piping.
Which one seems better?

I'd most definately choose option 1. This truck was made for dual, and sounds like music to my ears...not annoying with 70 series. Spintech should be similar in good sound low noise option. As long as you keep it at 2.0 or 2 1/4 max, and a X or H crossover, I think you'll not be disappointed. I went to 2 1/4 because they say it is a thicker wall pipe, and they were set up for it.
Take a close look at the stock Y pipe...I posted a pic of it. It really is a weak point in this system!!
Ive been crusing around some exhaust shops today, and i mentioned what i was looking for as of sound and power. They replied by saying running 2 mufflers will make the truck harder to breath because of the open velocity of the system. Did this happen with your system?
BTW: I dont want to go too far into this system. My budget is like $350

Total bull. Backpressure is always bad.
What happens is that if the size of the pipe is too big, the speed of the exhaust gas sound pressure waves slow and you lose bottom end. "... too little gas speed tends to make the power curve excessively 'peaky' hurting low end torque. Larger diameter tubes allow the gases to expand; this cools the gases, slowing down both the gases and the waves." http://www.burnsstainless.com/TechAr...ry/theory.html
There's no advantage of duals except the sound.

The only real advantage of duals over a correctly sized single muffler is that the duals give you better ground clearance due to the smaller diameter of the mufflers.
Adding an H-pipe crossover gives the duals more power. Adding an X-pipe gives more power than the H and about equal to a correctly sized single muffler.
I don't much like the looks of the stock Y-pipe either, but the only fair comparison would be with a good y-pipe like a Dr. Gas vs. duals. I think that the Dr. Gas Y & X pipes are the best for the price that I've seen, but there are probably others. Compare the Dr. Gas Y-pipe to the JBA...the JBA looks like the kind of fabrication I do! I know, the JBA pipe is bolt-in, but it sure looks to me like the Dr. Gas y-pipe will flow better, and any muffler shop can do the welding. http://www.drgas.com/street-cat.html http://store4.yimg.com/I/tundrasolutions_1745_618012

My experience has been this. I’ve tried the TRD duals, which are a cat back exhaust system that connects right after the factory y-pipe and lost a very noticeable amount of low-end torque. The TRD duals are a single 2.25’ pipe and dual 2.25’ pipe. Why double the outlet size? I hated them! I couldn’t tell if there was any top end power gained because the increase was small and to be honest I don’t care about 6 horsepower @ 4500 RPM. I’ve tried the JBA Evol 2.5” single exhaust and noticed a very small decrease in low end torque. The sound was OK but it droned slightly on the highway and I do a lot of highway driving. It was nicely built though. I couldn’t tell if the top end power increased really with the JBA. If it did it was too small of a difference for me to tell and again who cares about 5+ horsepower @ 4500 rpm in a pick
Borla single or dual? spintech?
