Please help with Dual Exhaust Question

[Verndog]

I am going to run true dual exhaust all the way back. I've read tons of threads on this and still am not 100% on this crossover issue. I've read that you don't need crossover with 2 cats....and I've read that you do...

Question 1 will it improve performance to run crossover with 2 cats, and must it be before cats.

Question 2 after the dual cats should I use 2 resinators if I'd prefer to keep noise levels low.

Question 3 what mufflers would you recomend to keep noise levels low but not sacrifice much in the way of performance.

BTW...I'd rather spend a little more up front, and do it right...and I am having the work done at a local custom shop..

Thanx All
Kevin

I'd just use QuickTime performance electronic cutouts. Do a search for them. Member mjjoff has them.

Ok...I ran the search...I got one other thread with info on these electronic cuttouts. It looks to me as though this is just a open / close switch for a straight pipe. Not my style....I do not need to piss off the world with a brand new truck....thanx for the help though.

3.) I'd go w/Flowmaster Delta Force 50's w/o the resonators. I have a FM Delta Flow 40 and love it. I gained .5 mpg and got a great sounding exhaust. FM says that the 50 is quieter but still has the performance.

Just make sure to stay w/the stock piping diameter of 2.25".

Hey Kevin,

1.) You'll probably lose low end torque if you don't use a crossover.

2.) Just go w/the mufflers.

3.) 3.) I'd go w/Flowmaster Delta Force 50's w/o the resonators.
I have a FM Delta Flow 40 single in/dual outs and love it.
I gained .5 mpg and got a great sounding exhaust. FM says that the 50 is quieter but still has the performance. Spintech mufflers are highly regarded on the site, too.

Just make sure to stay w/the stock piping diameter of 2.25".
Check out my pics for my FM 40 set up. JB

If you don't want cutouts I'd go with Spintech.

Thanx Jack...

So if I'm going to run a crossover anyway (sounds like I should), then wouldn't it be smarter to just stay stock up to the muffler, then y out into 2 there? (dual mufflers)

Jeesh...confusing with the options...

Also on your system does your muffler make the 1 into 2 conversion?? I other words do tou have just 1 muffler??

Also...yes I plan to stay with 2.0 or 2 1/4 max pipe dia.

...

If you don't want cutouts I'd go with Spintech.

Keipher...can you tell me from 1 to 10 how loud the spintechs are?

Thanx for the help again

Kevin,

I have one muffler that has two outlets that are dumped after the axle. I went w/2.5" in and 2" out. I'd suggest staying w/the stock set up and replace the muffler and maybe the pipe after the 3rd cat/resonator. Check w/V8 Toilet about the Spintech muffler if you're interested in it. You can always add headers if you want more power later. JB
