SPD turbo exhaust adapters

Hello Folks;

is anyone using the turbo exhaust adapters without any other mod. What is your take on them. I plan to install them. but not thinking of doing any other mods to the truck

Ask SPD for before and after dyno charts to back up their claims.
Betcha they refuse.

SPD has a dyno chart on their website...

Interested as well, the theory seems sound with the larger outlet to get more air out.

I know a lot of people are using them. Anyone feel a seat of the pants difference.
I plan to give them a try at some point....

Do it! installing spd turbo adapters today

Just ordered them too.

I did them.

They seemed to do absolutely nothing.

It made no difference to timed 60 and timed 100. At least for me...

Maybe they’d make a difference with Downpipes... maybe other folks have had better luck.

On the bright side they didn’t hurt anything.

I won’t do downpipes. Very little horsepower gain, but a whole bunch of noise.

you wont really feel a difference of 20hp in your pants.

I like my SPD adapters.
