Dirty Deed race exhaust dyno tune

Has anyone dyno tuned before and after on a stock 2.5 gen tundra WITHOUT the supercharger? The exhaust sounds great, but its pretty pricey and Im wondering how true the claims of about 49hp/89 tq are...Im torn between saving up for the exhaust vs saving up for a project car since the prices would be about the same....

 

@dirtydeeds can tell you all of that and how the exhaust was designed and tested

 

OTT has dyno charts and tune for completely stock Tundra.

 

Here’s JBA long tubes with dual 3” exhaust no cats. No supercharger.

 

I don’t have time slips from that long ago, but the system was good for .9 on the 1/8 Mile. I’m other words, 0-80mph is almost a second better

 

is the dual catback 3” ID or OD?

 

Exhaust is made from tubing. Tubing is measured from the outside. Pipe is measured from the inside.

 

Ha! I just bought my third exhaust system from Keith and I'm STILL learning stuff!
