How many of you have tune or just dyno your cars after installing HR Ypipe, coupe middy, axle back mufflers, etc? I'm interested for comparative purposes in results after installing OEM upgrades. Please post just related mods. I'll start since I tuned recently:

2004.5 53K+ miles
Stock airbox plus ztube
3/8 spacer
High Flow Cats
08 350z Y pipe and Middy
stock muffler

My car dynoed at 84F 227 whp 206 wtq in a Mustang Dynometer tuned with Osiris.

 

Moved to exhaust section.

 

No one?

I've been reading tons of post of people giving opinions about exhaust's possible results and no one have dynoed their cars to get real results? I don't mean to make direct comparison here, but it would work as a reference.

 

most people that stick with OEM exhaust are doing it because they don't want to spend money. Putting your car on a dyno costs money...therefore most dont do it.
