Looking for Dyno numbers

[CELLTECH25]

Hi all...with so many companies offering after market parts I still find it hard finding any dyno proof that anything actually makes a difference in horsepower. I am in the market for a few bolt on upgrades like Headers, Test Pipe and Cat back as well as an intake system. If anyone has taken there car to the dyno and saw a difference after they installed upgrades please post the part, manufacturer and the gain in HP info if you don't mind. Thanks.

Most of the Reputable exhaust companies will show you exhaust gains, except for the headers, they are still new but I think there are only two right now, borla and agency power... The intakes.... Most of them use MAF trickery for gains, find one that doesn't, I prefer the Perrin intake systems. I know this isn't what you wanted but maybe it helps

Perrin is a good choice for intakes. They have a blog you can visit with some more info on their intake.

For exhaust systems they should all do the job by freeing up the flow. Test pipes are all the same really..

aFe dry intake, Perrin crank pulley, Invidia N1 cat-back and front pipe with a high flow cat. AT on the Mustang dyno at Evasive Motorsports, 176WHP/140FT-LBS TQ. Hope this helps.
