Headers.... Performance & Brand
Ok... last weekend I put on a Corsa exhaust on my 06 SUT... VERY happy. Gives it a nice tone, and really has seemed to help with gas mileage and a little bit of performance.
I keep thinking supercharger, but that is a ton of money for me to go dropping into a vehicle that I really probably will get rid of in 2 years or less.
I have heard people talk about the Dynatech headers, but DAM* those are pricey! Are they really worth the money? Will I not see the same difference if I get a set of Borlas?
Are there any brands that anyone has tried and has been happy with?
Any brands that people DO NOT recommend?
Any other cool performance upgrades?
Thanks!

Re: Headers.... Performance & Brand
You may want to strongly consider a custom map (tuning) after installation or you will run too lean.

Stay away from Edelbrock, the welds break and they don't stand behind them! I found out the hard way..

Re: Headers.... Performance & Brand
i have dynatechs on my camaro and they are the best headers i have ever had, period. Instuctions are REALLY straight foward and the welds are great with the stainless.
I would stay away from the hypertech from anything tunning. Get hptuners and you have a hard time fguring out, there are tons of ppl that have used and im sure you can find help.
I would say that they are worth it. However, keep in mind, you exhaust tone WILL change, for the best of worst, thats up to you. Keep that in mind.
good luck!!

Re: Headers.... Performance & Brand
I had 2 sets of the Edelbrock break on the drivers side collector. I have two other friends with H2's and the same thing happened with them, always on the drivers side collector.
