Well i have the banks system and i love it. it may spool your turbo a lil faster but it will mostly lower your EGT's which is the best and what u want. you may get a few horses but not many. and you will not harm anything but only help.





I would go with the banks system

Personally, I've used Gibson now for my last few vehicles. Mainly because they build a quality system and I like the sound quality and level.


I would think any brand that is 4" and mandrel bent would be very similar as far as perfromance or EGT improvements???


If so, then it comes down to price and sound and those are personal choices....

Vin:


The changes you would see would be lowered egt's enabling you to increase your hp #'s with a fueling box, quicker turbo spool up, and possibly a slight increase in mileage due to the better flow. No harm will be caused by improving the factory system. We recommend the DPPI exhaust which has three different choices of materials to satisfy all customers weather climates.

After researching extensivlly I decided to go with the Hog Performence exhaust.And after getting it last week I can't wait to install it. I feel it is far superior to any other 4" stainlass exhaust out there. It is the only one that comes with band clamps rather that the other guy's standard exhaust clamps. A choice of the 3 different mufflers and 2 different tips. Check it out at www.hogperformance.com
