I was considering just getting someone to bend and weld me some dual pipes fromt he cat back. 2.5 inch i guess.

Since the car is NA (for now) would straight pipes, just from the cat back, hurt it more than help it ?

and

does anyone recommend someone for this type of job ?

 

Test pipes will sometimes throw a cel and also could mess with your A/F mixtures since the ECU reads off the cats. IMHO I'll get HFC
