Turbo Back vs Engine Back Exhaust
Hey all, posing my first thread hear at WRX Tuners. I bought a 2012 WRX Sedan back in February and love it. At any rate, I am planning on doing a bit of tuning once my warranty is up so my R&R (Research and Refinement) is taking place now. Through research thus far, I've gotten the impression that an exhaust system is a great first place to start when tuning your WRX. What my research has told me so far is that if I'm going to upgrade the exhaust system with gains in mind I will have to at least get a turbo back exhaust. I'm leaning towards an Engine back exhaust, but my main question is: What am I gaining/loosing by going with or not going with an Engine back exhaust vs. a Turbo back exhaust? I've been told that the upgraded headers in an Engine back exhaust are "equal length" which gives better/even flow of the exhaust gases? How necessary is this in the grand scheme of things? With the future in mind, and more potential upgrades to follow which route should I go? Thanks for the help!

If your building a monster, go with EL's. but if your only looking to stay in the 300-375hp range, it's not needed.
What are our plans for power gain. Your suspension will need to be built to match most power gains as well.

Thanks for the Quick Response BLAZE! I honestly think I would like to stay within that 350-375 range that you quoted. Seems reasonable and keeps the car practical for a daily driver still (I think). For cost purposes, it seems like I could get away with Turbo Back according to your post. Now, lets say I get a little extra spending money; could I just add the EL's down the road without problem?

In regard to your suspension comment, I honestly was considering the Perrin Performance WRX Suspension Combo Kit. [url=]PERRIN Performance — — Subaru 2011+ Sport Suspension Combo Kit[/url] Does this seem like a practical way of getting my suspension where it needs to be. I like the idea of Coil Overs, but idk if I'm SUPER interested in them at this time. Seems like a lot of chedda just to be able to actively adjust my ride height. Pursuade me otherwise I suppose!

I would pick another brand. Perrin the the last company I'd pick for suspension.

Coilovers are a wanton waste of money unless you regularly race the car on the tract on a competitive basis.

Thank you brfatal... Dually noted. Would you consider Perrin Performance a Go-To vendor for anything WRX tune related? Also, who would you go to for suspension related mods, brandwise?

TiC for suspension goodies

Although I never had a problem with my Perrin sways and endlinks in the past, others have. That could be said about just about anything. Install error is common too.

Whiteline is popular, just do research on your year as to what endlinks will fit correctly with THAT bar.

Here's another place I would start :

buy the brushing type front endlinks. Solid metal front endlinks will drive you insane.

There is no company that does it all. Honestly you're going to want to mix and match. Whiteline, Eibach, and RCE all make good sway bars. Kartboy endlinks are the most reputable. As for springs, WRXs don't tend to like being lowered much on the stock struts.

Perrin makes a few good things here and there, but they are not one of the aftermarket better companies.

Thanks again everyone for the input. It all helps and definitely opens new avenues for my personal research. For now I'll go and delve into what you have all provided me and see what new questions arise. Thanks again everyone and stay "tuned"!
