|||I am using a Borla Hush Stainless 3.5" exhaust and an Apex'i downpipe. It is tough, looks good, very quiet, and lets the engine breathe quite a lot better than the stock pieces. I recommend that you replace the up-pipe at the same time as the exhaust, as it will assist your turbo to spool faster, and is pretty inexpensive. Usually an exhaust mechanic will simply install the up-pipe for you and just bill for the exhaust job as one invoice. This is a good time to replace the turbo/downpipe gasket also. Many exhaust mechanics will offer this, but many will also just use what they are given without asking. This is an important seal, and if overlooked, will cost a lot of power. It is unlikely that the flanges of anything bought cheaply on eBay are going to be worth using. The flanges must be welded properly, and be of a thickness which can withstand temperature changes and shock. This costs money to produce, and these high-performance exhaust systems which you are describing are universal mufflers which are welded into a series of bent pipes which happen to match your car. Extensive tuning has gone into the better systems (Tababe, HKS, Borla, APex'i, Perrin, SPT) through research at the track, on dyno beds, and with many of the same model of car, so that a true estimate of increase in power can exist for us, the consumers. eBay sellers will often make a median claim, like "15hp dyno proven additional horsepower with use of our product", because 15hp can come from testing with the air temperature 3 degrees cooler. It can come from pump gas being so unpredictable, it can come from someone sneezing. On the dyno, it is a joke to assume that there is any real benchmark for testing of one exhaust on one car to another on another car, and these assumptions that a power increase will occur is correct, but throwing numbers around is really what the eBay type vendors with unknown brands are doing. The real race teams with company and product support have proven their gains in power with different parts through wins and losses, their records are public, and they cannot lie to us and stay in business. It also lets you have the peace of mind that if it fails, someone will support you in a warranty claim.|||No. Many of the products on ebay are not worth the price, such as Megan, OBX, and SRS. Look into TANABE, A'PEXi, HKS and 5zigen. The ones found on ebay usually look good for the price but can sound horrible and eventually crack making the check engine light turn on. Buy the right product once and don't worry about it in the future.|||My buddy has this exhaust on his wrx, it sounds great, he's had it on for almost a year now, no rust forming yet or anything like that. I had an X02 exhaust on my Legacy GT and that DID rust after a year, but the SRS seems to be better quality. Sounds really nice though!|||sorry but no, most products on ebay are cheap knockoffs.
Its worth putting up the cash for a good exhaust as the companies eg: like HKS ect put a lot of money into research...with a wrx you'll get a good sound anyway and that more about the muffler than the exhaust.
