Bosal's polished stainless steel Twin Dump Racing Downpipe offers fantastic performance and a show quality look in a Twin Dump downpipe design. If your not buying a Bellmouth or Twin Dump downpipe, then your not getting the performance you deserve and with Bosal giving us a great pipe at a price anyone can afford, it's no wonder that this is one of the most popular downpipes around for your WRX.

Pros:
noticeable hp gain/easy install
Cons:
was a bit tight on the fitment but made it work- should use thermal wrap
Great downpipe. Noticed hp gain with avc-r. Easy install without too much trouble. The only problem i had was that the bracket that bolts to the tranny didnt line up (heavy hammer fixed that). I recoment using thermal wrap because there are no heat shelds to protect the tranny.

Pros:
Looks good, conrstuction is solid, and performance is great.
Cons:
Fitment is a 7 out of 10
Theoretically this product is superior than the rest. Twin dump design is said to be better by almost all turbo engine builders. It has the standard 14+ inches of wastegate drop before it re-enters the main dump tube.
Installing was a lil rough but it came with gaskets for both sides and with little help from mr crow bar she fit right up.
Thanks JSPEC tuning for such a great deal.

Pros:
Price, twin dump, retains factory cat
Cons:
Fitment is a bit sketchy
Great product for the money. The fitment with the tranny bracket is questionable, meaning bending might be required. Also, while I did not have an issue with mine, I know another member that had issues with the wastegate flapper getting stuck on the divider plate between the dump tube and the main dump. Just took some grinding to remedy it.
The power gains with the stock turbo are great, and the turbo sounds fantastic with this downpipe.

Pros:
Beautiful peice, noticable power gain, sound
Cons:
fitment takes some work
The twin dump is the so purty under teh hood and the power gains are noticable which is nice. Also the sound of the turbo is very sexy now. Fitment is a bit off but nothing that the hammer can\'t take care of. Definately a great product.

Pros:
Divorced piping, less flow turbulence from turbo to exhaust, and the spooling sound of the turbo
Cons:
minor fitment issue
This downpipe is a good bang for the buck whether it was purchased used or brand new. After having the downpipe installed, my wagon had a noticable gain in power. The car definitely pulls harder than the OEM setup. Since this polish piece has a divorce-piping design, the turbulence flow is dramatically decreased. This is definitely a great product for those that want to increase the power while maintaining the low noise level close to OEM settings. However, the sound of the spooling turbo is much more noticeable, which is a plus for personal preference. ^_^ Furthermore, since the Bosal downpipe is a shorty downpipe, it allows one to keep their second catalytic converter on the OEM downpipe. With the second catalytic converter still intact with the rest of the exhaust, the odor of the fume going out of the muffler is not terribly worsen. The only issue that this piece has was a minor fitment issue. The pros of this product definitely dominate the con of it. Overall I am very happy with this investment.

Pros:
Power,sound and build quality
Cons:
useless mounting arm
Great down-pipe! Love the whistling sound from my turbo and good power gains. I just cutoff the mounting arm, made for easy install. Glad i wrapped mine, but would love to hear the difference without it.
