Anyways, my point all along was that i dont like ScoobySport products and that he should get something else... like Vishnu. I don't know what BAN SUV's is trying to prove... but I'm just trying to help someone make a better choice on parts for their car.

 

That's the comment that prompted me to discuss the performance losses of a cat vs. a bad downpipe flange. Of course a twin dump pipe makes more gains (according to most people you ask) but it is more expensive. That's why most companies stick to bellmouths.

Regarding emissions- the Vishnu system, like any other system, does not appear smog legal because it's clearly not factory. It does however meet the actual emissions content requirements in all 50 states. Being turbocharged is certainly not a factor in favor of this however.

The quote you supplied about the Scooby Sport is from one of their vendors, not the manufacturer themselves.

Anyway, in the case of pointing out the build quality of Scooby Sport relative to most other systems, I agree. I was not defending any particular system over another, merely pointing out the error in an opinion about what makes one exhaust perform better than another when it comes to power. Please don't take it personal. When I see information on these forums that I believe to be false, misleading, or simply mistaken, it is my place to correct it to the best of my ability.

 

bump, more pics on the way.

 

okay, here are some pics of dropkick_muppets downpipe. i'm also going to start another thread to try to figure out whether it was made by H&S or JanSpeed.

Go here if you would like to see larger and higher quality images.

 

check out this thread as well if you're interested in seeing whether this is an H&S exhaust or a JanSpeed.

 

looks like the vote is 9-0 in favor of H&S, which is precisely what i thought. i should be installing it next week, so we'll see how it does in the power department.

 

I do not mean to be critical of someone's personal preference on what downpipe they purchased, but I would have to say that the ScoobySport dp is not a good bang for the buck. The price is high, especially for a pipe that retains the 3rd cat. If retaining the 3rd cat was the sole reason for the puchase, a better choice would have been the Bosal dp. It uses a divorced wastgate design, which seems to be the prefered design, bolts up to the 3rd cat pipe, includes all the gasgets, is well made and can be puchased for around $200.00. If money isn't the issue, than a 3" dp that removes both cats and includes a high flow unit (Turbo XS, Vishnu, Perrin) would be perferable, I would think.

 

hey, no offense taken. the reasons that i went with the scoobysport are as follows:

1) design -- i wanted a bellmouth pipe that would retain the 3rd cat, and bolt up to the stock exhaust system. i was under the impression that the bellmouth design was the most effective.

2) i didn't want to shell out $1000+ for a full turbo back. money was an object, but the differance between the $380 i spent, and the cost of something like the Vishnu pipe wasn't an issue.

3) power -- like i mentioned before, i was under the impression that the bellmouth pipes made the best power, particularly in the low and mid range.
