i was thinking of maybe geting the HKS, but that is if i dont get a 20g
a 20G does not replace the downpipe. It only gives an elbow that goes to the stock location of the downpipe so you still need one.

And if you want the HKS, you are stupid. It is the worst flowing, smallest, and biggest POS downpipe there is. Go research some more.

If you have a cat back it will be from "the cat back" . it bolts up to the stock cat. When you get a dp it usually eliminates the upper one. Then you need to either get a highflow to replace the lower on or a test pipe if you want it gone.

If you have a full 3" exhaust the stock cat is a big restriction. Its smaller than 3" and usually after this long they are pretty clogged up.

If you're not going to replace the elbow you don't need to spend a lot of dough on a big DP. but if you're planning on upgrading the elbow get a good one.

the defcon one is good and so is the cooleze. Becauseican makes them on the forums but the lead time is a bit long I think.

I have a cooleeze in the mail right now. I bought it because it looks like its got really thick flanges and a flex section. They say the flex has no bottleneck and it comes will all the hardware. I'd recommend just e-mailing the guy or go through ebay rather than a store that just jacks up the price. And yes, you'll need a test pipe. He added one one for me at 50 bucks.

yeap i think everyone would agree with ^^^ BIC DDP or just a regular BIC downpipe....

think his name is randy and his name on the forums is becauseican...go do a search and find his webpage, he sells downpipes as well as other parts.

the only problem you'll have with the BIC ddp is if you go with the 20g. The BIC pipe has an integrated elbow, will only fit stock turbo output.
