Default downpipe with highflow midpipe choice?

first of all don't flame be for not using the search button. I did and just got confused all those name brands out there and ones i found doens't meet my needs. For example the new catted Helix, but the location of cat is right after turbo.

Basically I am looking for a dp with highflow cat on midpipe section with 3 inch piping. Really have no idea what are some choices...of course with resonable price.

So far the only one i know is random tech (which uses donut gasket) and I have a flat flange catback so that won't work. The cobb one seens very nice but I really don't have the $600 budget. Anyone options? cheaper? Either one piece or two piece would be fine.

thanks

Stromung, turboXS, Cobb, PDE to name a few.

Stromung is a good choice, the dp is around 180 and the 3rd cat is around 320. So it's cheaper than cobb or pde.

basically any downpipe that doesnt have an integrated midpipe will work. Any "full length" downpipe will replace both cats and may or may not replace one cat. If there is a cat, its not goin to be in the midpipe with an all in one pipe.

Like wimp said, stromung, bosal, turboxs are all strong contendors

Default try this

Since I dont have ten posts yet I cant link a URL, go to the Newbies and FAQ forum and do a search on "Popular Downpipes" by fliz. Its a spreadsheet that lists every DP you can think of with all the stats, awsome resource.

Just curious why you want a DP with the cat farther away from the turbo (not faulting the decision, just curious).

The 3rd cat is the least restrictive. Whether or not that's the reason he wants it there, I have no idea. At the same time, the 2nd cat is more effective for emissions.

Also, check out the B&B downpipe. It's a full-length dp w/cat at the midpipe location.

the reason i am thinking about adding the 3rd cat is due to inspection purpose. Some mobil police station are being setup up around where I live and i heard police are using mirror to check the exhaust system. I figure i'd rather sacrafice 5-8hp just to be safe. So at least they'll see a cat there... it is a 10k fine for each cat removed. I was also thinking about just get a set of heatshield to put on my dp so it looks like there is a cat..but the color won't match and looks too fake..

well if you're really worried about it, i would gut your up and down pipes and leave the 3rd cat in place. that way everything looks stock from a visual stand point

I would not gut your stock stuff.....what if you needed to return it to stock? If you resell the car and it wont pass inspection for the new owner, you may be liable.

Check out www.daddysscp.com. Rich can answer all your questions and offers some great products.
