Default For those with custom exhausts - what size piping did you use and which brand mufflers?

I know very little about this topic, but am curious to know what people with custom exhausts decided to go with and what kind of power they're seeing from their setups. I'm thinking 2.5" test pipe and 2.5" downpipe, then split into two slightly smaller diameter sections going to the mufflers. Looking for a mellow sound (stock-like is fine with me), but as much HP as I can get. Any suggestions?

Thanks!

Default Not that many here.

If you're after hp, just get the Thermal Race + test pipe and be done with it. It is loud as hell though.

High hp gains and mellow sound do not go together btw.

We can supply you with a matching TP & DP. What tranny do you have?

Default What else would you like to know? :-)

From our website:
"High-Flow Catalytic converters are made to bolt directly to K03 &amp; K04 turbos. The HFC is a 400-cell Carsound converter that will pass emissions tests. They are built with laser-cut 3-bolt flanges and two oxygen sensor bungs for proper ECU readings. The inlet diameter of the HFC is 2.5" at the turbo"<ul><li><a href="http://www.tantrumwerks.com/html/18exhaust.html">http://www.tantrumwerks.com/html/18exhaust.html</a</li></ul>

Default Your shotgun pipe

It looks like a "divorced" pipe. Is that the case?


Thanks,
Andrew

Yes, but it merges back at the end before it enters the DP.

Default Fully divorced downpipe overkill? Or well worth it? I understand the thoery but

do divorced DP's make for substantial gains on high boost large turbo applications?

Thanks,
Andrew

Default The longer the split, the better you'll be...
