Just wondering if anyone makes a down pipe and high flow cat that connects to the standard exhaust? Seems like a way to go if you want to keep the system near to original but free the flow up.Correct me if I am wrong the two original mufflers are straight through.

I hear KTford knows a reputable dealer of high performance cats ;)

I think I remember reading though that the turbo pipe on the xr is already free flowing enough.. the restriction is in the rest of the system on low boost applications

Std dump pipe is 3" already, so you dont need to change that, major restriction with the whole cat section.

you will also gain a couple kw by removing the centre muffler.

Ive tried and tested a couple systems, PM if you want a link to my dyno sheets.

Check out the thread beauies has mentioned previously.

Showing some huge gains, seemingly by seperating the Exhaust and Wastegate flows from the turbo.

Std dump pipe is NOT of efficient design.

And std cat is quite a good unit. Better than the aftermarket high flow cat I had installed (25rwkw better in fact)

Just a shame the std cat couldn't handle the power. :spoton:

that doesn't make sense dude! if the standard cat makes 25rwkws more then your current aftermarket cat, then it does handle the power and your aftermarket one doesn't!!

please explain??
