Have a race car and looking for a way to make instant horsepower? Invidia’s downpipe is always a good start. This particular downpipe was tested and documented in the late but legenday Turbo magazine. They concluded that when combined with the cat-back section, the HP gains were seen up to an astonishing 60+ at the wheels with engine management.

This downpipe is made out of 304 stainless steel with a larger bell mouth. The piping ID is 3”, and should bolt up to most catback or stock units.

Please note that because this product replaces/removes an OEM emissions control device, we must state that this catless downpipe is for off-road use only.



Worth the money

The end of the downpipe didn't match up with my cobb catback .. 1/16-1/8 inch gap after installing the gasket, going to have to go to a shop and have them figure out the best way to fix it... overall can't complain, its a fairly cheap pipe, sounds great with my tomei el headers/up pipe and cobb catback

Car came with an unknown brand 3 cat-back with a 4.5 tip. I was afraid without the cat it would be too loud, but it is purrrrfect! Running stage 2 with Cobb EBCS. Perfect fit, great sound, no boost creep that I've noticed, and the added power is absolutely wonderful. I don't see anything wrong going with the cheapest option for your DP.

Couldn't be more happier. Looks good, light weight. Easy to install, expect the part of taking off the stock DP. Love it.

Great price, great upgrade.

Had a vendor order this for my 2002 WRX through RSD. Makes your exhaust tone meaner and the stage 2 map is a huge upgrade. Be prepared to snap some bolts on your old downpipe when you install this.

Just installed this on my 04 WRX wagon and man I love it! Paired it up with an Invidia N1 catback and it sounds amazing (with a cobb AP stage 2 tune aswell) Only trouble I had was hitting the bottom bolt you can get it with a wrench from underneath. All it takes is some PB blaster and a can of man to break the old bolts! Overall amazing product and RSD kicks ass aswell!

    Is the Invidia Racing Series Cat Back Exhaust with Titanium Tip bolt on with this down pipe?

    • A: Yes it will bolt directly to that cat back exhaust.

  • Q: Fitment  firstdrop 1 year ago


    Will this down pipe fit seamlessly to a invidia q300? And will I have to buy any extra hardware? Thanks

    • A: This downpipe will utilize OEM hardware, you will just need turbo to downpipe gasket and then a 2 bolt 3 inch gasket to mate the downpipe to the catback.

  • Q: gasket  terrinpreston 1 year ago


    does this downpipe come with a new gasket that goes between the turbo and dp?

    • A: It does not, you will want to order the turbo to downpipe gasket.

  • Q: Does my 02 wrx need a Cobb or a tune to have a catless down pipe?  mxrider327 1 year ago


    • A: A catless downpipe will need a tune at minimum, although catless downpipes typically exceed the flow of the stock internal wastegate so either a ported wastegate or external wastegate is needed to avoid boost creep.

    Will this pretty much straight pipe my car ?

    • A: This is just a downpipe and would remove catalytic converters, a full straight pipe would be removing mufflers and resonators from the downpipe back as well and that depends on the catback you run.

    • A: You think it would work with a borla catback ?
