Downpipe with cats question!

[xXEclipse]

I bought my 98 GSX catless with a 3in Downpipe... My question is.. can i put a aftermarket cat on?? Without removing the downpipe?

Yes you can put a cat but if you're not putting it on the downpipe you will have to cut and weld it to the catback.

what kind of catless downpipe?

Is the downpipe extended so that the cat pipe/test pipe is not needed? It would meet up with the cat-back exhaust.

If you have a regular downpipe and its catless because you have a testpipe, then just remove the testpipe and get a cat put in with 3 inch flanges on each side. Make sure you measure the distant.

I have a a 3 in downpipe and the guy straight piped the rest... I heard its not good to put a cat on a 3in downpipe... is this true?

there are many people out there running high flow cats on 3inch exhaust systems.

It's not good for fitment, performance or what? Almost any exhaust shop should be able to fix you up for a relatively low price for welded or bolted.

Good for performance and fittment? Idk...
