Top Speed's Cat Back System Installation

[jb92563]

I just took the plunge as well but being in CA I can't delete the CAT's, however I have heard that at least one person in CA removed the 2ndary CAT's and it still passes CA smog tests.

Anyone else in CA remove the 2nd CAT's?

Got the System today from UPS at 1:30pm, (3 days from order) started the install at 2pm, finally had the old muffler out at 3pm and got all the new stuff installed, cleaned up the tools and took the car off the jacks by 4pm.

Its pretty easy using liberal amounts of WD40 so all the clamps slide easy and nuts come off without much trouble.

I did waste about 15 minutes trying to put the U pipe between the muffler and 2ndary CAT back in place backwards and wondered why it would not fit....duh!

Once I got that sorted out everything went together quickly.

Its an easy DIY and I did shim the muffler back towards the rear about 1/2" so the nice tips stuck out a bit more.

I did the before and after exhaust video and the shim pic which I'l post this weekend.

No instructions to add to this thread as it has everything well covered.

I did! Secondary cat eliminator pipes, Fister/ Pedro mod. and I passed
smog in San Diego. Well below limits.

Was it still quite enough without the 2nd cats or does the sound level go up significantly?
