Gasket ???

[Little6pack]

OK here is a dumb question again.
I bougt a test pipe off ebay that is brand new. I am not sure if it is home made or manufactured. I need to know PRIOR to taking off my CAT if I will need a gasket for the flange area??
I made the mistake of going to PEP boys because I have a few gift $$ coupons to burn.

I walk in with the pipe so I could match a gasket.. The counter dude said I don't need one?? I say HUH? Then he back off saying maybe you need one but we don't do exhuast systems.
now he got me confused.
Honestly I would think one is needed But I have been wrong
many times in my life.

I can't tell by looking at the cat while hooked up in my car & I don't want to take down unless I am sure I have all the parts
READY to Roll.. ( you know I hate to run to parts store in the middle of a project.)

Thanks

You don't need a gasket. I use the red RTV on there with good luck. Ran it like that for years.

AS usual i was wrong!

I Have a tube of the RTV red leftover from the BIG BAD 455 Goat motor assembly last year

You don't need the RTV either. Flanges should be flat however.

Won't hurt though.

headgasket Q

going to be replacing my head gaskets (pretty sure i have a bad head gasket ) What gaskets do are the norm for something like this. what else should I do while im in there, lifters timing, chain,pushrods , cam ect. the car has 80000 miles thanks

No gasket here, no RTV either. We took the original catalytic clogger off my car a few months ago. We had to use an air chisel to "cut" the old one off, and had to cut 2 of the old bolts. You said the test pipe was new, so you'll be in good shape. Mine was used and I had to get a pipe expander to get it to slip over the DP.

BTW, on my basically stock car running pump gas, I installed the test pipe and put in a Power Plate. Next visit to the track I gained 5 tenths in the 1/8. BAM!

Do a search in this forum for "Power Plate".
Get a cup of coffee first.
TONS of good reads.
I don't have numbers to back it up, but I believe.
