ok guys my buddy wants to buy the racing beat downpipe... but doesnt know if it will hook up to the stock cats... without a pic i have no idea what the exhaust looks like on a T2, only ones ive worked on are custom exhaust... so will it bolt up the stock cats on a 88 t2? thanks in advance

Nope, the racing beat dp is meant for custom exhaust or to hook up to the presilencer. The dp plus presilencer reaches stock catback location, but the presilencer is longer than the stock cat (stock cat 17.5" silencer 20" I believe) so JUST the dp will not reach the stock cat.

 

i bougt a 3 inch downpipe and it bolted right to my cat, but it was a ssautochrome

you should call racing beat and ask them, to be 100% sure

 

www.rx7.com's dp bolts to the cat or actually the precat pipe

 

I put that dp in along with the cat replacement pipe, and everything worked fine. Nothing had to be customized.

 

yeah....worked for me too..RB 2.5DP with MP bolts onto stock cat.....i got both the DP/MP sitting in my car..

 

You mean it hooks up to the stock CATBACK location, but not the CAT. The cat replacement pipe (presilencer) will go to the catback location just fine. His question was whether or not it would hook up to the stock CAT, the presilencer (cat replacement) would not allow this.

 

Stock catback, not cat, ie the name midpipe, replacing the stock cat.

 

OK so Im the guy hes talking about, well so I could get the rb down pipe, Im in AZ so I have emissions and have to have a cat, so would I buy the DP then buy another flange to weld to a high flow cat that bolt it to the DP , then weld the back of the cat the the rest of the exhaust?haha sorry if that confuses you.

 

If you wanted to run the stock cat with the RB downpipe you could put the DP in and have a custom pipe put in for the space between the dp and stock cat.


Or you could just get the corksport 3" tapered to 2.5" dp that will bolt to the stock cat.

 

ur first idea sounds like a good plan, thanks.

 

thanks guys.... but i also forgot to say he has to pass emmisions lol so no test pipes for him

 

Throw the cats back on for a day. It's not that much work.

 

So I could just unbolt the test pipe and bolt up the cats right? For emmisions.

 

If you're using the racing beat flywheel it'll be 2 pipes. The smaller one that is the gap between the dp and stock cat location, and the one that is 17.5" long (stock cat length). But yes you could.
