So, my exhaust rusted through at the resonator this weekend, and I saw it as a chance to upgrade.

My question is:

I ordered the 2.5 inch bolt up system that is lited for teh "civic coupe". I have a DX coupe, which has a different exhaust from the EX coupe (due to the placement of the cat). Will the 2.5 inch bolt up system mate right up to my Greddy DP, or should I have ordered a test pipe to go with the setup to match the space left for the EX cat?

Thanks.

 

You will need a cat or test pipe!
I am guessing you were running no cat before?

 

there was no cat, I had my greddy DP bolt right up to the rest of the exhaust.
