Invidia Down Pipe on Perrin Cat Back
 

Hi Guys,

Anyway I have an 86 currenntly running a Perrin 2.5inch cat back and I'm upgrading the headers, overpipe and front pipe soon. Basically I've been offered a new Invidia catted front pipe for a bargain price (which is pretty rare in Australia!) so I'm keen to throw it on. My only concern is that the front pipe wont meet up with the mid pipe properly. I mean they're both designed to join up with the stock system, but I dunno if there could be something bizarre going on with the flanges or bolt/nut sizes that could suddenly cause an issue.

Anyone had any experience mounting up different exhausts? Sorry if this has been covered before, I searched and searched without any luck.

they should mount up fine, i'm running borla uel header > perrin overpipe > invidia front pipe > invidia q300 and everything bolted up without issues.

Awesome thanks for the reply mate.

I needed to know the same thing thank you. I bought the car with a Perrin Cat back already on it I would like to add the non cated resonated front pipe to it. Though it shouldn't be a problem but thanks for confirming!:cheers: Cheers!

I am running stock header, perrin overpipe, invidia catted front pipe and a resonated 2,5" perrin catback.
Mounts up with no issues.
