Speed engineering cat less ypipe fitment to corsa catback

Recommended Posts

Warranty is finally up on my Gmc and it’s time to do a full exhaust. I’m looking at the speed engineering 1 7/8s longtubes and cat less ypipe but want to run the corsa sport catback. Just wondering if anyone has done this and if the fitment between the two brands together would work. Thanks!

I’ve been looking up videos of these trucks with full exhaust like this and there not that bad unless you really get into it.

Video's and in cab noise are two different things.

 

If the corsa catbacks bolts up to the factory y-pipe and the speed engineering headers are designed to bolt up factory catback, then they should go together just fine.

 

I ran SE headers to a dynomax catback on my previous truck, it went together pretty good. It was loud as shit though without cats and a straight through muffler. Needless to say that didn't last long.

Depends on what Corsa you have. Touring is perfect with headers/catless y-pipe from personal experience but Corsa Sport is just brutally loud.

Wait, exhaust work voids warranty?...

Not exactly, the exhaust work wont but the headers might. If the engine takes a dump the dealer can take the easy way out and blame the headers.

I’m pretty sure putting longtubes on it would. Maybe not but I was always under that perception.
