LT4 exhaust on a ZR-1

[-=Jeff=-]

So I have been running Corsa for several years. I need a no resonance exhaust, but the snap crackle pop does seem to get annoying at times.

I had a chance to get a very low mileage LT4 Exhaust to try out, I wanted to see how is sounds

Initial impressions are good to me, but I only drove it a short bit. I do have a couple small leaks I need to fix but it was a nice clean modification, Granted I am running Watson Headers (2") and a pair of Magnaflow 3" Cats.

here are some pictures of the interface at the head pipes

Looks good, nice job. LT4 exhausts are suppose to the most free flowing of the stock C4 exhausts. Had one on my 91’ L98, even sounded good.

It looks awesome... and completed in the garage. :thumbsup::thumbsup:

Let us know how it sounds and breathes when you get to drive it more.

I used this:
https://www.amazon.com/Lisle-17350-Pipe-Stretcher-Kit/dp/B005ADY8V4/ref=sr_1_1?ie=UTF8&qid=1523493446&sr=8-1&keywords=lisle+exhaust+pipe+expander&dpID=51Q77LKyz9L&preST=_SX300_QL70_&dpSrc=srch

I will say that the bends are all OEM. I just cut the one side and stretched it and it lined up. The piece on the car was an extra piece I had, but will be swapping to one that is a bit longer to help mitigate a couple leaks

Added picture with one end stretched with the tool.. needed to swap between 2 dies.. took 45mins..

sealed the joints tonight.. hoping for no leaks..

Hans the Magnaflows are a much better (easier) fit

Yeah, that’s the conclusion I came to. Much simpler to install.
