Hi all new to the group..Just got this 1988 IrocZ a few months back for my wife for out anniversary..Do you think this exhaust would be causing the car to spit and sputter??
This exhaust is so small I can take my Index Finger and Thumb and put it together around it..
Thanks,
John

 

No idea what might be the specific cause of your 'spit and sputter' problem (you'll need to provide much more info in order for anyone here to attempt a diagnosis), but I can tell you that such a restriction in the exhaust system will definitely cause a reduction in engine power output.

When tracking down a problem, it's always smart to fix the obvious stuff first; replace that jack-leg pipe with the correct piece, and then go from there.

 

Wow that is awful, I fixed a similar issue on my friends firebird and a weird lag problem he had when hitting the gas went away

 

I think that's the worst violation of that sort I've ever seen.

It's a crime and a sin to deprive some deserving lawn mower of its old exhaust like that.

 

That picture of the exhaust is epic.

 

I keep coming back to look at this beautiful mess I hope the OP gives us more info

 

I put a new TPS on it and don't have the sputtering anymore.
im going to take and cut the exhaust of the car. Does anyone have an ideal of what exhaust I can run on it with headers I want at least a 2 1/2 inch to 3 inch one..
And is this correct 40414DDA engine 305?
Thanks
