What is the best bolt on exhaust for a stock 1.8L Djet? I am looking at many different models of Bursch but not sure which one.
thanks

A stock 1.8 is going to be L-Jet, just FYI.

I hit enter too quickly but, you are correct and it works great, any exhaust ideas?

1.8L ...for a little more power?


Drop the 1.8L and put in a 2L or 2056. I had a 1.7L stock muffler then free flow exhaust; no difference. Dropped the 1.7L and put in a 2056; wow. It's like a different car.

That is the answer I was expecting, did you buy a 2056 or have one built by scat or raby or other?

Bolting on exhaust will not give you magic power. The exhaust is part of a system that needs to be tuned to work together. You can bolt on the highest dollar exhaust bling and not see improvement. It's a system.

I picked up the 2056 from Garold Shaffer for less than $1k including dual weber carbs. Put SSHE on the exhaust with Bursch muffler. I removed the heads and inspected everything and put it back together. It runs good and pulls real hard. Huge difference over the 1.7L/1.8L engines I had in the car.

I replaced my horribly noisy Bursch with a Triad exhaust on the 1.8L. Then I purchased a Scat 2056 long block and did the engine switch. Excellent drivability with the L-Jet FI and sounds GREAT. Also replaced the fuel lines, master cylinder and media blasted the fan housing on the same go.

Did you put a bus throttle body on it? That will really wake it up.

L-Jet bus throttle body conversion.

Clay,
Thank you for the recommendation. I will certainly do the upgrade to complement the 2056 and the 42x38 valves. It's already pretty zippy as it is but more is better.
