Default exhaust ideas are brewing

next mod has to be the exhaust for me...

first plans are a high flow cat... i can find one just as soon as the 2.5" diameter is verified...

i will prolly keep the stock muflers, i dont want a loud car this time... and i will be getting some bad *** tips in summer when i dont have to polish them daily...

the res can stay right?

money is not available for ported manifolds yet....or>>>>

youll love your high flow, thats what i have , no need to remove resonator, it give a nice tone to the exhaust and good upgrade in top-end power. ive gain 2 mph on the quarter mile.

Keep going Haro, oh and by the way, ill take a look at those number you wanted me, dont had time yet sorry...


do you plan to change the downpipe?

yes, you would change the DP at the smae time as the headers, the stock downpipe and the manifolds are the most restrictive part of your exhaust.

When I got both my Aurora and Riviera exhaust done, the shop told me that the stock exhaust was 2.25" (main pipe) and that the split to duals was 1.75".

I had to have to rear exhaust manifold gaskets replaced not to long ago, and I was telling the Midas guy that I was looking into getting headers. When I went to pick it up he told me that the car already had headers on it, small headers, but still headers. I don't know enough about exhaust to know what I'm looking at, but was wondering if there'* any way he could have confused the stock manifolds with "small headers".

Most likely yes, he was confusing the stock manifolds for headers. They do have a look that could be mistaken easily.
