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?

what is wrong with the downpipe... i thought bonnevilles were ok....

wouldnt i change that the same time i do headers?

can i get a confirmation on that 2.5" dia

sopme people go to a 3" DP

SSEi'* have a 2.5 in exhaust

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 find that hard to believe....shop measurement error?

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.

and the Stock Manis are not that great in the Flow department
