I'm looking to do mods to the OE header (port match and remove pre-cat and restriction), i know i should do a header but cost is too much for me now and i think ill get 9/10th of the way there.

I will proably get a header later in life, but thats neither her nor there.

With my borla sport (race - the loud one) i like the current sound except the drone at 3k on the highway, but with the pre-cat removed i think it will be way too loud.

Can anyone recommend either a replacement or additional resonator /muffler that will bring the volume down to what it is now or maby a bit quiter on the highway with the header mod?

Thanks,
Jonathan

 

I run the Borla Sport (race) with decat header and loud isnt the word for it...its earth shattering!! hehehe...people can hear you coming miles away and its always funny to see their faces when they see a mini at the end of it hahaha..you'll love it!!!

(NOTE: Im already tone deaf btw hahahhaa)

 

A 6 inch diameter round Magnaflow, replacing the Borla resonator, should do the job. I have a 5 inch OD Magnaflow with a one ball and pre-cat delete OE header, very pleasant.

 

I fix the 3,000 rpm drone with my borla sport by keeping the revs between 3200 and 4000 on the highway.

 

Thanks for the suggestion k-huevo

Narzin, maybe ill try without the new muffler for a bit just for some laughs

nabeshin, i too find driving faster quiets it down a bit, so far so good!

Not necessarily faster, just stay in 5th.
