I'll post a video of my Borla later. No cats and it doesn't "sound like ass".

[cemnt guy]

[Black cobra]

alright thanks

[Black cobra]

trust me your mod motor will sound like ass with slp ! your more than welcome to come to my garage and listen to a 4v with long tubes and 40 flows or 2v with long tubes and super 40.

I agree with you, SLP on mustangs just dont sound right too raspy!
Now slp sounds the best on an ls1 !! and all ls motors for that matter.

And I would love to come and hear ur stangs!! =)

i heard a couple of slp 2's with a catted x that sounded good. The lm 1's though imo dont sound to good on mustangs.

[cemnt guy]

i agree the gm cars soung good with it,ive heard them at wexford couple times and they sound good. also long tube headers will make your car sound much better also.

Long tubes made mine quiter... 1 3/4 tubes into a 3" collector.

I was looking at BBK shorty headers that should fit my BBK O/R H pipe
for 289 off ebay new.

Now long tubes or shortys? and WHY?

[cemnt guy]

mac ceramic long tubes can be had on ebay for 400 or less shipped. as for headers go long or go without! once again thats just my opinion

why, dont the shortys sound or more power?
See I have The BBK O/R H pipe that bolts 2 the stock headers and I think
They would bolt right up 2 The BBK Shortys..

[John4cam]

The torque you get from LT's works out great for 4valves since they lack it. Stay away from mac headers, get something with a solid flange like hooker, or bbk.

ok thanks
